Snail Mucin

Snail mucin in cosmetics is usually listed as snail secretion filtrate. It is a processed mixture containing water-soluble glycoproteins, sugars and other components rather than a single active molecule, so composition can vary between suppliers and products.

Small clinical studies and broader research on snail-derived materials suggest hydration, conditioning and recovery-related potential, but the evidence base is much smaller than the ingredient's popularity in K-beauty might imply. Its most defensible cosmetic role is as a hydrating and skin-conditioning ingredient.
