Resulting from the erosion by water of the rocks of the earth's crust, clay is made up mainly of silica, alumina salts, iron, magnesium and a host of other essential minerals. The variations in the proportions of these minerals give the clays their different colours. Green clay is rich in oxidized iron and organic matter, red clay owes its color to the absence of organic matter combined with the presence of highly oxidized iron and yellow clay gets its luminous color from copper and zinc. who compose it. White clay is a very washed out clay. Its lack of minerals and its neutral pH make it a very soft clay.
Green clay is the best known and the most used. Suitable for combination to oily skin, it has mineralizing and anti-inflammatory properties. It is found in the form of small pieces, powder or in a ready-to-use paste. Red clay is very concentrated in minerals, especially iron. Stimulating for circulation, it is ideal for sensitive and blotchy skin, which it soothes and detoxifies. It is most often sold in its powder form. White clay is sweetness itself. Its low mineralization (which makes it less absorbent than green clay) and its silica content (excellent anti-wrinkle) make it a treatment of choice for dry and mature skin, to which it restores a beautiful glow. Very useful clay for hair care.

Thus, a mixture of ¾ of white clay with ¼ of red clay will give an extremely gentle pink clay with sensitive skin that it revitalizes and purifies. Same principle for purple clay, which has characteristics very similar to the white clay from which it comes. Yellow clay is a product that owes its originality only to nature. Its concentration of zinc and copper gives it its color. It is a remarkable product for exfoliating combination to oily skin and its low iron content makes it perfect for masks for normal to sensitive skin. Finally, a change of scenery with rhassoul, which comes to us from Morocco where it is commonly used in hammams for skin and hair care.
