I absolutely love this mask. I began using this mask about 3 months ago. I had really bad skin and after using it for 3 months, along with other Avon products, my skin really cleared up. Upon application it is black, and when it dries it becomes grey in colour. I could actually feel it working on my skin. Nothing unpleasant. I used it 3 times a week and really saw a difference. I would recommend Avon ClearSkin products to anyone who is struggling with acne.
