Benzoyl Peroxide safety

Basic chemistry, many studies, and decades of use have shown that benzoyl peroxide is safe and effective. However, there are a few things about which you may want to be aware.

  • There is a very low occurence of allergy to benzoyl peroxide. If you experience swelling of the skin or severe crusting, discontinue use immediately and consult a physician.
  • Less than 1:1000 people experience contact sensitization to benzoyl peroxide over time. Symptoms can be confused as a worsening of the disease but are in fact due to contact sensitization.
  • Benzoyl peroxide has not been studied in pregnant mothers. Consult your physician before using any medication, topical or otherwise, during pregnancy.
