Key actives
Galactomyces Ferment Filtrateferment
Galactomyces Ferment Filtrate is a yeast ferment filtered clear, the ingredient that made the Korean and Japanese essence category. It carries amino acids, vitamins and organic acids and is used for the look of dullness and rough texture. It is the entry this serum 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 sixth on this serum's list, alongside Galactomyces Ferment 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 thirteenth on this serum's list, beside Galactomyces Ferment Filtrate.
Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named fourteenth on this serum's list, alongside Galactomyces Ferment Filtrate.
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. The panel names it fifteenth on this serum's list, beside Galactomyces Ferment Filtrate.
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 Galactomyces Ferment Filtrate and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Galactomyces Ferment 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 Galactomyces Ferment Filtrate?
Niacinamide, Adenosine and Dipotassium Glycyrrhizate. The order they are printed in on this serum's panel is the order on the box, so you can see where Galactomyces Ferment Filtrate sits relative to them. Further down the same panel: Allantoin, Aspalathus Linearis (Rooibos) Extract and Glycyrrhiza Glabra (Licorice) Root Extract.

How it works
The Rose Galactomyces Synergy Serum is a 50ml serum, used after toner and before moisturizer, morning and evening. The ferment it is built around is Galactomyces Ferment Filtrate, named first on its own ingredient list. The same list carries Niacinamide, Adenosine and Dipotassium Glycyrrhizate, so the ferment is not the only thing on it worth naming. How much of the Galactomyces Ferment 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 IUNIK sells in Korea, Galactomyces Ferment Filtrate and all.
How to use
- After toner, before moisturizer.
- Apply a few drops over the face and neck.
- Follow with a moisturizer.

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.
