i have been using aczone for about 2 months now. my derm prescribed it as soon as it came out. my acne is severe to moderate. Aczone hasnt really been doing too much for me, i wonder if it is because im using it wrong? i put it on all my trouble areas at night and in the morning only a little on really bad areas because it is very drying to me. whats the deal? should i rub it in really good? do i leave big globs????
