Which chemical treatment is commonly used to address aging skin?

• A. Glycolic mask
• B. Enzyme peel
• C. TCA peels
• D. Salicylic wash

Answer: (C)

A medium-depth chemical peel with trichloroacetic acid is used for aging skin because it penetrates deeper than lighter exfoliants, removing damaged outer layers and triggering collagen production during healing. This combination reduces fine lines, improves texture, and helps even out sun-damaged skin, which are common aging concerns. Lighter options like glycolic masks or enzyme peels exfoliate mainly the surface and can help with mild texture or pigment, but they don’t offer as much rejuvenation for deeper wrinkles. A salicylic wash is more aimed at acne and oily skin than aging. So the deeper resurfacing provided by TCA peels makes them the best choice among these for aging skin.
