One of the most studied, proven and dermatologist-recommended ingredients for treating acne, benzoyl peroxide targets the bacteria that cause breakouts. As an added plus, benzoyl peroxide products can also help ease the redness and inflammation associated with blemishes. Benzoyl peroxide improves acne quickly because it also promotes the skin’s natural exfoliation process, in turn minimizing the dead cells that can lead to clogged pores. The most common acne products with benzoyl peroxide are cleansers, lotions and spot treatments.
