I chose this product because it had so many good reviews on other sites like Sephora and Ulta and also because-- and I hate to admit this-- it was expensive, so I assumed it would work. As others have said, it did work for a brief time. However, after about two weeks my skin began getting really bad. I will say that it seemed to shorten the break outs and clear them up a little faster, but it definitely did nothing to prevent them. Also, it really dried out my skin, which is two times as bad as before because not only am I breaking out and peeling from the product that isn't working, but it's making me have to put on so much moisturizer that I break out even more! I wouldn't recommend this. I've gotten to the point where I would rather put makeup over a pimple than have flaky looking skin. I am now using CeraVe and after only two days my skin it much more hydrated and I have no new breakouts.
