I liked the mask. I've only used it once thus far, but it seemed to do a pretty good deep cleansing.
My face definitely needed moisturizer after using the mask, but it didn't seem way over-dried.
My one comment would be that there should be a warning or note informing the user that it WILL sting first! :) After I felt the stinging (some say tingling) sensation, I googled the mask, to make sure that it wasn't a problem with my skin reacting. Apparently that's just the product. It was a little startling at first though.
Otherwise, great mask!
