Benzoyl Peroxide for Acne (Acne Vulgaris)

Kills the bacteria that cause inflammatory acne. The first thing to reach for when you have red, painful pimples.

Why it works for Acne (Acne Vulgaris)

Kills the acne bacteria (C. acnes) on contact inside the pore. The bacteria cannot become resistant to it, so it is the key partner that keeps topical antibiotics working. It also helps clear clogged pores a little. The AAD 2016 guidelines give it their top (Grade A) recommendation for both pimples and blackheads/whiteheads at 2.5-10%. The lower strength (2.5%) works just as well with less dryness and less bleaching of fabric.

How Benzoyl Peroxide works

Releases free oxygen radicals in the follicle that are bactericidal to C. acnes.
