Works well, a bit too tingly [SEP] I just recently started using the paper charcoal bubble masks but I do love peel off masks even more. I put on a medium layer of this and after a few minutes it starts to bubble. Unlike with the paper masks it was almost too tingly that made me want to just wash it off. But it went away after a few more minutes and then I just had to wait for it to dry. Maybe 20 minutes total. I like to leave peel off masks on longer to tighten my pores. It came of in just a couple pieces which was unusual, usually you have all these scraps left on. My skin looked and felt very fresh after.
