I've been using this for about two months or so now and I have to say that it helps a lot with closed comedoes. The first month or so I wasn't really seeing a difference (using only twice a week) and after that I decided to up the use to 3-4 times a week and see a difference! The closed comedoes starting to come to head and go away, while not completely gone, they definitely decreased! I love this product so much :)
