To be honest, I have never had severe blackheads on my nose, the regular cleansing helps me to keep them at bay, but i was dying to test out anti-blackhead products, so I made my best friend to become my guinea pic this time lol
We applied the nose strip after wetting it (and making my friend to spend some time in sauna to loosen up his pores), and you know what, this little one did its job! Even though I had to apply other products in order to shrink his pores and prevent from forming new camedons, i think for its price, this patch does miracles
