I received this in one of my birchboxes a couple months ago and have used it several times. After applying it on my face, I wait about ten minutes, and then when I wash it all off with a hot towel, my face feels so refreshed and clean. I'm not even done using the sample, but I ended up buying the full sized product because I didn't want to run out. The only thing I can say about this is that it can be a bit messy, but hey, it is a charcoal scrub. Would definitely recommend.
