Dries out pimples really well. Helps them come to a head if they have not yet. I like that I can truly spot treat because since my face is dry from all the acne products I don't to apply spot treatment anywhere but where I need it. With creams although I try to spot treat it ends up being a larger area than the bump site. I am very happy with it. Will continue to use it. I don't know that it works any better than when I use the Proactiv sulfur mask as a spot treatment. I will put a dab of that on a pimple before bed and it dries it out pretty good the next day. And it is much cheaper since it comes "free" with the proactiv 3 piece kit. But even so I bought this and I like it and still would buy it again.
