Exfoliation involves which skin layer when performed by licensed professionals?

• A. Dermis
• B. Stratum Corneum
• C. Epidermis
• D. Subcutaneous tissue

Answer: (B)

Exfoliation targets the outermost dead skin cells, which sit in the stratum corneum, the topmost layer of the epidermis. By removing these surface cells, the skin becomes smoother and products can penetrate more effectively. The deeper skin layers—the dermis and the subcutaneous tissue—are not the layers exfoliated in standard professional treatments. While the epidermis includes multiple layers, the action of exfoliation is specifically on the stratum corneum, the horny layer at the surface.
