Benzoyl peroxide is a synthetic medication used as a topical agent for fighting bacteria and unclogging pores. It is one of the longest-used medications to treat acne and fight pimples.
Benzoyl peroxide is often used in acne treatments due to its antimicrobial properties. It also has a drying effect, so it is effective at minimizing oily build-up in the pores. Benzoyl peroxide penetrates deep into the pores of skin and delivers oxygen molecules that loosen any buildup of oil, dirt, or dead skin within the pores. It also kills any bacteria trapped in the pores or on the surface of the skin that could lead to acne or skin infections around minor breaks in the skin.
There aren’t many safety concerns with using benzoyl peroxide. In fact, it is listed as one of the safest and most effective medical ingredients by the World Health Organization’s List of Essential Medications.

Some people may discover they are allergic to benzoyl peroxide, so caution is advised when trying a new ingredient on your skin.
