Bentonite, also known as montmorillonite or fuller’s earth, is a natural clay that’s used as a facial mask to help remove impurities, excess oil, and dirt, resulting in healthy skin that’s clean and clear of harmful debris. Historically used to maintain healthy skin tone and texture due to its high content of trace minerals, Bentonite Powder can also be used as a body mask to help dry up excess oil and remove impurities from other potential problem areas besides the face.
