Abstract/OtherAbstract:
BACKGROUND: With the advent of newer chemical peels, there is now a wide range of peeling agents that can be applied on specific patients. OBJECTIVE: The purpose of this study was to closely examine the more common chemical peeling agents at different concentrations. METHODS: The study methods were carried out by thoroughly cleansing the skin surface with acetone. Different concentrations of the chemical peels were applied on different skin areas (2 x 2 cm each) and left on the skin for 15 minutes: phenol-Bakers, 25%, 50%, 75%, 88%; trichloroacetic acid, 25%, 50%, 75%; glycolic acid, 50%, 70%; and pyruvic acid, 50%, 100%. Serial biopsies were taken from each peeling site at 1, 7, and 21 days post-peel. Biopsies were then evaluated for epidermal changes, inflammation, and collagen deposition. RESULTS: The results show that Bakers phenol peel caused the most inflammation and nonspecific reaction, and in addition, a proportionate amount of new collagen deposition. Plus, increasing concentrations of phenol and TCA caused increasing amount of epidermal sloughing and inflammation after 1 day post-peel. The extent of reaction from the phenol and TCA was directly proportional to the collagen deposition at 21 days. CONCLUSIONS: The glycolic acid and pyruvic acid caused minimal nonspecific reaction. However, the collagen deposition caused by the glycolic acid and pyruvic acid was disproportionately increased suggesting a direct stimulatory effect by the two agents.
