The mask was incredible, at first I was a bit skeptical that if will work effectively in "ONLY ONE MINUTE" but it really worked miracles and it was very effective even in a minute. This mask is time effective, especially if you are student or employee and you have to go to school/ work, you don’t have to spend a lot of time on your face as the mask works well in only a minute. I apply the mask twice a week and I have seen change over the 3 weeks of testing out the product. The oiliness from my face has reduced.
