Answer

Benzoyl peroxide products are also effective against C acnes (formerly P acnes), and bacterial resistance to benzoyl peroxide has not been reported. [39] Benzoyl peroxide products are available over the counter and by prescription in a variety of topical forms, including soaps, washes, lotions, creams, and gels. Benzoyl peroxide products may be used once or twice a day. These agents may occasionally cause a true allergic contact dermatitis. More often, an irritant contact dermatitis develops, especially if used with tretinoin or when accompanied by aggressive washing methods. [39] If intensive erythema and pruritus develop, a patch test with benzoyl peroxide is indicated to rule out allergic contact dermatitis.
