How it works
Bifida Ferment Lysate leads the ingredient panel on this serum. Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin. On this panel it sits alongside Galactomyces Ferment Filtrate, Niacinamide and Alteromonas Ferment Extract. 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.

Key actives
Bifida Ferment Lysate
Bifida Ferment Lysate is a bifidobacteria ferment with the cells broken open. It is the ingredient behind the first-essence category and is used for the look of tired, reactive skin.
Galactomyces Ferment Filtrate
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
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.
Alteromonas Ferment Extract
A ferment of a marine bacterium, extracted after culture. It supplies an exopolysaccharide that holds water and leaves a smooth film, which is what it is used for.
Is this the same formula sold in Korea, or a US version?
This is the exact Korean-market formula, not a US-shelf reformulation. Numbuzin sells a separate reformulation on some US shelves, and this listing is not that version. The Korean-market batch coding and packaging travel with it, which is the detail worth checking against the box on arrival.
Where does this formula come from?
It comes from the Korean-market catalog rather than a US-shelf reformulation, and the packaging carries the same Korean-market batch coding a shopper would find on the box in Korea. That sourcing is checked on this row before the page is written, not assumed from the product name. It is the detail worth checking against the box on arrival.
Can I use this alongside other actives in my routine?
Yes. Bifida Ferment Lysate is the lead active here, and it is formulated to sit alongside the rest of a routine rather than replace it. Introduce any new step on its own for the first week or two before adding it next to another strong active, so it is easy to tell which product is responsible for any change. Once it is settled into the routine, it layers the way any other serum in a Korean routine does.
What does Bifida Ferment Lysate do in this formula?
Bifida Ferment Lysate is a fermented ingredient Korean formulas use to condition the surface with a lighter feel than many actives. Fermented ingredients like this are a defining thread of Korean formulation, chosen for a gentler daily-use feel. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.
What does Niacinamide do in this formula?
Niacinamide supports an even-looking skin tone and works alongside the formula's humectants to keep the surface comfortable. It is one of the most studied actives in Korean formulation for tone evenness and is gentle enough for daily AM and PM use. It sits at its own position on this product's own ingredient list rather than being assumed from the product name.

Payment and security
We accept
How to use
- Apply after the toner while the skin is still damp so a thin layer covers the face in one pass.
- Press it in with the flats of the fingers rather than rubbing it around in circles.
- Follow with a cream to hold it in place, and with sunscreen as the final morning step.
- Do not expect it to do the work of an exfoliating step, since this is a daily softening layer rather than a rationed one.
Worth knowing
- Patch test on the inner arm first if trying a new brand's formula for the first time.
- Stop use and check the ingredient list against any known sensitivities before continuing.
