I'm honestly so impressed with the results with the pore strips when I used them. My skin was clogged and pores were screaming to be opened. It wasn't painful at all and there were no red marks left behind when I removed the strip. It's easy to use and it REALLY really works. My friends were asking why my nose is so shiny (meanwhile back at the ranch I have my own face and beauty spa at home ?) I'm super happy with the over all results with all of the Bioré products. Absolutely Amazing!!!
