Promising review: "Wow. Just wow. I had no expectations for this product since I've been dealing with cystic acne since I was a teenager (I'm 24 now), so I went into this purchase not expecting much. As many others have said, I previously tried absolutely everything on the market to cure my acne. I have very sensitive, reactive skin and have never seen any real improvement. After reading all the crazy reviews about this product I figured I would give it a try, again, not expecting much. However, I have been blown away by the long-term results of using this mask. I mix it with apple cider vinegar and apply it several times a week when my skin is really bad, and it has never done anything negative to my skin – no irritation, no dryness, nothing. It always destroys every single pimple that emerges. It does bring underlying pimples to a head, and that can be a little disturbing at first, but it is so worth it for the end result. I was considering taking Accutane, a very strong and dangerous medicine to finally cure my acne for good, and this product has made me completely reconsider." —Heather E.
