Hi I'm Shoni Morris and I'm here on behalf of Expert Village. Application of the acne treatment products is key the first step would be either you use your finger or a cotton swab to apply salicylic acid or peroxide only to the effected area. You dont wnat to get it on the skin that is not effect because it would over dry and make it look more pronounce. Hydrogen peroxide cream which is short H2O cream it could be applied to the P.M only to the entire face this would help prevent or treat acne that is already there.
