Benzoyl peroxide rash?

Benzoyl peroxide treatment
Thank you for your question. Redness, irritation, and dryness is a side effect of benzoyl peroxide, and severity of side effects is influenced by the strength of the medication. Generally, I recommend benzoyl peroxide 2.5% to the face and anything higher would be for the body. I cannot say what you are experiencing is either a side effect or allergic reaction because you need to be evaluated in person. Therefore, I highly recommend you consult with a board certified dermatologist to have your skin evaluated and to discuss treatment options that best suit your needs. Take care and good luck.
