Evaluation of abrasives in acne therapy.
Various abrasive materials, such as pumice, polyethylene, and aluminum oxide are widely used as adjuncts in the therapy of acne. The apparent rationale is that abrasion should unseat comedones and deter their formation. We assessed the efficacy of various abrasives and abradant pads. Varying degrees of peeling and erythema were produced, but there was no appreciable reduction of comedones. Aggravation was noted in some cases. Generally, the resorption of papules and pustules was enhanced.
