Benzoyl peroxide

Benzoyl peroxide is a highly lipophilic, oxidising agent with keratolytic and bacteriocidal effects. The effectiveness of benzoyl peroxide in the treatment of acne vulgaris is primarily attributable to its antibacterial activity, especially with respect to Propionibacterium acnes. Benzoyl peroxide is also believed to be effective in the treatment of acne on account of its anti-inflammatory and mild keratolytic properties.
