This product is AMAZING. It's an official Holy Grail product of mine. I ideally use it once-a-week, and it feels as if angels themselves have taken the time, to delicately renew my skin with the magical touch of their wings. Ok, but really. I wear foundation daily, have combination and sensitive skin, and require hypo-allergenic products. I truly feel this product is a part of why it maintains week after week break-out free. I mix with equal parts water and vinegar and use the sensitive-skin time recommendation to avoid over-drying or any tenderness afterward, moisturize after and I'm good to go! I also find it works WONDERS as a spot treatment for the pimples that do happen to appear every-so-often. I love this stuff, use it often, and it still lasts FOREVER. Literally the best mask I've ever used.
