Natural clays are making a huge comeback in the natural cosmetic. More and more they are being incorporated into cosmetic formulas. Mineral clays are a natural raw material that is versatile in use and ideal for sensitive skin.
Clays were formed during the last ice age, however, today they are mined at depths between 10 and 30 metres. Essentially, clay is made up of layers of loam that have been formed over the course of several millennia.
Clays are rich in various minerals. Depending on where they are mined, they may contain magnesium, calcium, iron, silica, copper and a whole range of other substances.
In order to be used for cosmetic products, clays must be natural, germ-free and biologically sound. As a result, they are dried in special ovens or in the sun after extraction. This process kills any germs and the clay is pasteurised through exposure to heat.
The unique powers of this soil have been known since ancient times. In ancient Egypt, for example, clay was used for antiseptic mud baths and Hippocrates, one of the most outstanding figures in the history of medicine, also recommended it for internal use.
