Benzoyl peroxide exerts its antimicrobial action in the follicles and possesses bactericidal action against Propionbacterium acnes and Staphylococcus epidermidis. This activity is presumed due to release of active or free-radical oxygen capable of oxidizing bacterial proteins; resolution of acne coincides with reduction in Propionbacterium acnes and of free fatty acids on the surface of the skin.
