I bought this mask hoping it would help cleaning out my pores and getting rid of blackheads, sadly it did not work for me. This is a very unusual mask. It is black, strange color on the face then turns to a lighter grey color when it is done after 15 minutes. Well when I tried this it did not completely dry after that time so I began to wash it off with warm water. It took a bit of rubbing to remove it which I did not like and when I was done my skin did not feel clean, the pores on my nose did not seem cleaned out either. When it is drying your face feels like it is tightening up which did not bother me, the only problem was that it did not get my face feeling or looking really clean. I decided to go over my face with toner after I washed the mask off and there was still some light black reside on it. Not good at all.
