  • The affected area should be thoroughly washed.
  • Benzoyl peroxide cream, lotion, or gel should then be applied sparingly once, twice, or three times daily as needed.
  • Topical cleansers should be used to wash the affected areas once or twice daily.
  • The frequency of use should be decreased if excessive dryness or irritation occurs.


  • Benzoyl peroxide is a topical medication used for treating acne (pimples). It is active against Propionibacterium acnes, a bacterium which has been associated with acne. Benzoyl peroxide works through several mechanisms. It kills the bacteria and promotes the growth of new skin cells. It also dries the skin. Increased cell growth leads to replacement of the pimple-containing skin with new skin.
