The Acne Spot Repair contains a high concentration of benzoyl peroxide (10%), which is the active ingredient that dries and clears blemishes. Since this is a highly effective ingredient at this concentration, it might slightly dry the skin around the blemish causing it to turn red and flake. This is a perfectly normal and common. On the other hand, if you experience any other reaction (e.g. itchng , burning), we recommend that you discontinue use and consult with a doctor. At MenScience we suggest a conservative approach to skincare – less is more – especially when using new products for the first time.
