The main ingredient to expensive masks is bentonite clay. Kitty litter with no added ingredients is nothing more than bentonite clay. Here is a recipe you can make that will give you a professional mask costing pennies to make.
The reason this mask works so well is when water is added to the kitty litter it changes the molecular structure and an electrical charge is produced which draws out the toxins into the clay removing them from your body. If you do not like the idea of using kitty litter for a mask you can buy bentonite clay at most health food stores.
This mask works best on oily skin with large pores. Do not use if you have dry skin.
