CSLB General Building (B) — All Questions

An esthetician has just finished using stainless steel tweezers on a client. What must happen before the tweezers are immersed in disinfectant?

• a.They must be immersed while still soiled so the disinfectant reaches the debris
• b.They must be washed with soap and water, rinsed, and dried✓
• c.They must be wiped with a dry towel and returned to the drawer
• d.They must be rinsed in cool water only, since soap deactivates disinfectant

Disinfectant cannot penetrate oils, makeup, or skin debris, so every implement must first be cleaned with soap and water, rinsed, and dried before full immersion for the labeled contact time. Immersing a soiled implement wastes the solution and leaves organisms alive. Dry-wiping and storing removes nothing. Soap does not deactivate a properly used disinfectant when the tool is rinsed and dried first.CCR Title 16 §979

Which statement correctly distinguishes cleaning, disinfection, and sterilization?

• a.Cleaning and disinfection mean the same thing and both kill bacterial spores
• b.Disinfection destroys all microbial life, including spores
• c.Sterilization is required for every implement used in a skin care establishment
• d.Sterilization destroys all microbial life including spores, while disinfection kills most pathogens on non-porous surfaces✓

Sterilization is the highest level and destroys all organisms including bacterial spores; disinfection kills most pathogens on hard, non-porous surfaces but not all spores; cleaning simply removes visible soil and reduces the number of organisms. Estheticians are required to clean and disinfect, not sterilize, because they do not penetrate living tissue. Cleaning and disinfecting are two distinct, sequential steps, not synonyms.

During a leg wax the applicator stick has touched the client's skin and the esthetician needs more wax. What is the correct action?

• a.Discard that applicator and use a new, clean stick for the next scoop✓
• b.Dip the same stick again since the wax is hot enough to kill germs
• c.Wipe the stick on the pot rim and reuse it on the same client only
• d.Flip the stick over and use the opposite end for the rest of the service

Once an applicator touches skin it is contaminated, and returning it to the pot inoculates the entire container for every future client. Wax temperature is far below the level needed to kill pathogens, so heat is not a safeguard. Wiping or flipping the stick still returns a used surface and used hand contact to shared product; a fresh stick per dip is the only acceptable practice.CCR Title 16 §979

An esthetician places metal implements in an EPA-registered disinfectant. How long should they remain in the solution?

• a.Until the next client arrives, regardless of the label
• b.For thirty seconds, which is standard for all products
• c.For the full contact time stated on the product's label✓
• d.Overnight, because longer is always better for metal

EPA registration is granted for a specific contact time, and the disinfectant only performs as claimed when implements stay fully immersed for that entire labeled time. A generic thirty seconds is not valid because contact times differ by product. Waiting for the next client is arbitrary and may be too short. Excessively long soaking can corrode or pit metal and is not what the label directs.CCR Title 16 §979

Which group of items must be discarded immediately after a single client because they cannot be disinfected?

• a.Wooden spatulas, cotton pads, gauze, and paper wax strips✓
• b.Stainless steel tweezers, comedone extractors, and metal bowls
• c.Glass electrodes and plastic mask bowls
• d.Metal brow scissors and steel lash tweezers

Porous items absorb fluids into their structure, so disinfectant cannot reach and kill everything inside them; wood, cotton, gauze, and paper are single-use and must be thrown away. Stainless steel, glass, and hard plastic are non-porous and may be cleaned, disinfected, and reused. Treating a porous item as reusable is one of the most common and most serious violations found on inspection.CCR Title 16 §979

A client's skin bleeds slightly during an extraction. What is the correct exposure procedure?

• a.Blot the area with a bare fingertip and continue the extraction
• b.Put on gloves, stop the service, apply pressure with clean cotton, discard contaminated single-use items in a sealed bag, and clean and disinfect the area and any implement with a hospital-grade disinfectant labeled effective against HIV and HBV✓
• c.Rinse the area with tap water and wipe the table with a damp towel
• d.Cover the spot with makeup and finish the facial

Any blood exposure requires gloves, standard precautions, containment of contaminated single-use items, and disinfection of surfaces and non-porous implements with a product carrying an HIV/HBV kill claim. Touching blood without gloves risks transmission in both directions. Water and a damp towel do not disinfect, and covering the site with makeup contaminates the makeup and delays wound care.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

What is the primary purpose of a Safety Data Sheet (SDS) in a skin care establishment?

• a.It lists the retail price and marketing claims of each product
• b.It certifies that a product is approved by the state board
• c.It replaces the need for product labels
• d.It provides hazard, handling, storage, first aid, and disposal information for chemical products used on site✓

An SDS is a manufacturer document describing a chemical's hazards, safe handling and storage, exposure controls, first aid, and disposal, and it must be kept accessible to every employee who works with the product. It is not a marketing sheet, not a state approval, and does not replace container labeling, which must still be intact and legible.Cal/OSHA Hazard Communication Standard (8 CCR §5194)

An esthetician follows 'standard' or 'universal' precautions. What does this mean in practice?

• a.Only clients who disclose an infection are treated as infectious
• b.Gloves are worn only when the esthetician can see blood
• c.Every client's blood and body fluids are treated as potentially infectious✓
• d.Precautions apply only to services that involve extractions

Standard precautions assume that any client may carry a bloodborne pathogen, because many carriers are asymptomatic and clients may not know or disclose their status. Relying on disclosure or on visible blood leaves the practitioner unprotected during the exposures that matter most. The principle applies to all services, not only extractions.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

How should a container of liquid disinfectant used for implements be maintained during the workday?

• a.Topped off with fresh concentrate whenever the level drops
• b.Kept covered, replaced according to the manufacturer's directions, and changed immediately if it becomes cloudy or contaminated✓
• c.Left uncovered so it can be reached quickly between clients
• d.Reused for a full month as long as it still smells strong

A disinfectant solution loses efficacy as it is diluted by rinse water and loaded with organic debris, so it must be kept covered, changed on the manufacturer's schedule, and discarded at once if it turns cloudy or visibly soiled. Topping off does not restore concentration. Odor is not a measure of strength, and an uncovered container evaporates and collects airborne debris.CCR Title 16 §979

A regular client arrives for a facial with an active, weeping cold sore on the lip. What should the esthetician do?

• a.Decline the service, explain that the condition is contagious, and reschedule after it has healed✓
• b.Perform the facial but avoid the lip area
• c.Perform the facial and apply extra disinfectant to the tools afterward
• d.Perform the facial while wearing two pairs of gloves

An active herpes simplex lesion is contagious and can be spread by hands, linens, and product containers, and manipulation or heat can also worsen the outbreak; the correct response is to decline politely and reschedule. Avoiding the lip area does not stop cross-contamination from droplets and hands. Disinfecting afterward and doubling gloves do not protect the client's own face or the establishment's shared product.CCR Title 16

What must be true of a disinfectant used on implements in a California skin care establishment?

• a.It must be a household bleach product of any concentration
• b.It must be a fragrance-free hand soap
• c.It must be EPA-registered, hospital-grade, and labeled bactericidal, fungicidal, and virucidal, and used per label directions✓
• d.It must be 100 percent isopropyl alcohol

The Board requires an EPA-registered, hospital-grade product with bactericidal, fungicidal, and virucidal claims, mixed and used exactly as the label directs. Hand soap is a cleaner, not a disinfectant. Undiluted or arbitrary bleach concentrations are not label-compliant, and pure alcohol evaporates too fast to hold a contact time and is not an accepted implement disinfectant.CCR Title 16 §979

An esthetician notices strong chemical fumes while mixing an exfoliating solution in a small treatment room. What is the best response?

• a.Open the product further to let it air out on the counter
• b.Hold her breath and finish mixing quickly
• c.Add water to the container to weaken the smell
• d.Improve ventilation, keep containers closed when not in use, and use the personal protective equipment listed on the SDS✓

Chemical vapors are controlled by ventilation, closed containers, and the PPE specified on the Safety Data Sheet. Leaving a product open increases vapor release, breath-holding does nothing about repeated daily exposure, and diluting a professional product off-label changes its performance and may create an unsafe or ineffective mixture.Cal/OSHA Hazard Communication Standard (8 CCR §5194)

A disinfected brow tweezer slips out of the esthetician's hand and lands on the treatment room floor. What must be done?

• a.Wipe it with a tissue and continue, since the floor was mopped that morning
• b.Clean it with soap and water and disinfect it again before use✓
• c.Spray it with alcohol and use it immediately
• d.Return it to the covered clean-implement container

A dropped implement is contaminated and must go back through the full process: clean with soap and water, rinse, dry, then immerse for the labeled contact time. A recently mopped floor is still not a clean surface. A quick alcohol spray does not provide a validated contact time, and placing a contaminated tool into the clean container contaminates every implement stored with it.CCR Title 16 §979

How must a stainless steel comedone extractor be handled between clients?

• a.Cleaned with soap and water, disinfected for the full label contact time, then stored in a clean, closed container✓
• b.Rinsed under hot water and placed back on the tray
• c.Wiped with a cotton pad soaked in toner
• d.Discarded after each client because it contacts skin

A comedone extractor is a non-porous, reusable implement, so it is cleaned, fully immersed in an EPA-registered disinfectant for the labeled contact time, dried, and stored in a covered clean container. Hot water and toner are not disinfectants. Discarding it is unnecessary because stainless steel can be effectively disinfected.CCR Title 16 §979

What is the correct handling of towels, sheets, and headbands in a skin care establishment?

• a.Folded and reused for the next client if they appear unsoiled
• b.Shaken out and hung to dry between clients
• c.Stored in the same bin as soiled linens to save space
• d.Used once per client, then placed in a closed container for soiled linens and laundered before reuse, with clean linens stored separately in a clean, closed cabinet✓

Linens are single-use per client and must be laundered before reuse, with soiled and clean linens stored in separate closed containers to prevent cross-contamination. Appearance is not a measure of contamination, since skin cells, oils, and microorganisms are invisible. Shaking soiled linens aerosolizes debris, and shared storage defeats the purpose of laundering.CCR Title 16

When must an esthetician wash her hands during a service day?

• a.Only at the start and end of the workday
• b.Only when gloves are not worn
• c.Before and after every client, after touching the face or any contaminated surface, and after removing gloves✓
• d.Only after handling money

Handwashing with soap and warm water is required before and after each client, after contact with contaminated items or surfaces, and after glove removal, since gloves can have unseen defects and hands become contaminated during removal. Limiting washing to the start and end of the day or to money handling leaves the majority of transmission opportunities unaddressed.CCR Title 16

Which statement about pathogens is accurate for a skin care practitioner?

• a.Viruses such as hepatitis B can survive on contaminated surfaces and are not treated by antibiotics✓
• b.Antibiotics kill viruses as effectively as bacteria
• c.All bacteria are harmful and cause disease
• d.Fungi cannot be transmitted in a salon setting

Hepatitis B is a durable virus that can remain infectious on surfaces, which is why an HBV kill claim matters on a disinfectant label, and antibiotics act on bacteria, not viruses. Most bacteria are non-pathogenic and some are beneficial; only pathogenic strains cause disease. Fungal infections such as tinea are readily transmitted through contaminated implements and linens.

A facial steamer has been used all week with tap water and now shows mineral scale. What is the correct maintenance approach?

• a.Continue using it, since scale does not affect the client
• b.Empty and clean the unit per manufacturer directions, descale it, and refill with distilled water✓
• c.Add a splash of implement disinfectant to the water reservoir
• d.Boil the reservoir water for ten minutes before each use

Steamers are maintained per the manufacturer's instructions, cleaned and descaled on schedule, and filled with distilled water to prevent mineral buildup that can cause spitting of hot water onto a client. Ignoring scale creates a burn hazard. Implement disinfectant is never added to a reservoir that produces breathable vapor, and boiling does not remove minerals.CCR Title 16

An esthetician uses the same unwashed makeup brush on two clients. This is an example of what type of transmission?

• a.Direct transmission through skin-to-skin contact
• b.Airborne transmission through respiratory droplets
• c.Indirect transmission through a contaminated object✓
• d.Transmission that cannot occur because makeup contains preservatives

Indirect transmission occurs when a pathogen moves from one person to another by way of a contaminated object such as a brush, implement, or linen. Direct transmission requires person-to-person contact, and airborne transmission travels through droplets or particles in the air. Cosmetic preservatives limit product spoilage but do not disinfect a brush between clients.

How should used cotton pads, gauze, and wax strips be disposed of at the end of a service?

• a.In an open basket beside the treatment bed
• b.In the same container used for clean supplies
• c.Rinsed and set aside for reuse on the same client
• d.In a covered, lined waste container that is emptied regularly, with any blood-contaminated items bagged separately✓

Single-use contaminated items go into a closed, lined waste receptacle so debris is not exposed to air, hands, or the next client, and items contaminated with blood are bagged and handled as regulated waste. Open baskets, shared clean-supply storage, and reuse all create direct cross-contamination pathways.CCR Title 16

A loyal client says she is comfortable with the esthetician re-dipping her wax stick because 'it's only my own germs.' How should the esthetician respond?

• a.Explain that the wax pot is shared with all clients, so no re-dipping is permitted regardless of client preference✓
• b.Agree, because a client may waive sanitation rules for her own service
• c.Re-dip only once and note it on the client's chart
• d.Re-dip but discard the top layer of wax afterward

A client cannot consent away a health and safety rule, because the contamination risk falls on every other client who uses that shared pot. Documenting the violation or skimming the surface does not remove organisms that have already dispersed into the wax. The correct answer is a clear explanation and a fresh applicator for every dip.CCR Title 16 §979

An esthetician has a small open cut on her finger on the morning of a full facial schedule. What is the appropriate action?

• a.Perform services as normal because the cut is small
• b.Cancel all services for two weeks
• c.Cover the cut with a bandage and a finger cot or glove, and keep it covered for every service✓
• d.Apply implement disinfectant to the cut before each client

An open lesion is a two-way route for bloodborne pathogens, so it must be covered with a bandage and a barrier such as a glove or finger cot for every service. Working with the cut uncovered exposes both parties. Cancelling two weeks of work is unnecessary, and implement disinfectants are not designed for use on skin wounds.Cal/OSHA Bloodborne Pathogens Standard (8 CCR §5193)

Which best describes acquired immunity?

• a.Protection a person is born with that resists all infection
• b.Resistance developed after exposure to a pathogen or after vaccination✓
• c.The body's physical barriers, such as unbroken skin
• d.The ability of a disinfectant to kill spores

Acquired immunity develops after the immune system encounters a pathogen naturally or through immunization, such as the hepatitis B vaccine. Natural immunity is what a person is born with, and unbroken skin is a component of that natural, non-specific defense. Spore-killing describes sterilization, not immunity.

After disinfection, how must clean implements be stored?

• a.Loose in a drawer with product samples
• b.In the disinfectant container permanently
• c.On an open tray beside the treatment bed
• d.Dry, in a clean, covered container or drawer used only for disinfected implements and labeled as clean✓

Disinfected implements must be dried and kept in a clean, covered, clearly designated container so they are not recontaminated by dust, spray, or hands. Storing them loose with other items or on an open tray exposes them again. Leaving them permanently in solution corrodes metal and does not meet the requirement for dry, covered storage.CCR Title 16 §979

Which practice is prohibited in a licensed California skin care establishment?

• a.Keeping a covered waste container in the treatment room
• b.Storing clean linens in a closed cabinet
• c.Keeping a pet in the service area or preparing and eating food where services are performed✓
• d.Posting the establishment license where clients can see it

Animals other than service animals, and food preparation or consumption in the area where services are performed, are prohibited because both introduce contamination. Covered waste containers, closed clean-linen storage, and a posted license are all required or expected practices rather than violations.CCR Title 16

An esthetician opens a new concentrate and estimates the dilution 'by eye' because the measuring cup is missing. What is wrong with this?

• a.A disinfectant only performs as EPA-registered when mixed at the exact label dilution, so it must be measured accurately✓
• b.Nothing, as long as the solution looks the same color as usual
• c.Nothing, because a stronger mixture is always safer
• d.It is acceptable if the implements are left in longer to compensate

EPA registration and the stated kill claims apply only at the labeled dilution; too weak fails to kill pathogens and too strong wastes product, damages implements, and increases skin and respiratory irritation. Color is not a measure of concentration, and extending soak time does not correct an incorrect concentration.CCR Title 16 §979

Why is 70 percent isopropyl alcohol generally more effective as an antiseptic than 99 percent alcohol?

• a.Because it is less expensive to produce
• b.Because it evaporates faster and therefore contacts more organisms
• c.Because higher concentrations are illegal in salons
• d.Because the water content helps alcohol penetrate the cell wall, and the slower evaporation extends contact time✓

Water in a 70 percent solution allows the alcohol to enter microbial cells rather than instantly coagulating the outer proteins, and the slower evaporation keeps the surface wet longer. Faster evaporation is a drawback, not a benefit. Cost is irrelevant to efficacy, and high-percentage alcohol is not itself illegal, just less effective as an antiseptic.

A salon owner points to a UV cabinet and says implements do not need liquid disinfection because the cabinet 'sterilizes' them. Is this correct?

• a.Yes, ultraviolet light sterilizes any implement placed inside
• b.No, a UV cabinet may be used only as a clean, covered storage container after proper cleaning and disinfection✓
• c.Yes, as long as the implements stay inside for one minute
• d.No, because UV cabinets are prohibited in California

Ultraviolet cabinets do not reliably reach every surface of an implement and are not accepted as a disinfection method; they may serve only as covered storage for items already cleaned and disinfected in an EPA-registered solution. Short exposure times do not change that. The cabinets themselves are not banned, they are simply not a substitute for disinfection.CCR Title 16 §979

A new client presents with an itchy, spreading rash of unknown origin across the cheeks and jawline. What should the esthetician do?

• a.Decline the service, refer the client to a physician for diagnosis, and rebook after medical clearance✓
• b.Perform a gentle facial and apply a soothing mask
• c.Diagnose it as contact dermatitis and recommend a cortisone cream
• d.Perform an exfoliating treatment to clear the rash faster

Estheticians are not permitted to diagnose or treat a skin disease, and an undiagnosed spreading rash may be contagious or a medical condition that services would worsen. The safe response is to decline, refer to a physician, and rebook after clearance. Naming a condition or recommending a medication is diagnosis and prescription, and exfoliating inflamed skin causes further damage.CCR Title 16

Which of the following signs would most clearly indicate that a client should not receive a service that day?

• a.Mild dryness with flaking on the cheeks
• b.Non-inflamed closed comedones on the forehead
• c.A warm, red, swollen area with pus draining from the skin✓
• d.Uneven skin tone from past sun exposure

Heat, redness, swelling, and drainage are classic signs of an active infection, which is a medical condition and an absolute contraindication for a service; the client must be referred to a physician. Dryness, closed comedones, and sun-related pigment changes are common cosmetic conditions that estheticians routinely address within their scope.CCR Title 16

Which sequence correctly lists the layers of the epidermis from deepest to most superficial?

• a.Stratum corneum, lucidum, granulosum, spinosum, basale
• b.Stratum granulosum, basale, spinosum, lucidum, corneum
• c.Stratum basale, spinosum, granulosum, lucidum, corneum✓
• d.Stratum spinosum, basale, corneum, granulosum, lucidum

New cells are produced in the stratum basale and travel upward through the spinosum, granulosum, and lucidum before reaching the corneum, the dead keratinized surface layer. The other sequences reverse or scramble the order. Remembering that the basale sits on the dermis and the corneum faces the outside world makes the direction easy to recall.

Which layer of the epidermis contains melanocytes and is where new skin cells are produced by mitosis?

• a.Stratum basale✓
• b.Stratum corneum
• c.Stratum lucidum
• d.Stratum granulosum

The stratum basale, the deepest epidermal layer, is where keratinocytes divide and where melanocytes produce the melanin that determines skin color and provides UV protection. The corneum is the dead outer layer, the lucidum is a clear layer found only on palms and soles, and the granulosum is a transitional layer where cells begin to die and fill with keratin.

An esthetician explains to a client why a superficial peel cannot 'remove' a deep wrinkle. Which layer holds the collagen and elastin that determine skin firmness?

• a.The stratum corneum
• b.The subcutaneous layer
• c.The stratum granulosum
• d.The dermis, particularly the reticular layer✓

Collagen and elastin fibers, blood vessels, nerve endings, and appendages sit in the dermis, with the reticular layer holding the dense structural network. Superficial peels act only on the epidermis, so they improve texture and tone but cannot rebuild dermal structure. The corneum and granulosum are epidermal, and the subcutaneous layer is fat and connective tissue below the dermis.

What is the primary function of the subcutaneous (subcutis) layer?

• a.Producing melanin for UV defense
• b.Providing fat storage, insulation, contour, and shock absorption✓
• c.Shedding dead cells to keep the surface smooth
• d.Manufacturing sebum for the acid mantle

The subcutaneous layer is adipose and connective tissue that cushions underlying structures, insulates the body, and gives the face its contour, which is why its loss with age contributes to hollowing and sagging. Melanin comes from the basal layer, desquamation occurs at the corneum, and sebum is produced by sebaceous glands in the dermis.

Which list best describes the major functions of the skin?

• a.Circulation, digestion, respiration, and reproduction
• b.Protection, sensation, heat regulation, excretion, secretion, and limited absorption✓
• c.Hormone production, filtration, and blood cell formation
• d.Bone support, movement, and mineral storage

Skin protects against injury and microorganisms, senses touch and temperature, regulates body heat through blood flow and sweat, excretes waste through perspiration, secretes sebum, and absorbs a limited amount of topically applied material. The other options describe the circulatory, digestive, endocrine, and skeletal systems rather than the integumentary system.

A 55-year-old client asks why her skin looks duller than it did in her twenties even though she exfoliates. What is the best explanation?

• a.Melanin production stops entirely after age 50
• b.The dermis is shed and replaced every month
• c.Exfoliation always thickens the stratum corneum
• d.Cell turnover slows with age, so dead cells linger on the surface longer and light reflects less evenly✓

Epidermal cell renewal takes roughly a month in a young adult and slows progressively with age, leaving more dead corneocytes on the surface and creating a dull, rough appearance. Melanin production continues but becomes uneven. The dermis is not shed at all, and appropriate exfoliation reduces rather than thickens surface buildup.

A client has very fair skin, red hair, freckles, and reports that she always burns and never tans. Which Fitzpatrick type best describes her?

• a.Type I✓
• b.Type III
• c.Type IV
• d.Type VI

Fitzpatrick Type I describes very fair skin that always burns and never tans, and it carries the highest risk of sun damage and skin cancer. Type III usually burns mildly and tans gradually, Type IV rarely burns and tans easily, and Type VI is deeply pigmented and rarely burns. The scale predicts response to UV and to exfoliating treatments.

A Fitzpatrick Type V client requests aggressive exfoliation to fade dark marks left by acne. What is the most important consideration?

• a.Darker skin tolerates any strength of peel without risk
• b.The service should be refused because darker skin cannot be exfoliated
• c.Higher Fitzpatrick types are more prone to post-inflammatory hyperpigmentation, so treatment should begin conservatively with sun protection and gradual progression✓
• d.Fitzpatrick type only predicts sunburn and has no bearing on exfoliation

Melanocytes in higher Fitzpatrick types respond to inflammation by producing excess pigment, so aggressive treatment can darken the very marks the client wants to fade. A cautious protocol, gradual strength increases, and daily broad-spectrum sunscreen are the safe approach. Refusing entirely is unnecessary, and Fitzpatrick type is directly relevant to treatment aggressiveness, not just sunburn.

A client presents with deep, painful, interconnected nodules and cysts across the jawline and back with visible scarring. What is the appropriate esthetic response?

• a.Perform aggressive extractions to drain the cysts
• b.Recognize this as severe (grade IV) acne, refer the client to a physician, and offer only gentle supportive care within scope✓
• c.Apply a strong chemical peel to dry the lesions
• d.Advise the client to stop all skin care until the acne clears

Grade IV cystic acne is a medical condition that requires physician management, and cysts must never be extracted by an esthetician because incising or draining them is outside scope and causes scarring and infection. Aggressive peels on inflamed skin worsen the condition. Telling a client to abandon all care is neither helpful nor within the practitioner's role.CCR Title 16

What is the difference between an open comedone and a closed comedone?

• a.An open comedone is an infected cyst, a closed comedone is a scar
• b.An open comedone is a secondary lesion, a closed comedone is a primary lesion
• c.There is no difference; the terms are interchangeable
• d.An open comedone reaches the surface and oxidizes to a dark color, while a closed comedone is covered by skin and appears as a small white bump✓

Open comedones, or blackheads, are exposed to air so the follicular contents oxidize and darken; closed comedones, or whiteheads, remain trapped beneath the surface and look like small flesh-colored or white bumps. The dark color is oxidation, not dirt. Neither is a cyst or a scar, and both are primary lesions.

A client shows symmetrical brown patches across the cheeks and upper lip that appeared during pregnancy. What is the most likely condition and the most important home care advice?

• a.Rosacea; avoid all moisturizers
• b.Vitiligo; increase sun exposure
• c.Melasma; use daily broad-spectrum sun protection because UV and heat worsen the pigmentation✓
• d.Eczema; apply an exfoliating acid twice daily

Melasma is a hormonally influenced hyperpigmentation that typically appears as symmetrical patches on the cheeks, forehead, and upper lip and is strongly aggravated by UV exposure and heat, so daily broad-spectrum sunscreen is the foundation of any protocol. Rosacea presents as redness and papules, vitiligo is a loss of pigment, and eczema is an inflammatory dermatitis, none of which match the description.

A client diagnosed with rosacea books a facial. Which treatment element should be avoided?

• a.Prolonged steam, hot towels, and stimulating massage or brushing✓
• b.A cool, soothing gel mask
• c.A gentle, non-foaming cleanser
• d.Broad-spectrum sunscreen at the end of the service

Rosacea flares with heat, friction, and vasodilation, so steam, hot towels, aggressive brushing, and vigorous massage should be avoided. Cool masks, gentle cleansers, and sun protection are appropriate supportive care. Estheticians may provide calming treatment but cannot diagnose or treat the disorder medically.

A client arrives with red, cracked, weeping patches on the cheeks that she says is her eczema flaring. What should the esthetician do?

• a.Perform a full exfoliating facial to remove the flaking skin
• b.Decline treatment over the affected areas, refer her to her physician, and reschedule when the skin is intact and not inflamed✓
• c.Apply a prescription-strength steroid cream from the dispensary
• d.Massage the area vigorously to increase circulation

Broken, weeping, inflamed skin is an open route for infection and is a contraindication for services on the affected areas; the esthetician refers to a physician and treats only intact skin. Exfoliation and vigorous massage further damage a compromised barrier. Dispensing or applying prescription medication is outside an esthetician's scope.CCR Title 16

Which of the following is a secondary skin lesion?

• a.Macule
• b.Papule
• c.Vesicle
• d.Scar✓

Secondary lesions develop from primary lesions as the skin progresses or heals and include crusts, scales, fissures, excoriations, ulcers, and scars. Macules, papules, and vesicles are primary lesions, present at the initial appearance of a condition. Knowing the distinction helps an esthetician document skin accurately without diagnosing.

During skin analysis the esthetician notices a mole with irregular, notched borders, uneven color, and a diameter larger than a pencil eraser that the client says has recently changed. What is the correct action?

• a.Remove the lesion with a comedone extractor
• b.Apply a lightening product to even out the color
• c.Avoid the area, and privately advise the client to have it evaluated by a physician without naming a diagnosis✓
• d.Perform microdermabrasion over the area to smooth it

Asymmetry, irregular borders, color variation, larger diameter, and recent change are warning signs that require medical evaluation, and the esthetician's role is to avoid the area and encourage the client to see a physician without diagnosing. Removing, lightening, or abrading a suspicious lesion is both outside scope and potentially dangerous.CCR Title 16

Which client history item is a general contraindication that should prompt the esthetician to obtain physician clearance before treatment?

• a.A preference for unscented products
• b.Uncontrolled diabetes, recent facial surgery, or current use of a photosensitizing medication✓
• c.A history of seasonal allergies to pollen
• d.Wearing contact lenses

Uncontrolled diabetes impairs healing, recent surgery leaves compromised tissue, and photosensitizing medications increase the risk of burns and pigment change, so all warrant clearance before treatment. Fragrance preference and pollen allergies are simply noted on the intake form. Contact lenses are managed by asking the client to remove them for eye-area services, not by obtaining clearance.

How do UVA and UVB rays differ in their effect on skin?

• a.UVA penetrates more deeply and contributes to aging and pigmentation, while UVB primarily affects the epidermis and causes sunburn✓
• b.UVB penetrates the dermis and UVA cannot reach the skin
• c.UVA is blocked by window glass while UVB passes through freely
• d.Only UVB contributes to skin cancer risk

UVA has a longer wavelength that reaches the dermis and drives photoaging and pigment changes, while shorter UVB rays are the main cause of burning at the epidermal level. UVA passes through window glass more readily than UVB, not the reverse. Both wavelengths contribute to skin cancer risk, which is why broad-spectrum protection is recommended.

Which pair correctly separates intrinsic from extrinsic aging?

• a.Both are entirely genetic and cannot be influenced
• b.Both are caused only by lifestyle choices
• c.Intrinsic aging is caused by smoking; extrinsic aging is genetic
• d.Intrinsic aging is the genetically programmed decline over time; extrinsic aging comes from external factors such as UV exposure, smoking, and pollution✓

Intrinsic aging reflects genetics and the passage of time, producing gradual thinning and loss of collagen, while extrinsic aging is driven by controllable external exposures, with sun exposure the largest single contributor. The two are distinct but overlapping, and only the extrinsic component is meaningfully modifiable through sun protection and lifestyle.

During which phase of the hair growth cycle is waxing most effective?

• a.Telogen, because the hair is resting
• b.Catagen, because the follicle is shrinking
• c.Anagen, because the hair is actively growing and still attached to the follicle✓
• d.Any phase, because the growth cycle does not affect waxing results

In the anagen or growth phase the hair is firmly connected to the dermal papilla and is removed with the fullest structure, producing the longest-lasting result. Catagen is a brief transition phase and telogen is the resting and shedding phase, when hairs release easily but are already detaching. Because follicles cycle independently, regrowth appears at staggered intervals.

A client reports coarse dark hair growth on the chin and upper lip that began after a hormonal change. Which term describes this pattern in a female client?

• a.Hypertrichosis, meaning hair on the palms and soles
• b.Hirsutism, an excessive growth of terminal hair in a male pattern✓
• c.Alopecia, a loss of hair
• d.Trichoptilosis, a splitting of hair ends

Hirsutism describes excessive terminal hair growth in a male distribution pattern in women and is often hormonally driven. Hypertrichosis is excessive hair growth in areas that are not normally hair-bearing and is not pattern-specific. Alopecia is hair loss and trichoptilosis is split ends, neither of which fits the description.

Which statement about the skin's glands is accurate?

• a.Sebaceous glands secrete sebum that lubricates the skin, while sudoriferous glands excrete perspiration that helps regulate temperature✓
• b.Sebaceous glands regulate temperature and sudoriferous glands produce oil
• c.Both gland types produce only sebum
• d.Neither gland type is affected by hormones

Sebaceous glands are attached to hair follicles and produce sebum, and sudoriferous (sweat) glands excrete perspiration for thermoregulation and waste removal. Their roles are not interchangeable. Sebaceous activity is strongly influenced by androgens, which is why oiliness and breakouts often shift with hormonal changes.

A client with visibly oily skin complains that her skin also feels tight and looks flaky. How should the esthetician interpret this?

• a.The client is mistaken, because oily skin cannot feel tight
• b.The client has changed skin types permanently
• c.The client has an oily skin type with a dehydration condition, since dehydration is a lack of water and can occur in any skin type✓
• d.The client has dry skin and no oil production

Skin type reflects genetically determined oil production, while a condition such as dehydration reflects water content and can occur alongside any type. Oily, dehydrated skin is common and is treated with lightweight hydration rather than heavier oils. Skin type does not change from day to day, though conditions do.

A client's chin shows oozing blisters that have dried into honey-colored crusts and she says her child has the same thing. What should the esthetician do?

• a.Extract the lesions and apply an antiseptic toner
• b.Perform an enzyme mask to dissolve the crusts
• c.Provide a facial while wearing gloves
• d.Refuse the service, refer the client to a physician, and clean and disinfect any surface the client contacted✓

Honey-colored crusting that is spreading within a household strongly suggests a contagious bacterial infection, which is an absolute contraindication and a medical matter. The esthetician declines, refers, and disinfects contacted surfaces and non-porous items. Gloves protect the practitioner but do not stop contamination of linens, product, and the client's own skin, and extraction or enzymes would spread the infection.CCR Title 16

Which description correctly matches the condition?

• a.Milia are dilated capillaries visible near the surface
• b.Milia are small, firm keratin-filled cysts trapped beneath the surface with no visible opening✓
• c.Telangiectasia is a keratin-filled cyst
• d.Sebaceous hyperplasia is a loss of skin pigment

Milia are hardened keratin trapped under the epidermis and appear as firm white bumps with no follicular opening. Telangiectasia refers to dilated capillaries showing as red lines, and sebaceous hyperplasia is an enlargement of sebaceous glands producing small doughnut-shaped bumps. Correctly identifying each keeps documentation accurate without crossing into diagnosis.

Why does an esthetician avoid stripping the skin with a very high-pH cleanser?

• a.It disrupts the acid mantle, whose slightly acidic pH helps limit microbial growth and reduce transepidermal water loss✓
• b.It permanently removes the stratum basale
• c.It causes melanocytes to stop functioning
• d.It thickens the dermis and creates wrinkles

The acid mantle is a thin film of sebum and perspiration with a mildly acidic pH that discourages microbial growth and helps hold moisture in the skin, so highly alkaline cleansers leave skin tight, reactive, and prone to breakouts. Cleansers act on the surface and do not reach the basal layer or the dermis, and they do not shut down melanocytes.

A new client arrives for her first facial. What should happen before any product touches her skin?

• a.The esthetician should begin cleansing and ask questions during the massage
• b.The client should be asked only whether she prefers a light or deep facial
• c.The esthetician should choose a protocol based on the client's age
• d.A consultation should be completed, including a health and medication history, allergies, prior treatments, and the client's goals and expectations✓

A documented consultation identifies contraindications such as photosensitizing medications, recent procedures, or allergies before any product is applied, and it aligns the client's expectations with what is realistic and within scope. Asking questions mid-service is too late to prevent a reaction. Preference and age alone do not reveal the medical history that determines whether a treatment is safe.

At what point in a facial should the formal skin analysis be performed?

• a.Before cleansing, so the esthetician can see the client's makeup routine
• b.After cleansing, using a magnifying lamp and appropriate eye protection✓
• c.At the end of the service, after the mask has been removed
• d.Only at the follow-up appointment

Makeup, sunscreen, and surface oil hide the true condition of the skin, so analysis is performed after cleansing, with a magnifying lamp and eye pads or goggles to protect the client's eyes from the light. Analyzing before cleansing gives a false reading. Waiting until after the mask or until a later visit means the treatment plan was never based on the skin's actual condition.

Which pair correctly describes mechanical versus chemical exfoliation?

• a.Mechanical exfoliation physically lifts dead cells with friction, such as a scrub or microdermabrasion, while chemical exfoliation dissolves the bonds between cells using acids or enzymes✓
• b.Mechanical exfoliation uses acids and chemical exfoliation uses friction
• c.Both types remove tissue from the dermis
• d.Chemical exfoliation is a mechanical process performed with a machine

Mechanical methods work by physical abrasion, including scrubs, brushing, and microdermabrasion, while chemical methods use acids or enzymes to loosen the intercellular bonds holding dead corneocytes together. The two definitions are not reversed. Neither method performed by an esthetician removes dermal tissue, since esthetic exfoliation is limited to the epidermis.

What is the correct approach to extractions during a facial?

• a.Continue extracting until every visible lesion is cleared, regardless of time
• b.Use a lancet to open the skin so the contents release easily
• c.Soften the skin first, use gentle even pressure with covered fingers or a clean extractor, limit the total extraction time, and stop if the skin becomes traumatized✓
• d.Squeeze with bare fingernails for better control

Extractions are performed on softened skin with gentle pressure through clean gauze or a disinfected extractor, kept brief to limit trauma and post-inflammatory pigmentation. Clearing every lesion in one visit causes bruising and scarring. Puncturing skin with a lancet breaks the skin barrier and is outside an esthetician's scope, and bare fingernails cut skin and transfer bacteria.CCR Title 16

During an extraction a closed comedone will not release after several attempts. What should the esthetician do?

• a.Increase pressure until it releases
• b.Use a needle to open the surface
• c.Apply a strong acid directly to the spot to dissolve it
• d.Stop working on that lesion, move on, and schedule a follow-up visit after further softening and home care✓

Forcing a stubborn lesion ruptures the follicle wall into surrounding tissue, causing inflammation, pigmentation, and possible scarring, so the correct choice is to stop and address it at another visit. Puncturing the skin is outside scope. Spot-applying a strong acid without control of depth or contact time risks a chemical burn.

Which mask selection best matches the skin condition?

• a.Clay or kaolin mask for oily, congested skin, and a hydrating gel or cream mask for dry or dehydrated skin✓
• b.Clay mask for dry, sensitized skin and a heavy occlusive balm for oily skin
• c.Any mask can be used on any skin type since masks stay on only briefly
• d.A strong drying mask for rosacea-prone skin to reduce redness

Clay and kaolin absorb excess sebum and are suited to oily, congested skin, while gel and cream masks deliver water and emollients to dry or dehydrated skin. Applying a drying clay mask to already dry or reactive skin worsens barrier damage, and occlusive balms on oily skin encourage congestion. Contact time does not make an inappropriate mask harmless.

Which massage movement is a light, gliding stroke used to begin and end a facial massage?

• a.Tapotement
• b.Petrissage
• c.Effleurage✓
• d.Friction

Effleurage is a light, continuous gliding stroke that relaxes the client and distributes product, which is why it opens and closes a massage sequence. Petrissage is kneading, tapotement is a light tapping or percussion movement, and friction is a deeper rubbing pressure, all of which are more stimulating and are used within the body of the sequence rather than at the transitions.

A client requests a full facial massage but has inflamed pustular acne across both cheeks. What should the esthetician do?

• a.Perform vigorous petrissage to break up the congestion
• b.Omit massage over the inflamed areas, since massage over active inflamed lesions can spread bacteria and worsen the condition✓
• c.Massage only with a heavy occlusive oil
• d.Massage the area longer to increase circulation and speed healing

Massage over inflamed pustular acne spreads bacteria across the face and increases inflammation, so those areas are avoided while unaffected areas may still be treated gently. Vigorous kneading and prolonged manipulation compound the damage. Heavy occlusive oils add follicular congestion to skin that is already impacted.

What depth of chemical peel may a licensed esthetician in California perform?

• a.Any depth, as long as the client signs a consent form
• b.Medium-depth peels reaching the papillary dermis
• c.Deep phenol peels under a physician's general instruction
• d.Superficial peels only, which affect the epidermis and do not remove living tissue below it✓

An esthetician's practice is limited to the non-living surface of the skin, so only superficial exfoliating peels acting on the epidermis are permitted. Medium and deep peels wound the dermis, are considered a medical procedure, and must be performed by or under the direct supervision of a licensed physician. A signed consent form does not extend a license's legal scope.CA Business & Professions Code

A client asks the esthetician to perform a 35 percent TCA peel she saw advertised online. How should the esthetician respond?

• a.Explain that a peel at that depth is a medical procedure outside esthetic scope, and refer her to a physician✓
• b.Perform it but shorten the contact time to make it superficial
• c.Perform it if the client signs a liability waiver
• d.Perform it on half the face as a test

A peel at that strength is designed to reach the dermis and is outside an esthetician's scope regardless of technique or paperwork; the correct response is a clear explanation and a physician referral. Reducing contact time does not reliably control depth on a medical-strength agent. A waiver cannot authorize unlicensed practice, and a test area is still the same prohibited procedure.CA Business & Professions Code

A client is scheduled for her first superficial AHA peel. Which combination of steps is most appropriate?

• a.Skip the patch test and begin at the highest available strength for faster results
• b.Advise the client to tan beforehand so the skin is conditioned
• c.Perform a patch test, start at a low strength and short contact time, watch the skin's response, and instruct the client on daily broad-spectrum sun protection afterward✓
• d.Instruct the client to use a retinoid the night before to enhance penetration

A first peel is patch tested and begun conservatively, with close observation during the service and strict sun protection afterward because freshly exfoliated skin is highly photosensitive. Starting at maximum strength invites burns and pigmentation. Tanning beforehand and layering a retinoid the night before both sensitize the skin and increase the risk of injury.

Which client is the poorest candidate for microdermabrasion?

• a.A client with mild surface roughness and dull tone
• b.A client with active inflamed acne, a rosacea flare, or recent isotretinoin use✓
• c.A client with occasional closed comedones on the forehead
• d.A client with mild uneven texture from past sun exposure

Microdermabrasion is mechanical abrasion of the stratum corneum, so it is contraindicated over inflamed acne, an active rosacea flare, or skin fragile from recent isotretinoin use, all of which can be torn or severely irritated. Dullness, mild roughness, and non-inflamed comedones are exactly the concerns superficial mechanical exfoliation is designed to address.

A client discloses that she has been taking isotretinoin (Accutane) for four months and requests a facial wax. What should the esthetician do?

• a.Perform the wax but use a gentler hard wax
• b.Perform the wax and apply a soothing gel afterward
• c.Perform the wax on a small test area first
• d.Decline the waxing service, explain that the medication makes skin fragile and prone to lifting and scarring, and rebook only after the client is off the medication for the period her physician specifies✓

Isotretinoin thins the epidermis and weakens its attachment, so wax can strip living skin and cause tearing, prolonged healing, and scarring; the service is declined and rebooked after the client's physician clears her, commonly around six months off the drug. Hard wax, aftercare gel, and a test patch do not change the underlying fragility of the skin.CCR Title 16

What is the correct technique for soft wax removal?

• a.Apply the wax in the direction of hair growth, hold the skin taut, and remove the strip quickly against the direction of growth, close and parallel to the skin✓
• b.Apply against the growth and remove in the direction of growth
• c.Apply and remove in the same direction, pulling straight up away from the skin
• d.Apply thickly in any direction and peel slowly for less discomfort

Applying with the growth coats each hair from base to tip, taut skin prevents lifting and bruising, and a fast removal against the growth close to the skin snaps hair out at the root. Pulling straight up or slowly increases pain and breaks hairs at the surface. Reversing the application and removal directions leaves hair behind and increases the chance of ingrowns.

Which of the following is a contraindication to waxing?

• a.Coarse terminal hair on the upper lip
• b.Hair that is at least one quarter inch long
• c.Recent sunburn, an active chemical peel, or topical retinoid use in the treatment area✓
• d.Client anxiety about discomfort

Sunburned skin, recently peeled skin, and skin treated with topical retinoids are all compromised and can lift or tear during wax removal, so those areas must be avoided until they recover. Coarse hair and adequate hair length are normal indications for waxing, not contraindications, and client nervousness is addressed with explanation and technique rather than by cancelling the service.

Before applying wax to a client's skin, what must the esthetician do with the wax temperature?

• a.Assume the thermostat setting is accurate and begin
• b.Test the temperature on her own inner wrist or another approved test site, and confirm it is comfortable before contact with the client✓
• c.Ask the client to touch the wax pot to judge the heat
• d.Heat the wax as hot as possible so it spreads more easily

Thermostats drift and wax heats unevenly, so a temperature test on the practitioner before every client is the safeguard against burns. Trusting the dial alone has produced many injuries. Asking the client to touch the pot exposes her to the burn risk directly, and deliberately overheating wax is the most common cause of thermal injury during hair removal.CCR Title 16

A client requests a lash and brow tint. What is the correct precaution?

• a.No precaution is needed because tints are cosmetic products
• b.A patch test is needed only for clients who report allergies
• c.The tint should be tested on the lash line itself
• d.A patch test should be performed at least 24 to 48 hours in advance, per the manufacturer's directions, and the service refused if any reaction occurs✓

Lash and brow tints and adhesives are common sensitizers that can cause severe reactions near the eye, so a patch test placed away from the eye and read 24 to 48 hours later is standard practice for every client. Self-reported allergy history does not identify first-time sensitization. Testing on the lash line defeats the purpose by exposing the eye to the very product in question.

Two days after a lash extension service a client calls reporting a swollen, red, painful eyelid with discharge. What should the esthetician advise?

• a.Tell her to stop using the lashes, seek medical evaluation promptly, and document the incident✓
• b.Tell her to apply an over-the-counter steroid cream to the lid
• c.Tell her to come in for a fill and the irritation will settle
• d.Tell her the reaction is normal and will pass in a week

Swelling, pain, and discharge around the eye suggest an infection or a significant allergic reaction and require a physician or eye doctor, not an esthetician; the incident should also be documented. Recommending a medication is prescribing, and applying more product or dismissing the symptoms delays care and can lead to permanent eye damage.CCR Title 16

Which combination of makeup practices is both technically and sanitarily correct?

• a.Dip the applicator directly into the jar and use green concealer to cover dark under-eye circles
• b.Use a lip brush directly from the client's mouth back into the lipstick tube
• c.Scrape product from the container onto a clean palette, use disposable or freshly disinfected applicators, and use a green-based corrector to neutralize redness✓
• d.Blow on brushes to remove excess powder before applying

Product is decanted onto a palette with a clean spatula so the bulk container is never touched by a used applicator, and single-use or disinfected applicators are used for each client. In color theory, green sits opposite red and neutralizes redness, while peach or yellow tones counter bluish under-eye shadows. Double-dipping and blowing on brushes both contaminate product directly.CCR Title 16

A client asks her esthetician to tattoo her eyebrows for a permanent result. What is the correct response?

• a.Perform it, since brow shaping is within an esthetician's scope
• b.Explain that permanent makeup involves puncturing the skin and is not authorized by an esthetician license, and refer the client to an appropriately permitted practitioner✓
• c.Perform it using a topical numbing prescription
• d.Perform it if the client has had it done elsewhere before

Tweezing, waxing, and tinting brows are within esthetic scope, but permanent makeup penetrates the skin with a needle and is regulated separately from the esthetician license, so it must be referred out. Prior experience elsewhere does not authorize the service, and obtaining or applying a prescription numbing agent is itself outside scope.CA Business & Professions Code

What is the purpose of properly draping a client and covering the eyes during a facial?

• a.It is only a matter of the salon's visual presentation
• b.It substitutes for cleaning the treatment bed between clients
• c.It allows the esthetician to skip the consultation
• d.It protects the client's clothing and hair, maintains modesty and comfort, and shields the eyes from steam, bright lamps, and LED or other light sources✓

Draping keeps product off clothing and hair, preserves the client's comfort and dignity, and eye protection prevents injury from steam, magnifying lamps, and light-emitting devices. Draping is a hygiene and safety measure, not decoration, and it never replaces cleaning and re-covering the treatment bed with fresh linens or a consultation.

How should a facial steamer be positioned and used during a treatment?

• a.Positioned an appropriate distance from the face, aimed so the vapor is comfortable, used for a limited time, and never directed at a client with a rosacea flare or heat sensitivity✓
• b.Placed as close to the face as possible for maximum penetration
• c.Aimed directly at the eyes to hydrate the delicate area
• d.Used for the entire duration of the facial for best results

Steam is kept at a comfortable distance and duration so it softens the skin without burning or overheating the client, and it is omitted entirely for rosacea flares, heat-reactive skin, and asthma-triggered clients. Close positioning and extended use cause thermal injury and excessive vasodilation, and aiming steam at the eyes is never appropriate.

Three minutes into a superficial peel the client reports intense burning and the esthetician sees blanching. What is the correct action?

• a.Reassure her and complete the full timed application
• b.Add a cool towel over the peel and continue
• c.Remove or neutralize the product immediately per the manufacturer's directions, cool the skin, and document the reaction✓
• d.Apply a second layer to even out the result

Intense burning with blanching signals that the peel is going deeper than intended, and the correct response is immediate removal or neutralization per the manufacturer's protocol, cooling, and documentation. Continuing the timed application or covering it while it keeps working allows further injury, and a second layer increases depth on skin already showing a warning sign.

What is the most important home care instruction after a superficial exfoliating treatment?

• a.Exfoliate again at home that night to extend the result
• b.Apply broad-spectrum SPF 30 or higher daily, avoid additional exfoliants and heat exposure for several days, and keep the skin hydrated✓
• c.Use a facial scrub twice daily for a week
• d.Avoid all moisturizer so the skin can breathe

Freshly exfoliated skin has a thinner protective layer and is highly susceptible to UV damage and pigment changes, so daily broad-spectrum sun protection plus a pause on other exfoliants and heat is the core aftercare. Additional scrubbing compounds the exfoliation and damages the barrier, and withholding moisturizer slows barrier recovery.

A client asks her esthetician for a dermal filler injection to soften a nasolabial fold. What is the correct response?

• a.Perform it if the esthetician has completed a manufacturer's training course
• b.Perform it under a physician's telephone instruction
• c.Perform it and record it as a 'volumizing facial'
• d.Decline, explain that injections penetrate the skin and are a medical procedure outside esthetic scope, and refer the client to a licensed medical professional✓

Any procedure that injects a substance beneath the skin is the practice of medicine and can never be performed under an esthetician license, regardless of manufacturer training, remote instruction, or how the service is labeled on a receipt. The correct response is a clear explanation and referral to a licensed medical professional.CA Business & Professions Code

A product label states a pH of 3.5. What does this tell the esthetician?

• a.The product is alkaline and will soften the acid mantle
• b.The product is neutral, like pure water
• c.The product is acidic, and because the scale is logarithmic it is significantly more acidic than a pH 5.5 product✓
• d.The pH value describes the product's thickness, not its acidity

A pH below 7 is acidic, 7 is neutral, and above 7 is alkaline, and each whole number represents a tenfold change, so pH 3.5 is roughly a hundred times more acidic than pH 5.5. That difference matters because low-pH exfoliating products act more aggressively on the skin. pH describes hydrogen ion concentration, not viscosity.

Which statement about emulsions used in skin care is accurate?

• a.An emulsion is a single pure substance with no separate phases
• b.An emulsion is a mixture of oil and water held together by a surfactant, and it may be oil-in-water or water-in-oil✓
• c.All emulsions are water-in-oil and feel heavy on the skin
• d.Emulsions do not require an emulsifying agent

An emulsion suspends one immiscible liquid inside another, and a surfactant or emulsifier keeps the droplets dispersed so the product does not separate. Oil-in-water emulsions feel lighter and are common in lotions, while water-in-oil emulsions are richer and more occlusive. Without an emulsifier the phases separate, and an emulsion is by definition a mixture, not a pure substance.

A client with dehydrated skin should look for which type of ingredient to attract and bind water in the skin?

• a.A strong surfactant such as sodium lauryl sulfate
• b.A denatured alcohol
• c.An abrasive such as aluminum oxide crystals
• d.A humectant such as glycerin, hyaluronic acid, or sodium PCA✓

Humectants attract and hold water in the stratum corneum, which is exactly what dehydrated skin lacks. Strong surfactants strip the barrier lipids, denatured alcohol increases evaporation and irritation, and abrasives are exfoliants that provide no hydration. In low humidity, humectants work best when paired with an occlusive or emollient to seal the moisture in.

How do alpha hydroxy acids (AHAs) differ functionally from beta hydroxy acid (salicylic acid)?

• a.AHAs are water-soluble and work mainly on the surface, while salicylic acid is oil-soluble and can penetrate sebum inside the follicle✓
• b.AHAs are oil-soluble and salicylic acid is water-soluble
• c.Both are oil-soluble and both dissolve only surface cells
• d.Neither affects the skin's pH

Glycolic and lactic acid are water-soluble AHAs that loosen bonds between surface cells, while salicylic acid is a lipid-soluble BHA that travels into sebum-filled follicles, which is why it suits oily and acne-prone skin. The solubility descriptions are not reversed. Both act at a low pH and both increase photosensitivity, so daily sun protection is required.

A client develops itching, redness, and small bumps only where a new serum was applied, appearing about a day after use. What is the most likely explanation and correct action?

• a.A normal purging response; the client should keep using the product daily
• b.A bacterial infection; the esthetician should recommend an antibiotic
• c.A likely allergic contact dermatitis; the esthetician should discontinue the product, note the ingredient list in the client's record, and refer the client to a physician if symptoms persist✓
• d.A sign the product is working; the client should apply it twice as often

A delayed, itchy, well-demarcated reaction limited to the application area is characteristic of allergic contact dermatitis, and the response is to stop the product, document the ingredients so it is avoided in future, and refer if symptoms continue. Continuing or increasing use worsens sensitization. Estheticians do not diagnose infections or recommend antibiotics.

An esthetician plans a galvanic desincrustation treatment. Which statement is correct?

• a.Desincrustation uses the positive pole to force product into the skin
• b.Desincrustation uses the negative pole with an alkaline solution to soften sebum and debris, making extractions easier✓
• c.Galvanic current is safe for all clients, including those with a pacemaker
• d.Desincrustation and iontophoresis are the same procedure

Galvanic desincrustation uses the negative pole and an alkaline solution to saponify sebum and soften follicular debris before extraction, while iontophoresis uses matched polarity to drive water-soluble products into the skin. Galvanic current is contraindicated for clients with a pacemaker, metal implants in the treatment area, epilepsy, pregnancy, open lesions, or a lack of skin sensation.

Before using a high-frequency device, which precaution is most important?

• a.Applying an alcohol-based toner right before contact to boost conductivity
• b.Having the client hold a metal object to complete the circuit
• c.Using it over open, bleeding extraction sites for a germicidal effect
• d.Keeping alcohol and other flammable products away from the electrode, and screening for contraindications such as pregnancy, a pacemaker, epilepsy, or asthma✓

High-frequency electrodes produce a spark, so flammable alcohol-based products must be removed from the area first, and clients who are pregnant or who have a pacemaker, epilepsy, or asthma should not receive the service. The device is used on intact skin with a light germicidal and drying effect, not on open bleeding sites, and no metal object is held by the client.

A client booked for microcurrent mentions that she has a cardiac pacemaker. What should the esthetician do?

• a.Decline the microcurrent service and offer a non-electrical alternative such as a manual facial✓
• b.Perform the service at the lowest intensity setting
• c.Perform the service but avoid the neck only
• d.Perform the service after asking the client to sign a waiver

Electrical modalities including microcurrent, galvanic, and high frequency are contraindicated for clients with a pacemaker or implanted electrical device because of the potential to interfere with it; the safe choice is a non-electrical service. Lowering the intensity, limiting the area, or obtaining a waiver does not eliminate an absolute medical contraindication. Other common contraindications include pregnancy, epilepsy, and active cancer without physician clearance.

Which statement about LED light therapy as used by estheticians is accurate?

• a.LED light burns away the outer layer of skin like a laser
• b.LED is a non-thermal, non-ablative light, with blue light commonly used for acne-causing bacteria and red light for stimulating and calming; eye protection is required✓
• c.LED is a laser device that estheticians may operate freely
• d.LED has no contraindications of any kind

LED panels emit low-level, non-thermal light that does not ablate tissue, with blue wavelengths targeting acne bacteria and red wavelengths used to stimulate and calm, and clients and practitioners should wear eye protection. LED is not a laser, and lasers are outside esthetic scope in California. Contraindications include photosensitizing medications, seizure disorders, and recent eye surgery.

Which practice reflects correct electrical safety in a treatment room?

• a.Running several devices through one outlet with a daisy-chained adapter
• b.Handling a plugged-in device with wet hands after removing a mask
• c.Inspecting cords for fraying, plugging one appliance into one outlet, keeping cords out of walkways, and unplugging by grasping the plug rather than pulling the cord✓
• d.Leaving all devices switched on and plugged in overnight for faster warm-up

Cord inspection, one appliance per outlet, clear walkways, and grasping the plug prevent shock, fire, and trip hazards, and equipment should be unplugged when not in use. Overloading an outlet is a leading cause of salon electrical fires. Touching a plugged-in device with wet hands risks electrocution, and leaving units powered overnight is both a fire and an energy hazard.Cal/OSHA

Which of the following is outside the scope of practice of a California licensed esthetician?

• a.Operating a laser to remove hair or pigment✓
• b.Applying a superficial exfoliating product to the epidermis
• c.Removing hair with wax or tweezers
• d.Applying makeup and performing a lash tint

Lasers and other light-based devices that alter living tissue are considered medical procedures and may not be operated under an esthetician license. Superficial exfoliation of the epidermis, temporary hair removal by waxing or tweezing, and makeup and lash services are all core esthetic services. The dividing line is whether the procedure affects living tissue below the surface.CA Business & Professions Code

A client asks her esthetician to administer a neuromodulator injection because 'a nurse taught you how.' What is the correct response?

• a.Perform it, since the esthetician has been trained
• b.Perform it if a nurse is present in the building
• c.Perform it and describe it as a spa service on the receipt
• d.Decline, explain that administering injections is the practice of medicine and outside esthetic scope, and refer the client to a licensed medical professional✓

Injecting any substance into the skin is a medical act, and training, proximity of a licensed professional, or creative wording on a receipt does not extend the legal scope of an esthetician license. Performing it exposes the licensee to discipline and the client to serious harm. The correct action is to decline and refer to a licensed medical professional.CA Business & Professions Code

What are a California esthetician's basic obligations regarding her license?

• a.It may be kept at home as long as a photocopy is in the salon files
• b.It must be renewed on the Board's schedule with the required fee, and the current license must be displayed at the licensee's work station or in the establishment where clients can see it✓
• c.It never expires once it has been issued
• d.It may be transferred to another licensee if the original holder stops working

California licenses are issued for a fixed term and must be renewed with the required fee before expiration, and the current license must be posted where the public can view it. A license never expires only if it is renewed. It is personal to the individual and cannot be lent, transferred, or represented by a photocopy filed away out of public view.CA Business & Professions Code

A Board inspector arrives at a skin care establishment during business hours without an appointment. What is the correct response?

• a.Refuse entry until the owner returns and schedules an appointment
• b.Ask the inspector to wait outside until all clients have left
• c.Permit the inspection, cooperate, and provide access to the premises, licenses, and equipment✓
• d.Ask the inspector for a warrant before allowing entry

Inspections of licensed establishments are unannounced by design, and licensees must permit entry and cooperate during business hours; obstructing an inspector is itself a violation. Demanding an appointment, delaying entry, or requiring a warrant for a routine regulatory inspection of a licensed business are all improper responses that can result in citation.CA Business & Professions Code

Which requirement applies to a licensed skin care establishment in California?

• a.It must hold a current establishment license and provide hot and cold running water and clean restroom facilities, and may not be used as living quarters with a direct opening into the service area✓
• b.Services may be performed in any private residence without a separate establishment license
• c.Running water is required only if chemical peels are performed
• d.An establishment license may be shared among several unrelated business locations

An establishment must be separately licensed, maintain hot and cold running water and sanitary restroom facilities, and be physically separated from living quarters. A residence used to provide services must meet the same establishment requirements. Water is fundamental to sanitation for every service, not just peels, and an establishment license applies to one specific location.CA Business & Professions Code

An esthetician realizes her license expired two months ago but she has continued taking clients. What is her situation?

• a.She is fine, because the Board allows a one-year grace period during which practice may continue
• b.She is fine as long as she pays the renewal fee before the end of the year
• c.She may continue practicing while the renewal application is in the mail
• d.She has been practicing without a valid license, must stop immediately, and must complete renewal before providing any further services✓

Practicing after a license expires is unlicensed activity regardless of intent, and it exposes the licensee to citation, fines, and discipline. There is a period during which an expired license can be renewed, but that is a renewal window, not permission to keep working. Services must stop until the license is restored to active status.CA Business & Professions Code

Which record-keeping and posting practice supports compliance in a skin care establishment?

• a.Discarding all product labels to keep the dispensary tidy
• b.Keeping the Board's health and safety rules in the owner's home for safekeeping
• c.Keeping current licenses posted, product and disinfectant manufacturer directions and Safety Data Sheets available on the premises, and maintaining client consultation and service records✓
• d.Recording only the services that generated the largest revenue

Posted licenses, on-site manufacturer directions and Safety Data Sheets, and client consultation and service records let an inspector verify compliance and let the licensee demonstrate that products were used as labeled. Discarding labels destroys the use directions and hazard information required to use a product legally, and off-site or selective records are of no use during an inspection.CCR Title 16

A salon owner asks an unlicensed receptionist to perform a quick brow wax because the esthetician is running late. What is the correct response?

• a.It is acceptable because brow waxing is a minor service
• b.It is unlawful, since only a person holding the appropriate current license may perform services for compensation, and both the individual and the establishment can be cited✓
• c.It is acceptable if the licensed esthetician watches from across the room
• d.It is acceptable if the client is told in advance and does not object

Performing licensed services without a license is unlawful, and the establishment and owner who permit it are also subject to citation and discipline. The simplicity of the service, casual observation by a licensee, and client consent do not create an exemption. Only students and apprentices in an approved program may practice, and only within that program's supervision requirements.CA Business & Professions Code

A client calls the day after a wax reporting a blistered, painful patch where the wax was applied. What should the esthetician do?

• a.Advise the client to seek medical care, document the incident and the products and temperatures used, and cooperate fully if the client files a complaint with the Board✓
• b.Tell the client it is a normal reaction and offer a free service
• c.Delete the client's service record to avoid liability
• d.Diagnose it as a burn and prescribe a topical antibiotic

A suspected thermal or chemical injury is referred for medical care, thoroughly documented, and handled honestly, since clients may file a complaint with the Board and accurate records protect everyone involved. Dismissing the injury delays treatment, altering or destroying records is misconduct, and diagnosing and prescribing are outside an esthetician's scope.CA Business & Professions Code

Which summary best describes the boundary of esthetic practice in California?

• a.Estheticians may perform any procedure taught in a manufacturer's certification course
• b.Estheticians may perform medical procedures if a physician is on the premises
• c.Estheticians may perform any service a client requests and consents to in writing
• d.Estheticians work on the surface of the skin using cosmetic preparations and approved devices, and may not diagnose or treat disease, penetrate the skin, inject, use lasers, or perform medium or deep peels✓

Esthetic practice is limited to beautifying and caring for the surface of intact skin with cosmetic products and approved equipment, and it excludes diagnosing or treating disease, penetrating living tissue, injecting, operating lasers, and performing peels that reach the dermis. Private certification courses, a physician's presence, and written client consent cannot expand what a license legally authorizes.CA Business & Professions Code
