Rhassoul clay is an ancient clay that comes from deep below the Atlas Mountains in Morocco. Although it is difficult to obtain from the deep clay beds, it has been used for centuries by the people of Rome and Egypt. Rhassoul clay is rich in minerals such as Silica, Magnesium, Iron, Calcium, Potassium and Sodium. It helps detoxify the skin while it exfoliates gently. Rhassoul clay is used by the finest spas around the world.
