How it works
The All Day Vitamin VC-IP 1.0 Firming Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named sixth on its own ingredient list. The same list carries Allantoin, Adenosine and Bakuchiol, so the active is not the only thing on it worth naming. How much of the Niacinamide 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 JUMISO sells in Korea, Niacinamide and all.

Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named sixth.
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. It is named twelfth on this serum's list, alongside Niacinamide.
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 fourteenth on this serum's list, beside Niacinamide.
Bakuchiolactive
Bakuchiol is a compound from the babchi seed, used as a plant-derived alternative to retinol. It is oil soluble, stable in daylight and does not carry retinol's acclimatisation period, which is why sensitive-skin formulas choose it. It is named sixteenth on this serum's list, alongside Niacinamide.
Alpha-Arbutinactive
Alpha-Arbutin is a plant-derived compound, related to the sugar-bound form found in bearberry, used for the look of dark spots and uneven tone. It is stable in water and works at skin-friendly pH. It is named seventeenth on this serum's list, alongside Niacinamide.
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 Niacinamide and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Niacinamide 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 Niacinamide?
Allantoin, Adenosine and Bakuchiol. The order they are printed in on this serum's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Alpha-Arbutin, Ascorbyl Tetraisopalmitate and Tocopherol.

How to use
- Apply it on damp skin straight after toner, which is when a light fluid travels the furthest.
- Two pumps cover a face, pressed in with flat palms so nothing is dragged across the cheeks.
- Follow with a cream once the surface has turned tacky, which usually takes under a minute.
- Avoid layering three treatment serums at once, because a crowded treatment slot is where pilling and stinging start.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Niacinamide on the list.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Niacinamide rather than to three changes at once.

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic Bakuchiol is often used as a gentler alternative to retinol. It may help your skin look smoother and reduce the appearance of wrinkles.

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.
