I don't usually like using physical exfoliators as they can cause microtears on the skinst surface if they are harsh. This is a very mild and gentle exfoliator, which certainly does seem to keep blackheads away. However, if you are acne prone, you might want to consider using this in conjunction with a salysilic acid product, because this does not do anything for skin prone to breakouts. It does help even out skin texture and cleans the skin without drying it out. I use it only a couple or so times a week (mostly at the end of the day) or before applying heavy makeup.
