Glycolic acid is a member of the alpha hydroxy acid family, which occurs naturally in foods and has been used for centuries as a cutaneous rejuvenation treatment. Recently it has proved to be a versatile peeling agent, and it is now widely used to treat many defects of the epidermis and papillary dermis in a variety of strengths, ranging from 20% to 70%, depending on the condition being treated. People of almost any skin type and color are candidates, and almost any area of the body can be peeled. We present our technique for the use of glycolic acid as well as histopathologic findings of skin treated with both glycolic acid and trichloroacetic acid at varying time intervals.
