ABSTRACT
Alpha hydroxy acids (AHAs) are naturally occurring organic carboxylic acids, which are commonly found in foods. The first reported therapeutic benefit of these agents was reported more than two decades ago [1]; however, only recently have they been used in a myriad of skin products. AHAs were initially used to treat disorders of keratinization, including ichthyosis, xerosis, and psoriasis [2]. Despite the recent surge in AHA use, relatively little has been written regarding their mechanism of action.
