I really have trouble with my skin is oily with enlarged pores !! I tried creams, micellar solution, cleansing gels to get rid of those damn ugly blackheads. So I wanted to test these patches and frankly .... WAOOOUW !!! it's super simple, fast and EFFICIENT !! its really works! when you remove the strips purifying there full full of black spots of impurities and dead skin. I suggest you rinse your face with ice water which will tighten the pores !! I do it once a week and more than enough !! FOOOOONCEZ ....
