Can benzoyl peroxide really get rid of acne?

Benzoyl peroxide is a widely recognized, safe, and effective topical anti-acne ingredient, regarded in clinical practice as a first-line therapeutic agent. Chemically, it is classified as a potent organic peroxide possessing strong oxidizing properties. Typically appearing as a white crystalline powder, this ingredient is frequently formulated into gels, creams, and other topical preparations for dermatological treatment. Its efficacy in treating acne stems primarily from its ability to decompose and release "nascent oxygen," thereby effectively eradicating Propionibacterium acnes. Furthermore, it aids in dissolving follicular plugs, unclogging pores, and alleviating local inflammation; its therapeutic benefits are particularly pronounced in cases of acne accompanied by inflammatory lesions and pustules. However, this ingredient can be somewhat irritating; its use may trigger side effects such as skin dryness, peeling, and redness. Additionally, it possesses bleaching properties that may cause discoloration of clothing or hair; therefore, users are generally advised to begin with low-concentration products to allow their skin to gradually build tolerance.
