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.
Adenosineactive
Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated. The panel names it twelfth on this essence's list, beside Snail Secretion Filtrate.
Copper Tripeptide-1peptide
Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines. The panel names it forty-first on this essence's list, beside Snail Secretion Filtrate.
Glutathioneantioxidant
Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it. It is named twenty-fifth on this essence's list, alongside Snail Secretion Filtrate.
Ceramide NPbarrier lipid
Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy. It is named forty-second on this essence's list, alongside Snail Secretion Filtrate.
How to use
- Use this essence AM and PM, as the step after toner and before serum. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.
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.
Is this the Korean-market essence or a US version?
The Korean-market one, Snail Secretion Filtrate and all. We match this essence to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Snail Secretion Filtrate?
Adenosine, Copper Tripeptide-1 and Glutathione. 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: Ceramide NP, Hydrolyzed Collagen and Aloe Barbadensis Leaf Extract.

How it works
The ULTRA S4 Snail Essence Water is a 150ml essence, used after toner and before serum, morning and evening, on damp skin. The humectant it is built around is Snail Secretion Filtrate, named sixth on its own ingredient list. The same list carries Adenosine, Copper Tripeptide-1 and Glutathione, 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. This is the Original Korean Formula, the essence DEWYTREE sells in Korea, Snail Secretion Filtrate and all.
Worth knowing
- Patch test this essence on a small area and wait a day before using it more widely, especially with Snail Secretion Filtrate on the list.
- Introduce this essence on its own for the first week, so anything your skin does is traceable to the Snail Secretion Filtrate rather than to three changes at once.
