I know you gotta have a prescription. I'm on my 5th day...It works for sure...all the acne on my face is gone except my forehead. But thats cuz I have long hair so I sweat behind it. It really drys the hell outta ur face. My chin area..where I had acne...feels like its burnt. Feels like skin is rippin when I open my mouth, but I screwed up by using my toner/astringent and using too much. I was smearin my chin with it. So far so good...except the redness and burning feeling.
