Benzoyl peroxide makes my 12 year old daughter break out in a red itchy rash and makes her face worse. salicylic acid doesn't work for her.

Too much too often: Benzoyl peroxide comes as 5% and 10%. The vehicle can also be a gel (most potent) to lotion to cream (least potent). It also doesn't have to be put on every day or twice a day. If it is irritating her skin tell her to hold back on the throttle, both in the formulation and the frequency. Acne is almost a right of passage of teenage hood and she will get through it as you and her mom did!
