The part I've bought for my brother who is in the midst of puberty. He seeehrr large blackheads on your nose that we could remove with the help of Komedonenhebers. 1 point deduction, there are unfortunately still: it helps only with pores that are ripe. You have to handle with it very carefully, because you can slip quickly. For small pores, it might also help, but the pain caused by the pressure is almost unbearable :(
