What does snail mucin do for skin?

Snail Mucin (Snail Secretion Filtrate) is packed with proteins, hyaluronic acid, and glycoprotein enzymes that help hydrate, repair skin damage, reduce fine lines, and improve overall skin texture and radiance.

Is COSRX Snail Mucin safe for sensitive skin?

Yes. It has passed both a Skin Irritation Test and a Human Repeat Insult Patch Test (HRIPT). However, a patch test is still recommended before applying to the face.
