I was a little scared in using this mask, because I read a few post that said that it dehydrate the skin, but that didn't happened to me in an agresive way, I have oily to combination skin and this product does wonders in my T zone, I think it really open and deeply cleans my pores. I use this product once a week, because the city were I live has cmplicated polluted air conditions and my skin produces a lot of oil, so I need to deeply clean my pores to avoid acne, this product has been great with my skin, everytime I use it I feel my skin the cleaner it can be, beside, the bubble effect makes this mask a really fun step in my skincare routine <3
