Alphahydroxy acids are a family of natural acids derived from fruits, milk, and other plants which, in small quantities, act as hydrators. In higher concentrations, they are exfoliants and work to reduce the effects of aging and sun damage by lessening the appearance of fine lines and wrinkles. The AHAs utilized in some Cell Tech products are not in any way synthesized and are therefore not comparable to the highly concentrated, synthesized AHAs used in acid peels.
