It contains two different sets of purifying strips (4 x nose strip, 2 x 2 chin and forehead strips), one is for the forhead and chin, the other for the nose. The strips are applied on clean, thoroughly wet face, then you wait for 10-15 minutes until the strip is entirely dry and you are ready to GENTLY peel it off. What happens next is fascinating, or at least to me it is, some people think it is disgusting :-}. Ideally, the contents of your pores will have stuck to the strip - let's just leave it there, the skin will be purified!
It is a good idea to wash your face again and apply a light moisturizing cream to calm the skin down, because the chances are that it will be red and irritated. The active ingredient is citric acid, so I would not recommend this product to anyone with a really sensitive or dry complexion. It works wonders on my oily skin, though.
