Benzoyl Peroxide (C0005088)

Definition (NCI) A peroxide with antibacterial, irritant, keratolytic, comedolytic, and anti-inflammatory activity. Upon topical application, benzoyl peroxide decomposes to release oxygen which is lethal to the bacteria Proprionibacterium acnes. Due to its irritant effect, benzoyl peroxide increases turnover rate of epithelial cells, thereby peeling the skin and promoting the resolution of comedones. Benzoyl peroxide is used in the treatment of acne vulgaris.
Definition (MSH) A peroxide derivative that has been used topically for BURNS and as a dermatologic agent in the treatment of ACNE and POISON IVY DERMATITIS. It is used also as a bleach in the food industry.
