Snail Mucin: K-Beauty's Most Famous (Odd) Ingredient

It sounds odd, but snail mucin is one of the best-loved K-beauty ingredients ever. Once you feel the texture, you'll understand why.

What is snail mucin?

Snail mucin, listed as Snail Secretion Filtrate, is the clear gel snails produce. It is rich in natural moisture-binding compounds, and it is filtered and purified before it goes into skincare.

• Comforts. It helps stressed skin feel soothed.
• Healthy glow. Skin looks fresh and smooth.

Who it suits

Most skin types, especially dry, dull and dehydrated skin. Not for those avoiding animal-derived ingredients.
