Clay powder by ESC Laboratoire is light green in color and superfine type, that is to say with a very fine particle size, easy to model and apply. It comes from French green clay deposits located at the foot of the Auvergne volcanoes. Its provenance gives it a unique structure composed of 3 complementary clays (illite, montmorillonite and kaolinite). This clay does not contain quartz. This composition has unique virtues which are characterized by a strong power of absorption and adsorption (i.e. its ability to absorb nutrients contained in the soil). This clay, which is a natural mineral, has a strong covering power and its extremely low moisture content is between 4 to 6%. Its natural composition is particularly suitable to reduce the risk of tendon engorgement after exercise. What to combine this care product with? In order to reinforce the decongestant action on congested tendons, the clay powder can be combined with a treatment of Chrysantellum Americanum whose saponosides are recognized for their benefits on blood circulation.
