Review title is Great Mask / Gets Impurities! [SEP] This is an industrial strength mask for people with strong skin. It really takes off the top layer. I got a sample size in a monthly makeup sample subscription and purchased this after using all the sample. I use it once a week. It leaves my skin smooth and glowing. If you have thin or sensitive skin, this may not be the product for you. The peel off is mean! But the results are great.
