I used it a while back and it worked for a short time. Then my acne came back with a vengence. It dried my skin out teribly, so when my acne came back the blemishes were hard and very painful. Some people get good results from it, some don't. All you can do is try it and see if it works for you. I was using 4 grams of it per day, split up in 2 doses. later
