I really like these salts because they make your skin feel squeaky clean. Since it's just salt by itself, you need to:1) make sure your face is wet when you use it or2) add it to a face washBe careful for little cuts you might have because the salt will make it sting a bit. I gave this 4 stars because I used it up pretty quickly (washing my face with it once a day), and it was kind of expensive for the amount that you get.
