L.P.
It is hard to sort through all the suggestions for solutions... but I have to recommend Proactiv, if you haven't tried it... I posted this same answer earlier today... read it if you are interested. Seriously, I used to suffer from acne, used all the dermatologist prescribed garbage, tried every OTC thing I could find, and Proactiv was the ONLY thing that ever worked for me, and it didn't tear my skin up in the process. I think they are selling the kits now for $20, and you'll know by the time you finish that one kit if it's working for you... so you won't be out a fortune if it doesn't... but in my experience, I saw and felt a noticeable difference in my skin in a week or so, with no serious reddening or drying. None. In fact, it actually soothed my skin.
Try it. That's all I can tell ya! And no, I don't sell Proactiv or anything, I just love the stuff.
