My daughter gave me one of these strips about 3 years ago and I loved it. My nose blackheads were so bad I looked like a strawberry. When I pulled it off it looked like hundreds of trees growing from it, so bad. I used one a month later and to this time I have no blackheads at all. I still use once in a while but there is never much on there is anything at all. I have heard people say they come back but mine never have.
