What layer of the skin does microdermabrasion exfoliate?

• A. Stratum Corneum
• B. Epidermis
• C. Dermis
• D. Stratum Granulosum

Answer: (A)

Microdermabrasion works by physically removing the outermost skin cells, so the layer exfoliated is the stratum corneum. This is the outermost part of the epidermis, made up of dead keratinocytes that shed off over time. By abrading this top layer, you reveal fresher skin underneath and can improve texture, tone, and how products absorb. The epidermis includes all its layers, with the dermis beneath it, and the stratum granulosum is a middle layer—not the primary target of this exfoliation.
