What it does
Humectant and repairative secretion from snails, rich in glycoproteins and hyaluronic acid.
Snail secretion filtrate — more commonly called snail mucin — is the ingredient that built the COSRX brand. The Advanced Snail 96 Mucin Power Essence has ranked as Amazon's #1 beauty bestseller across multiple years, driven by repeat purchase and strong tolerability on reactive skin. Filtered from ethically farmed snails, the secretion contains natural hyaluronic acid, allantoin, glycolic acid, proteoglycans, and copper peptides. The combination provides humectant hydration, mild exfoliation, and surface-repair support — unusual to find in a single natural ingredient. Concentration matters: common labels include 92%, 96%, and 97% secretion filtrate, and products with these disclosed percentages deliver meaningfully more benefit than formulas where mucin sits low on the INCI. Snail mucin layers smoothly under any other skincare step and is extremely well tolerated — suitable for teens through mature skin, and during pregnancy.
