I have medium-heavy acne. My biggest problem is blackheads. I have tried so many treatments (ProActiv, Neutrogena, Clean & Clear, Clinique, etc) but NOTHING works. I read the reviews about this and bought it. I've used it every night for 2 weeks now, and see only a VERY slight difference. The first week my acne got worse, fast. I had 4 breakouts. but then they calmed down, and not my skin looks a little bit better, but not very noticeable. Is this my skin being resilient? Or is this a normal reaction?
