## Definition

A chemical exfoliant is a skincare product that uses acids or enzymes to dissolve the bonds between dead skin cells, promoting their removal without physical scrubbing. The two main categories are AHAs (alpha hydroxy acids like glycolic and lactic acid), which work on the skin's surface, and BHAs (beta hydroxy acids like salicylic acid), which penetrate into pores. Enzyme exfoliants from papaya (papain) or pineapple (bromelain) offer a gentler alternative. Chemical exfoliants improve skin texture, brightness, tone, and can help reduce acne, hyperpigmentation, and fine lines. They are generally preferred over physical scrubs because they provide more even, controlled exfoliation with less risk of micro-tears. Start with lower concentrations and use sun protection, as exfoliated skin is more susceptible to UV damage.
