Key ingredients

Snail secretion filtrate 96%

Snail mucin naturally carries glycoproteins, hyaluronic acid, elastin and antimicrobial peptides. That mix supports the skin's renewal cycle and helps fade the marks left behind by breakouts. The 96% concentration is the single biggest thing that sets this essence apart.

Allantoin

A plant-derived soothing ingredient that conditions skin and takes the edge off irritation. It helps steady a compromised barrier and is gentle enough for sensitive skin.

Sodium hyaluronate

The salt form of hyaluronic acid. Its smaller molecular size lets it sink in deeper, where it helps draw in water and hold onto it.

Acetyl glucosamine

An ingredient that helps smooth texture and ease the look of pigmentation. It also acts as a precursor that supports the skin's own hyaluronic acid synthesis.

Watch-outs

Phenoxyethanol (preservative)

There is no fragrance, alcohol or paraben here, so it stays low on irritation. Phenoxyethanol is an FDA-approved preservative that is safe for most people.

Frequently asked questions

Which skin types is a snail mucin essence good for?
It is especially helpful for skin that is slow to recover after breakouts, skin with uneven texture, and skin that runs dry and sensitive. It is a good fit when you want hydration and soothing at the same time.
Does it have a smell?
There can be a faint scent that comes with snail mucin itself, but it is very mild. No artificial fragrance is added.
Can I use it every day?
Yes. Apply it morning and night after cleansing, at the step right after toner. Spread a thin layer and give it a moment to absorb.
Is it vegan and cruelty-free?
Because it uses snail secretion, it is not a fully vegan product. COSRX says it collects the mucin in a way that does not harm the snails, but it still does not meet strict vegan standards.
