French Green Clay
What is French Green Clay?
French Green Clay is a naturally occurring sedimentary mineral sourced from ancient marine deposits in France's quarries. Its vibrant green color comes from iron oxides, with a composition dominated by illite alongside montmorillonite, kaolinite, and trace elements like silica, magnesium, calcium, potassium, and aluminum. In cosmetics, it falls under absorbent powders, primarily used in facial masks, cleansers, and gentle exfoliants. When mixed with water, it expands into a paste that adheres to sebum, dirt, and pollutants on the skin, aiding their removal upon rinsing. The fine texture enables mild mechanical exfoliation, while inherent minerals leave skin feeling refreshed and balanced after application.
