When I was fighting blackheads I purchased Bliss Sleeping Peel Mask and wasn't too happy with the results. The texture of this clay was very thick, which made it difficult to apply to my face. I applied a dime size amount to my nose, chin, and forehead. I initially only left the clay on my face for 5 minutes, but I didn't notice any changes in my blackheads so I decided to leave it on overnight. When I woke up the next morning the clay had disappeared for the most part and only a little residue was left behind. I noticed that I still had blackheads, but there was a definite change in amount. I decided to use this clay the following night and when I awoke in the morning I noticed that I had a new blemish on my nose. I figured it was just my acne acting up and didn't think too much of it. I continued to use this product for the next couple of nights and each morning I would notice a reduction in blackheads, but a new blemish would appear. Once I stopped using Bliss Sleeping Peel Mask Clay my blackheads returned, but I didn't get any new blemishes.
