All clay contains minerals, and these are what increases circulation and makes your skin glow. Clay also exfoliates to remove dead skin cells, so your skin is healthy looking and glowing after a facial. Last week, I taught you how to make a clay mask. You can read that here. The directions are the same for all types of clay, so choose the kind that works best with your complexion.
Pink clay -- also called rose clay -- is excellent for normal to dry skin. It removes dead skin cells and cleans your face while it improves circulation.
White clay is very mild, so use this type if you have sensitive skin. Unlike other clays, it doesn't pull oil from your skin, so it won't dry out your skin.
Yellow clay also does not pull oil from your skin, but it does exfoliate. It is great for dry or sensitive skin.
