Our pharmacists’ bottom line

Benzac (Benzoyl Peroxide) is a very popular topical acne treatment you can get over-the-counter or by prescription that may be better for people who don't want to take pill medication. Just be careful because it can bleach your hair, clothing and other fabrics.

  • Benzoyl peroxide is used to reduce bacteria on the skin, which "calms" the skin down (lowers the inflammatory response) in acne.
  • Helps stop blemishes from forming when oil and skin cells become trapped in pores.
  • Although Benzoyl peroxide can irritate the skin, a true skin allergy is rare.
  • Can be used in combination with acne pill medicine if your doctor thinks you need it.
  • It's available in non-prescription strengths, easy to buy at any drugstore and pretty cheap compared to prescription pills to treat your acne.
  • Higher strengths (concentrations) can cause skin irritation and may appear as redness, peeling, abnormal dryness or stinging, tightening, or burning sensations.
  • It's rare, that a serious allergic reaction would occur, but it's a good idea to test a small area of skin before using on any larger or sensitive areas.
  • Not the best choice if you're pregnant. Benzoyl peroxide is categorized as pregnancy Category C (weigh risks vs benefits) as compared to similar topical medicines that are in Category B (likely safe).
  • Can cause bleaching of hair and clothing.
  • May not work as well when used by itself over long period of time.
  • You'll need to stay out of the sun or apply a sunscreen if you have to be outdoors.

Tips from our pharmacists
  • Acne can take several weeks to show up in the skin so it's best to use for 2-3 months before you decide it doesn't work.
  • Studies showed it didn't matter what strength people used, they all took about the same time to work.
  • Higher strengths greater than 2.5% may not work any better but might cause more side effects.
  • Using a moisturizer that doesn't block your pores (non-comedogenic) may help lessen common side effects of skin dryness and peeling.
  • Taking good care of your skin is an important part of treating acne. Lightly wash with warm water and non-soap-based or gentle cleanser.
