I bought this for my daughter who had a serious breakout. It cleared most of her face except for the area in the forehead. It may be that she didn't use it twice a day. She only used it at night. I have occasional break outs especially in the summer. It really works for me. I will give it a 5 star for myself. But for my daughter who is 15 years old, it's not 100% improvement. I would say it improved 85%.
