What it is
Snail mucin, technically snail secretion filtrate, is a K-beauty staple ingredient used for hydration and repair, sold at a range of concentrations from a supporting presence up to a concentrated 96% headline dose.
What the evidence says
Used for its hydrating, repair-supporting role, with a long track record and large accumulated user base in K-beauty specifically. Concentration varies meaningfully between products: COSRX confirms a maximized 96% concentration as its headline active, while Beauty of Joseon's Revive Serum uses snail secretion filtrate at an undisclosed, likely lower concentration alongside five other actives, ginseng, niacinamide, adenosine, centella, and sodium hyaluronate.
Who it's for
Anyone wanting a well-established, long-track-record hydration and repair ingredient, from a light supporting role to a concentrated primary active.
Worth knowing
Vegans and those avoiding animal-derived ingredients, since snail mucin is an animal byproduct.
