Kaolin, also known as White Clay, is one of the lightest of all the clays making it especially suitable for sensitive and dry skin types. It is used in medicine, ceramics and even toothpaste! It has even been used in some organic farming as a spray to deter insect damage.
Clays are minerals from the earth that result from the degradation of mineral rocks. Ancient Egyptians used clay as both medicine and cosmetics, as it is believed to be able to treat an upset stomach and animals search for clay to cover wounds, so really it is rather useful!
