I'm very excited about the new mask from Somethinc. the first impression after using it for the first time I felt there was a stinging effect when the mask was applied to the face but only for a few seconds after that it was gone. This mask is enough to wear for 10 minutes and immediately rinsed with water until clean. The results I get face look fresh, clean and moist. the brightening effect has not been seen, maybe because it is still in use 1 time. I hope it fits if I use it for a long time.
