I was very impressed with these strips & it does what it claims to do. After I gently peeled the strip off, I could literally see the extracted impurities on the strip as it is black. White heads were more visible on the strip. The results are immediate and my nose was smooth; silky & my large pores appeared tighter. I was left with a slight black residue from the charcoal but a gentle wipe with a facecloth removes it easily. I love the refreshing mint scent it has.
