What are those one strips that you can use to remove blackheads?

I heard of them somewhere, but forgot the name. They are strips you can put on your face, and they take the blackheads out.





If anyone knows what they are, do they really work?What are those one strips that you can use to remove blackheads?
i think its biore and you cn find them in any grocery store. or walmart, so forth. anyways, what you do is put them on when you gt out of the shower.. i always thought that that worked better because your face was nice and clean and open for the black heads to come out. then you leave it on for the time alotted and peal them off. i have used them and they worked ok but, other people i have seen used them and worked great.. hmm hehe. goodluck
