NCIt definition : 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.;
