An important step in maintaining healthy skin is to draw out the impurities and toxins on a regular basis. Mud (or magnetic clay) has been used for centuries as a natural way to help the body release toxins through your skin. The mud is magnetically charged "negative" and toxins in your skin and body are magnetically charged "positive". The mud's magnetic charge is activated when it becomes wet, so when it's applied to the skin it attracts toxins to it and draws them out of your body.
