California Cosmetology Skin & Nail Services Practice Questions
Skin and nail services account for roughly one in twenty questions on the California cosmetology family of exams, and they are especially important for esthetician and manicurist candidates. This chapter walks through the anatomy you need to know before touching a client's face or hands, how to identify skin types, the standard facial sequence, waxing safety and contraindications, the basics of manicure and pedicure procedure, what makes nail enhancements legal in California (and what makes them illegal), and how to recognize medical conditions that require referral rather than service. The recurring theme is simple: stay within scope, stay sanitary, and do not service skin or nails that look diseased.
Sample Skin & Nail Services questions
1. A client asks for acrylic nail enhancements applied with methyl methacrylate (MMA) monomer. What must a California-licensed manicurist do?
California prohibits the use of methyl methacrylate (MMA) liquid monomer in nail products. Licensees must use ethyl methacrylate (EMA) or other approved monomers. MMA is brittle, hard to remove, and has caused injuries; a waiver cannot override a statutory ban.
BPC §73152. During lip waxing, after applying wax to one section of the lip, the esthetician should:
California sanitation rules prohibit double-dipping wax applicators. Once a stick touches the skin, it must be discarded; the next application requires a fresh, single-use stick. This prevents transferring bacteria back into the wax pot.
16 CCR §9793. A new client mentions she started oral isotretinoin (Accutane) two months ago for acne. She requests a brow wax. The correct action is to:
Isotretinoin thins the skin and dramatically weakens its barrier. Waxing can lift live skin, leaving raw wounds and scars. The standard contraindication window is at least 6 months after the last dose. A cooler temperature or patch test does not eliminate the risk.
4. Before applying wax to a client's leg, where should the practitioner test the wax temperature?
Standard safe practice is to test wax temperature on the inside of the practitioner's own wrist, where the skin is thin and sensitive. Testing on the client risks burning them, and a paper towel does not reveal how the wax will feel on skin.
5. A client's facial skin shows enlarged pores in the T-zone but dry, tight cheeks. This skin is best classified as:
Combination skin has different conditions in different zones, typically oily forehead/nose/chin (T-zone) and drier cheeks. Treatment must be tailored zone by zone rather than treating the whole face as oily or dry.
6. Which cranial nerve provides the main motor supply to the muscles of facial expression?
The facial nerve (cranial nerve VII) controls the muscles of facial expression. The trigeminal nerve (CN V) is mainly sensory for the face and motor only to the chewing muscles. Estheticians should know this when performing facial massage.
7. Which cranial nerve carries most of the sensation from the skin of the face?
The trigeminal nerve (cranial nerve V) provides sensory innervation to almost all of the face through its three branches: ophthalmic (V1), maxillary (V2), and mandibular (V3). The facial nerve is mostly motor.
8. Which is the correct general order in a basic facial?
A standard facial starts by cleansing the skin, then removes dead cells with exfoliation, optionally extracts where appropriate, moves into massage, applies a treatment mask, tones, moisturizes, and finishes with SPF for daytime sun protection.
