Snail mucin
Hydrates and leaves skin feeling soft and repaired.
What the evidence says
Pleasant hydrator with early human evidence; lacks robust replication.
How to use it
Morning and night, after cleansing (and toner, if you use one) and before moisturizer. Its signature viscous texture absorbs best patted onto slightly damp skin.
What it pairs with
Compatible with everything: niacinamide, retinoids, exfoliants and vitamin C. It works well as a hydrating cushion in routines with strong actives.
Frequently asked questions
What does snail mucin actually do?
It's mostly a hydrator and soother: it contains glycoproteins, natural hyaluronic acid and small amounts of glycolic acid. The soft, "repaired" skin feel is real; the deep-regeneration and anti-aging promises, however, still lack robust evidence.
How is it harvested? Are snails harmed?
The main Korean producers (like COSRX's suppliers) collect the secretion by letting snails roam over mesh in dark, calm environments, without aggressive stimulation. Snails aren't killed or injured — but it's obviously not a vegan ingredient.
Does it help with acne marks?
It can help indirectly: well-hydrated, calm skin repairs better, and there's early human evidence on wound healing. But for pigmented marks there are actives with more direct evidence: niacinamide, azelaic acid or vitamin C.
