I have sensitive combination skin and use that mask about 3 times a month, give or take. I shower, put the mask on for about 10 minutes, then remove it and rinse my skin with cold water to shut up my pores. I immediately moisturize, since it is a more drying mask. Personally, I like the temporary improvements it provides; it makes my skin really smooth and clean-looking for a few days afterward.
A huge tub of the stuff costs about $5-6 and the tube is about half that, so if you don't like it, it's not a huge loss.
