So I took a chance on this one, since it's kind of pricey. But holy moly!! It really does wonders! I use it once a week, I leave it on a bit longer, 5-7 minutes. Yes it does tingle/burn, I would imagine on more sensitive skin it would be very uncomfortable, but I like it. When I take it off, my face is tight, smooth and my pores are clear. This has definitely helped reduce my blackheads-which in turn reduces breakouts. It also is just a fantastic way to relax! I definitely plan on indulging in the big tub, but this seems to last a while, as I'm at two months, once a week use, and still a fair amount left! If you are struggling with blackheads, or just looking for an extra jumpstart in keeping your face clear, I highly recommend this!
