MoM is actually sold as an antacid/laxative, in the pharmacy section of most drugstores. It can be used, however, as a fantastic oil-absorbing mask, or even a mattifier under makeup (diluted with water). All you need is any unflavored version. Apply to the face with fingers, cotton, or a brush in a thick layer. Let dry for about 10-15 min, then rinse off! Your face will be smooth and oil-free.
