Bentonite is a mineral rich clay used for centuries to maintain healthy skin tone and texture. It can help remove impurities resulting in healthier skin that is clean and clear of harmful debris and dirt. 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. Clays are a popular feature at many health spas today, and are widely used as a means to promote healthy, youthful looking skin.
