Formed from water-eroded rocks in Earth's crust, clay primarily consists of silica, alumina salts, iron, magnesium, and other essential minerals. Variations in these mineral proportions create distinct colors. Green clay draws its hue from oxidized iron and organic matter. Red clay results from highly oxidized iron without organic matter. Yellow clay shines with copper and zinc. White clay, highly purified, features minimal minerals and a neutral pH, rendering it exceptionally gentle.
Green clay, the most popular choice, suits combination to oily skin with its mineral-rich, anti-inflammatory benefits. Available as chunks, powder, or ready-to-use paste. Red clay, mineral-dense especially in iron, boosts circulation, soothes sensitive or blotchy skin, and detoxifies. Sold mainly as powder. White clay offers ultimate gentleness—less absorbent due to low mineralization, with silica for anti-wrinkle effects. Ideal for dry, mature skin to restore glow and for hair care.
Blends and natural variants expand options. A mix of ¾ white clay and ¼ red yields gentle pink clay that revitalizes and purifies sensitive skin. Purple clay mirrors white clay's mild traits. Yellow clay's zinc and copper excel at exfoliating combination to oily skin and gentle masks for normal to sensitive types, thanks to low iron. Rhassoul, a Moroccan hammam staple, deeply cleanses oily or acne-prone skin and adds shine and volume to oily or fine hair.
