European Academy of Dermatology and Venereology. Alpha hydroxy acids Cosmetics chemicals.
AHAs with greater bioavailability appear to have deeper dermal effects. AHAs are generally safe when used on the skin as a cosmetic agent using the recommended dosage. AHAs are a group of organic carboxylic compounds.
Understanding skin structure and cutaneous aging is helpful to a discussion of the topical action of AHAs.

Improvement of photodamaged skin with alpha-hydroxy acid AHA: They are often found in products that aid in the reduction of wrinkles as well as to soften strong, defining lines and improve the overall look and feel of the skin.
