Facial TreatmentsQuestion 58 of 100

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

Explanation

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.
