With these strips i found the best way to get a good result was that i had to steam and prep the skin first which was a bit of a long process. The end result after all that still wasn't great and made me feel like i wasted my time. The black residue afterwards is also a pain to wash off. I prefer the ultra deep cleansing ones instead.
I find it very hard to get nose pore strips as I find they stick but never bring anything out. The biore strips are one of the better ones I've tried. I'd say it's more an 80/20 sprite. 80% I find it does their jobs and 20% I find they don't bring anything up, which i find a little strange. When they do work they work great and do clean your nose pores. I do find they can be a little expensive, especially as you only get 6 strips but part from that I would recommend to give them a try!
This product works rather well however its not perfect. I have however yet to find a nose strip thats perfect, and this is the best I have used. It seems to remove a lot of built up grease and skin from the pores well, however can occasionally leave a residual residue which isn't great, so I usually have to we wipe over the nose when I am finished. Generally good but a bit pricey for only 6 strips. If its on offer, GRAB IT, if not...maybe wait a while till it is.
