I am 35 and have (after I stopped taking the pill years ago) oily, blemished skin on the face, which is also very sensitive. I've tried all sorts of things. The only thing that is effective is tea tree oil, zinc oxide, fruit acids and the highest impact of all benzoyl peroxide. I have a few months Cordes BPO uses 3%. The effect was great, but the stuff has itched and burned on the skin that I could apply only with overcoming. Benzaknen 5% and 10% I can take much better and I have hardly any side effects. I turn to the cream always at night. Every 3-4 days I take a break and use a simple fat and moisturizing cream, then my skin is not too dry. All in all a recommended cream when applying it properly and carefully.
