I've never had much acne until recently, so I was anxious to get rid of it. I tried Clenia (prescribed) first, but no fix. So I decided to buy this system. Within a few days there was a noticeable difference, and I haven't had a breakout since. It is greasy after adding all 3 steps, but I take care of that with a little powder. Good stuff! And you use just a little at a time, so it lasts.
