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. The name on the box points at it, and it is named fifth on this serum's own ingredient list.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named sixth on this serum's list, alongside Snail Secretion Filtrate.
Sodium DNAactive
Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to. The panel names it sixteenth on this serum's list, beside Snail Secretion Filtrate.
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. It is named forty-fifth on this serum's list, alongside Snail Secretion Filtrate.
Acetyl Tetrapeptide-11peptide
Acetyl Tetrapeptide-11 is a four-amino-acid peptide used for the look of firmness, and it is the usual partner to acetyl tetrapeptide-9. It is named ninth on this serum's list, alongside Snail Secretion Filtrate.
How to use
- Use this serum AM and/or PM, as the serum step, after toner or essence and before moisturizer. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum 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 serum or a US version?
The Korean-market one, Snail Secretion Filtrate and all. We match this serum 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?
Niacinamide, Sodium DNA and Adenosine. The order they are printed in on this serum'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: Acetyl Tetrapeptide-11, Palmitoyl Pentapeptide-4 and Palmitoyl Tripeptide-1.

How it works
The Ultra S4 Snail Serum is a 70ml serum, used after toner and before moisturizer, morning and evening. The humectant it is built around is Snail Secretion Filtrate, named fifth on its own ingredient list. The same list carries Niacinamide, Sodium DNA and Adenosine, 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 serum format rather than by the list alone. This is the Original Korean Formula, the serum DEWYTREE sells in Korea, Snail Secretion Filtrate and all.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Snail Secretion Filtrate on the list.
- Introduce this serum 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.
