Treat yourself to a spa treatment with this clay mask. This particular clay is perfect for oily skin, and is easy to mix. Just add a small amount of the clay to a bowl or cup and add just the right amount of water to it to get the paste into the consistency of buttermilk. Stir it with a plastic or wooden spoon (DO NOT USE A METAL SPOON!). Once you get it to the right consistency, then spread in over your face, taking care to avoid your eyes and wait until it dries and hardens. Afterwards, wash your face off with warm water. It is recommended to use a facial moisturizer afterwards.
