I am very happy with this mask. I haven't noticed great changes to my skin, but I have noticed, with 2 uses once a week, my skin is a little more plump and awake, some very fine lines have diminished. And I know is this mask because it is the only new element in my routine, so I believe it will become part of my weekly skincare routine. I will say that on the 8th minute I did start feeling a tingling/stinging sensation on my face, that when I took the mask off, my face felt firmer, but I haven't noticed no big changes, but then again it isn't one of my skin problems.
