Royal Black Snail Ampoule is Dr.G's ampoule serum (30ml), built around Snail Secretion Filtrate and Squalane.

How it works
The Royal Black Snail Ampoule is a 30ml ampoule, used after toner and before moisturizer, morning and evening. The humectant it is built around is Snail Secretion Filtrate, named first on its own ingredient list. The same list carries Niacinamide, Adenosine and Zymomonas Ferment Extract, 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 ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule Dr.G sells in Korea, Snail Secretion Filtrate and all.

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 ampoule is named after, and the list carries it.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named eighth on this ampoule's list, alongside 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. The panel names it twentieth on this ampoule's list, beside Snail Secretion Filtrate.
Zymomonas Ferment Extractferment
A ferment of zymomonas, the bacterium behind agave based fermentation. It supplies sugars, peptides and organic acids and is used as a conditioning ferment. It is named thirty-fifth on this ampoule'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 thirty-third on this ampoule's list, alongside Snail Secretion Filtrate.
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule 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 ampoule or a US version?
The Korean-market one, Snail Secretion Filtrate and all. We match this ampoule to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
Does this ampoule contain fragrance?
Yes. The ingredient list names Fragrance and Parfum. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this ampoule is not the one.
What else is on the list besides Snail Secretion Filtrate?
Niacinamide, Adenosine and Zymomonas Ferment Extract. The order they are printed in on this ampoule'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, Glycosphingolipids and Cholesterol.

How to use
- Use it twice a day after the watery step, on a clean face and before any cream.
- Warm a small amount between the fingertips first, then press it over the cheeks, forehead and chin.
- Give it thirty seconds to settle before the next layer goes on, which is what keeps anything from balling up.
- Avoid applying it to skin that is completely dry after a long gap, since a thin layer spreads much further on damp skin.
Worth knowing
- Patch test this ampoule on a small area and wait a day before using it more widely, especially with Snail Secretion Filtrate on the list.
- This list names Fragrance and Parfum, so skip it if fragrance components are something you avoid.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
