About this ingredient

Benzoyl Peroxide is a widely used topical active pharmaceutical ingredient with antibacterial and keratolytic properties, and a staple in dermatological treatment. It is available over the counter and as an FDA-approved prescription medication for acne vulgaris, where it works by killing Cutibacterium acnes, the bacterium associated with acne, and through mild keratolytic effects that help treat comedonal acne.[1]

As an oxidizing agent, Benzoyl Peroxide is converted to benzoic acid in the skin, releasing reactive oxygen species that oxidize bacterial proteins.[1] It is often used in combination with topical antibiotics or retinoids; combination therapy is more effective than either medication alone and helps prevent the development of antibiotic resistance.[1]

Benzoyl Peroxide can cause mild dryness, redness, and scaling, particularly at higher concentrations, and contact dermatitis has been reported in a small percentage of patients.[1] Prescribers should consider the concentration and formulation of Benzoyl Peroxide when weighing these effects.

Frequently asked questions

Will benzoyl peroxide bleach my clothes?

It can. Benzoyl peroxide bleaches fabric and hair on contact, including towels, pillowcases, shirt collars, and headbands. Let treated skin dry completely before dressing or lying down, wash your hands after applying, and consider switching to white towels and pillowcases while you use it.
