Alpha-hydroxyacid chemical peeling agents: case studies and rationale for safe and effective use.
Chemical peeling is an in-office procedure that involves the application of a chemical agent to the skin to induce controlled destruction or exfoliation of old skin and stimulation of new epidermal growth with more evenly distributed melanin. When peel agents reach the dermal layer, important wound-healing activities occur that cause skin remodeling and skin smoothing, both antiaging benefits. There are a number of key factors in selecting a peeling agent and procedure, and each is discussed. Variables to consider are the peeling agent and its formulation, the concentration of the agent, the patient's skin type, the site to be peeled, the skin preparation procedure prior to and immediately preceding the application of the agent, the application method, the duration of contact, and the patient's medical history and lifestyle. Various types of peels are discussed. Of particular interest are superficial chemical peels, which offer great flexibility over a range of skin types and conditions with minimal to no "downtime." Alpha-hydroxyacid (AHA) peels are superficial and can be combined with other cosmetic procedures in the office to maximize benefits. In addition, AHA peels work well when combined with supportive homecare products including AHAs or polyhydroxy acids (PHAs), topical retinoids, and antiacne/antirosacea treatments. Case studies are presented of patients using AHA peels for the treatment of acne and hyperpigmentation in a variety of skin types, including Asian skin.
