Hi I'm Shoni Morris and I'm here on behalf of Expert Village. Every one's skin is different so acne is different for everyone to. Someone with oily skin could use salicylic acid, benzoyl peroxide or H2O cream which is just a hydrogen peroxide cream. Someone with dry skin could use salicylic acid, benzoyl peroxide only one time per day as it could over dry the skin, H2O cream would perferable in the P.M only. Someone with combination skin could use either of the above mention product salicylic acid, benzoyl peroxide or H2O cream custom to how there skin is during the A.M and P.M. If you are dry during the day stick to the H2O cream or if you more oily during the day you could use salicylic or benzal peroxide. H2O cream should be use in the P.M only as it leaves a white film on the face.
