Kaolin is derived from the Chinese word Gao-ling, meaning “high ridge”  and a reference to a  Chinese village near Jingdezhen in southeastern China's Jiangxi Province. Kaolin clay is a soft and unusually white natural clay produced by the weathering of  aluminum silicate.  This clay is the most widely used clay in the cosmetic and beauty industry today. It is known as the mildest of all the clays and can be used on very sensitive skin types.  Kaolin Clay is often found in soaps, scrubs, poultices, deodorants, facial powders, masks, and most dry and all wet cosmetics. Since it does not draw oil like some of the other clays, it is also very useful for people with naturally dry skin. In many parts of the world China White clay, yet another name for Kaolin, is colored pink-orange by iron oxide.  This is called Pink Kaolin Clay.  Still more mild than other clays, this Pink Kaolin is a little more detoxifying than its partner White Kaolin Clay.

Note: Pink Kaolin Clay can leave some natural pigments behind on the skin. Therefor it is best to use at night when the skin will naturally absorb some of the left behind pink residue.

One is iron oxides and the second is decomposed plant material. Due to the decomposed plant material this clay should always be very green to green, never a dull grey. Unlike other clays were the key ingredients work in symbiosis with one another, many elements within the French Green Clay work on their own accord. Each element is responsible for working the outer skin layers in its own unique way.  This clay is highly absorbent and literally "drinks" the toxins from the skin.  It pulls vast amounts of toxic particulates and impurities (not to mention dust, oils, and make-up)  from the pores, while toning and bringing fresh blood to the damaged and healthy  skin cells alike.  This is a great revitalizer for the complexion, helping sustain that natural health-filled glow.
