Does a decent job

Overall this is a good product. I've used it twice, once on myself and once on my husband. It did a good job getting most of the blackheads out. Some it just pulled up far enough to get them with a pair of tweezers, but that was still acceptable. 

At this point, I can't say if it does anything to control oil over any period of time, since we have only used it once. Since it is cleaning out your pores, I'm assuming that over time it will help with the overall condition of your skin though.

One problem worth mentioning is that you do feel it when you peel it off. It does a great job pulling up the blackheads. However, it also catches all the tiny hairs that you don't really see. I know this can't be helped and this isn't any worse than any of the other products on the market that do similiar things.
