Benzoyl peroxide is a widely used medication for the treatment of acne. It belongs to the class of drugs known as keratolytics, which work by helping to unclog pores and reduce the presence of acne-causing bacteria on the skin.

Benzoyl peroxide is available in various forms, including gels, creams, lotions, and washes, and is typically applied directly to the affected areas of the skin once or twice daily. It works by releasing oxygen into the pores, which helps to kill the bacteria that contribute to acne. Additionally, benzoyl peroxide helps to remove excess oil and dead skin cells from the surface of the skin, preventing pores from becoming blocked and forming new acne lesions.
