Has changed my skin, will never stop using

Best product I have ever bought for my skin. It can be used as a full face mask or spot treatment. I use it as a spot treatment on acne or if I feel like a acne spot is about to appear, and within a day or two the acne or spot is gone like magic. You can purchase on amazon for 13$ and it lasts forever. Comes in a powder form and you can add water or apple cider vinegar. Only need to one small spoon a week and your skin will look amazing
