ABSTRACT
Chemical peelings are a procedure used for cosmetic improvement of the skin or for treatment of some skin disorders. Although a few years ago some predicted the disappearance of chemical peels in favor of lasers, quite the opposite has occurred. The popularity of chemical peels is related to their versatility and relative simplicity. The depth of the peel determines the final outcome, together with the patient's inconvenience during and after the procedure, healing time, and the rate of the potential side effects. Chemical peels, relevant for the treatment of facial atrophic post-acne scarring, include medium and deep peels, their combinations, and the chemical reconstruction of skin scars technique based on in-scar application of a high percentage of trichloroacetic acid (TCA). TCA is the most common chemical used in medium-depth peels. Skin preparation is important before a TCA peel performance. The TCA solution is compounded in a weight-to-volume preparation.
