I suffer from terribly oily skin as well as severe acne. I have tried every over the counter product you can think. I've even had chemical peels and dermabrasion done at my dermatologist. I was getting ready to go on a prescription medication, but then I thought I'd give AcneFree's Severe Acne Treatment System a try. Within the first full day of using this product, I noticed a difference. My skin was a little more healthy looking and a little less oily. I even noticed some blemishes had gone. After 3 days I noticed even more of a difference. And after a week I was almost clear. I've been using it for 3 months now and I am acne free. I no longer suffer from oily skin and it took care of all the post acne marks as well. It's a great product, will almost get rid of the acne in 2 weeks, and does not overdry. I suggest using this product!!
