Pearl powder is a finely milled calcium carbonate-based material derived from mollusk shells or cultured pearls, used in cosmetics for its conditioning, mild exfoliating, and perceived brightening properties. It also contains trace amino acids and minerals, though evidence for significant clinical efficacy is limited.
