Benzoyl peroxide is a widely used topical treatment for mild to moderate bacterial folliculitis, particularly when caused by Staphylococcus aureus. It works by killing bacteria on the skin, reducing inflammation, and helping to keep hair follicles clear. This makes it especially useful for acne-like folliculitis on the chest, back, or face. It is available over-the-counter in concentrations ranging from 2.5% to 10% and can be found in washes, gels, and creams. While generally well tolerated, it can cause skin dryness, peeling, or irritation, especially when used too frequently or on sensitive skin. It’s also important to note that benzoyl peroxide is not effective against fungal folliculitis, which requires antifungal treatments instead.
