I've been using these strips once a week for the last two months and I really do like then. I don't have blackheads but I do have large pores and oily skin. The strip is easy to apply and work quite quickly. My nose feels smooth and my pores are tightened. One thing I have to mention is don't leave the strip on too long. I did that once and left it on for 30 minutes, it was so painful to remove and did not have any additional effects. Nose strips have become a regular part of my beauty regime.
