Ok so I have been using Benzoyl Peroxide for close to a year now and I am 95% clear (thankfully). But am left with red marks all over my face with very minor scarring. I received a 60g sample of Epiduo and was wondering if I could layer this compound I have for bleaching my skin on top of the redmarks still. I only apply the compound to my cheeks and would put the Epiduo on my entire face. Would this alter the effect of either drug?
