      Upsides and benefits
      DuacBenzoyl peroxide
      Coming soon.
      • 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.
      Downsides and risks
      DuacBenzoyl peroxide
      Coming soon.
      • 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 for people taking the medication
      DuacBenzoyl peroxide
      Coming soon.
      • 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.
