COSRX Advanced Snail 96 Mucin Power Essence
At a glance
Summary
COSRX Advanced Snail 96 Mucin Power Essence scores 80/100. The hero ingredient is 96% Snail Secretion Filtrate — a clinically-studied source of glycoproteins, glycolic acid, peptides, hyaluronic acid, copper peptides, and zinc that supports barrier repair, post-acne healing, and hydration. The carrier is exceptionally short for an essence: betaine, butylene glycol, sodium hyaluronate, panthenol, allantoin, and pH adjusters. No fragrance, no essential oils, no parabens, no alcohol. Two minor cautions: sodium polyacrylate (a synthetic polymer used as a thickener) and phenoxyethanol preservative. K-beauty cult product with strong dermatology backing; very well tolerated by sensitive skin including post-procedure.
Key ingredients 12
Snail Secretion Filtrate (96%)Very Good
The active hero ingredient. A complex of glycoproteins, glycosaminoglycans, glycolic acid, copper peptides, zinc, allantoin, and hyaluronic acid harvested ethically (snails are placed on mesh in a low-stress environment and the secretion is collected). Multiple peer-reviewed studies show it accelerates wound healing, improves post-acne marks, and supports barrier function.
