I really love this product. I noticed a change almost overnight! It smooths out your skin, takes away the oily shine, and definitly leaves you feeling refreshed! It can also be used as an overnight spot treatment to quickly shrink pimples, though if you're going to do this be prepared to find a lot of dry green flakes on your pillow the next morning! You can't use this product too often though because it WILL dry out your face. I use it probably once every 10 days or so. Unforunately it smells very strongly and even after you wash it off the strong sulfur smell remains. Another unfortunate point is that it is very expensive! It's not something you can pick up for a few bucks at the local drug store unfortunately. However, that being said, drugstore sulfur masks, such as the one by AcneFree, don't work nearly as well as this. Most of them overdry my face to the point that I get irritation or a small rash. This wonderful mask by DDF does not.
