I love love love nose strips! I use them at least once every two weeks, and I've tried so many different brands. This one is good, but not my favourite... After I took it off there were little pieces of the mask still on my skin, and a grey residue was left all where it had been. I know it's easy to just wash it off but other charcoal brand ones I've used have NOT done this, and they're cheaper in price. So for that reason I won't buy again.
