I bought this as a last hope for cystic acne. I bought Amazon's brand of raw apple cider vinegar with the mother to mix with the clay powder because I heard that worked best for people experiencing skin problems. My skin has been a rollercoaster for the past 5 years. But recently, things have gotten really out of control. My self esteem is the lowest it's been. This mask had been such a life saver. I'm not sure words can describe how impressed I am with this healing clay mask. Since my skin has been through hell and I've literally tried everything, it's pretty resilient so I've been using this mask every night for the last 4 days. It's not nearly as drying as I thought it would be so that hasn't been an issue. But the mask has dried up everything and I have no new breakouts. I was so happy that I cried. If I could give this product a million stars, I would!
