As a frequent sufferer of pesky blackheads, when I first heard about Biore Ultra Deep Cleansing Pore Strips I was intrigued. After asking around, I had found mixed reviews but decided that I had to try them for myself. First you need to start by washing your face, but do not dry, the strips need to be applied to a wet nose or else they will have a problem sticking to you. The packaging says to leave the strip on for 10-15 minutes, I chose to leave it on for the full 15. I've heard complaints that they can be painful to take off, but I didn't experience this. Perhaps others were leaving the strips...
