I purchased this from Ulta. I enjoy a couple of MB other things, so gave this a try. I have sensitive, combination oily, acne prone skin. This product says you can use it on either cystic acne or small acne clusters emerging on the skin. I used it for two weeks straight on a small area of breakout on my face and didn't notice much of a change in my breakouts at all. I feel like I was just rubbing alcohol with baby oil on my face (the best way I can describe this stuff). I don't think it's worth the price, and I doubt it would work on cystic acne. I have gotten two cystic acne pimples last summer, so I get that rather infrequently, and can't comment on the product on cystic acne.
