What is benzoyl peroxide? Who invented it?

BPO MDacne acne

The first mention of the medical use of benzoyl peroxide dates back to 1929, where Lyon and Reynolds reported effective treatment of burns, wounds, and varicose veins by benzoyl peroxide [1]. Subsequently, it was found that it has antibacterial [2,3], anti-inflammatory [4], keratolytic [5], and wound healing [6.7] effects.

Presently, benzoyl peroxide is a widely used agent for acne treatment because of its efficacy and good tolerability in patients [8,9]. Benzoyl peroxide is a good alternative to topical antibiotic for the treatment of Acne vulgaris caused by antibiotic-resistant strains, for example, Propionibacterium acnes [10,11].
