What type of peel is often administered by estheticians using glycolic acid in lower concentrations?

The correct answer is the light peel. Light peels, often performed by estheticians, typically involve the use of glycolic acid at lower concentrations. This type of peel primarily targets the outermost layer of the skin, providing benefits such as exfoliation, improved texture, and enhanced radiance without significant downtime. The use of glycolic acid is particularly effective in these low concentrations, as it acts to slough off dead skin cells, stimulate collagen production, and promote skin rejuvenation.

Superficial peels, while similar, usually use different acids and target the same outer layer of skin, but the specific procedural focus on glycolic acid in lower concentrations characterizes the light peel distinctly. Medium-depth and deep peels involve stronger concentrations or different types of acids, leading to more substantial treatment effects and increased recovery time, which differentiates them from light peels.
