My sister is a huge fan of Proactiv and she actually got me hooked on it a few years back. She had been using it for a couple of years and her skin really looked nice. I mean you really could tell that her skin was looking great! So I decided to try it and I have not had a severe breakout in months. I have the best looking skin I have had in a long time and I have terrible skin. This stuff is really all that it says to be and more. I could not have been happier. Of course some people have used this product and it has not worked for them but that is because everyone has different skin and everyone reacts differently. You just have to try it and give it a chance. This was by far the best treatment for my skin. I am so glad that my sister used and it worked on her because that is why I tried it.
