I couldn't believe when I read the other reviews about this product. Had to try it myself. So I figured if it had a 30 day money back guarantee I would try it. It not only did not work, but it made my skin so much worse. I was getting huge cyst like pimples and I never had that. I thought maybe I just needed to get used to it and that your skin always gets worse before it gets better. Not the case with this product. I stopped using it and my skin cleared up or should I say went back to normal. I did not want to leave a bad product review without contacting the manufacturer first. Unbelievable! Money Back guarantee my A**!!!!! They sent me an email stating that since I already used the product they cannot refund me. HUH? don't you have to try it to see if it works for you?????? WTF!!!! Anyway, needless to say I'm not happy. I should have listened to the reviews. These are really helpful. Heed my warning...do not deal with Murad! or at least the company that is selling it.
