How it works
The Galactomyces 95 Tone Balancing Essence is a 100ml essence, used after toner and before serum, morning and evening, on damp skin. The ferment it is built around is Galactomyces Ferment Filtrate, named first on its own ingredient list. The same list carries Niacinamide, Allantoin and Adenosine, 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 essence format rather than by the list alone. This is the Original Korean Formula, the essence COSRX sells in Korea, Galactomyces Ferment Filtrate and all.
Key benefits
- Galactomyces Ferment Filtrate, the ferment this essence is built around
- Niacinamide, Allantoin and Adenosine on the same list, actives
- Panthenol on the same list, a humectant
- Sodium Hyaluronate and Ethyl Hexanediol further down the same list
- Galactomyces Ferment Filtrate named first on the manufacturer list printed on this page
- Original Korean Formula, the essence sold on Korean shelves
COSRX Galactomyces 95 Tone Balancing Essence
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 Galactomyces Ferment Filtrate and not three changes at once.
Is this the Korean-market essence or a US version?
The Korean-market one, Galactomyces Ferment 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 Galactomyces Ferment Filtrate?
Niacinamide, Allantoin and Adenosine. The order they are printed in on this essence'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: Panthenol, Sodium Hyaluronate and Ethyl Hexanediol.

12 of 12 explained
- Galactomyces Ferment Filtrate ferment
- 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.
- Niacinamide active
- Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is used at roughly 2 to 5 percent for the look of uneven tone and visible pores, and it is water soluble, stable and comfortable beside almost every other active, which is why it turns up in so many lists.
- Panthenol humectant
- Panthenol is pro-vitamin B5: skin converts it to pantothenic acid. It is a humectant that holds water and leaves skin feeling soft and less tight, and it is one of the ingredients formulators reach for when a formula also contains something harsh.
- Glycerin humectant
- Glycerin is the most used humectant in skincare. It draws water into the outer layer of skin and holds it there, and it is one of the very few ingredients whose hydrating effect is settled science rather than marketing. Higher amounts feel tacky, which is why it is usually blended.
- 1,2-Hexanediol humectant
- 1,2-Hexanediol is a glycol used for two reasons: it holds water like glycerin, and it makes a formula harder for microbes to live in, so less traditional preservative is needed. Korean formulas use it heavily for that second reason.
- Butylene Glycol humectant
- Butylene Glycol is a small glycol that does two jobs at once: it holds water in the top layer of skin and it dissolves plant extracts and actives that plain water cannot. It also thins a formula, which is why watery Korean essences lean on it.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- Sodium Hyaluronate humectant
- 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.
- Allantoin active
- 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.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- Ethyl Hexanediol humectant
- Ethyl Hexanediol is a glycol that hydrates and makes a formula less hospitable to microbes, the same double role 1,2-hexanediol plays.
- Adenosine active
- 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.

How to use
- Use the Galactomyces 95 Tone Balancing Essence after toner and before serum, morning and evening, on damp skin.
- A small palmful, pressed over the face in two passes rather than rubbed around.
- Toner first, this second, then serum and moisturizer while the layer underneath is still damp.
- Twice a day, every day. Do not swap your toner out for it; the two are different jobs in the same part of the routine.
