The mechanism of action of benzoyl peroxide has not been determined but may be related to its antibacterial activity against Propionibacterium acnes and its ability to cause drying and peeling. Benzoyl peroxide reduces the concentration of free fatty acids in the sebum. Little is known about the percutaneous penetration, metabolism and excretion of benzoyl peroxide, although it is likely that benzoic acid is a major metabolite. There is no evidence of systemic toxicity caused by benzoyl peroxide in humans.
