Considerations in alpha hydroxy acid peels

Alpha hydroxy acids (AHAs) have been used as cosmetic agents since ancient times. In low concentrations AHAs cause a decrease in corngocyte cohesion. In higher concentrations they result in epidermolysis and upper dermal changes, producing a vibrant, less wrinkled, and more uniformly colored skin. The method of application is important as is decreasing pH to increase the AHA bioavailability.
