French Green Clay, also known as Sea Clay or Illite Clay, is a highly regarded mineral clay rich in various beneficial elements such as magnesium, calcium, and silica. Its distinctive green hue comes from iron oxides and decomposed plant matter. Recent studies have suggested potential benefits for skin conditions like rosacea and eczema. The clay is mined, processed, and used to make products like a facial bar, effective at removing impurities and delivering minerals to the skin. New products, such as the Sophisticated Man Soap, continue to explore its application.
