How it works
The Advanced Snail 96 Mucin Power Essence is a 50ml essence, used after toner and before serum, morning and evening, on damp skin. The humectant it is built around is Snail Secretion Filtrate, named first on its own ingredient list. The same list carries Allantoin, Arginine and Sodium Hyaluronate, so the humectant is not the only thing on it worth naming. How much of the Snail Secretion Filtrate stays on the skin, and for how long, is decided by the essence format rather than by the list alone. COSRX sells this Snail Secretion Filtrate essence in Korea, and this is that version.
Key benefits

- Allantoin on the same list, an active
- Arginine on the same list, an amino acid
- Sodium Hyaluronate and Ethyl Hexanediol on the same list, humectants
- Panthenol further down the same list
- Snail Secretion Filtrate named first on the manufacturer list printed on this page
Key actives
Snail Secretion Filtratehumectant
Snail Secretion Filtrate is the mucin a snail produces, filtered for cosmetic use, and it is the ingredient the Korean snail category is built on. It carries glycoproteins, hyaluronic acid and glycolic acid, and it is used for hydration and a smoother-looking surface. It is the entry this essence is named after, and the list carries it.
Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. It is named eighth on this essence's list, alongside Snail Secretion Filtrate.
Arginineamino acid
Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster. The panel names it twelfth on this essence's list, beside Snail Secretion Filtrate.
Sodium Hyaluronatehumectant
Sodium Hyaluronate is the salt of hyaluronic acid, and it is what most products labelled hyaluronic actually contain. The salt dissolves more readily and the molecule is smaller, so it sits in the outer layer of skin rather than only on top of it. It is named seventh on this essence's list, alongside Snail Secretion Filtrate.
Ethyl Hexanediolhumectant
Ethyl Hexanediol is a glycol that hydrates and makes a formula less hospitable to microbes, the same double role 1,2-hexanediol plays. It is named ninth on this essence's list, alongside Snail Secretion Filtrate.

Where does this essence go in my routine?
After toner and before serum, morning and evening, on damp skin. Anything thinner than an essence goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Snail Secretion Filtrate and not three changes at once.
What else is on the list besides Snail Secretion Filtrate?
Allantoin, Arginine and Sodium Hyaluronate. The order they are printed in on this essence's panel is the order on the box, so you can see where Snail Secretion Filtrate sits relative to them. Further down the same panel: Ethyl Hexanediol and Panthenol.

How to use
- Use the Advanced Snail 96 Mucin Power Essence after toner and before serum, morning and evening, on damp skin.
- A small palmful, pressed over the face and neck in two passes rather than rubbed in.
- Toner first, this second, then your serum and moisturizer. It is the layer that thins the ground so the step above it spreads instead of sitting.
- Twice a day, every day. Do not use it in place of your moisturizer; an essence is a water layer, not the lid on top of one.
Worth knowing
- Snail secretion filtrate is animal-derived, so this is not a vegan formula.

The hyaluronic acid and peptides in snail mucin may stimulate the production of collagen and elastin.
Hadley King, MDClinical instructor of dermatology, Weill Medical College of Cornell, Women's Health Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.

Hyaluronic acid helps bind water to collagen, which traps water in the skin. That helps make the skin more plump and full-looking.
