How it works
The Vita Drop Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named fourth on its own ingredient list. The same list carries 3-O-Ethyl Ascorbic Acid, Ascorbic Acid and Biosaccharide Gum-1, 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 KAINE 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 fourth.
3-O-Ethyl Ascorbic Acidantioxidant
3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable. The panel names it thirty-sixth on this serum's list, beside Niacinamide.
Ascorbic Acidantioxidant
Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone. The panel names it thirty-ninth on this serum's list, beside Niacinamide.
Biosaccharide Gum-1polysaccharide
Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel. The panel names it twenty-second on this serum's list, beside Niacinamide.
Hippophae Rhamnoides Fruit Extractplant extract
Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract. It is named sixteenth 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?
3-O-Ethyl Ascorbic Acid, Ascorbic Acid and Biosaccharide Gum-1. 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: Hippophae Rhamnoides Fruit Extract, Coptis Japonica Root Extract and Melia Azadirachta Leaf Extract.

How to use
- Apply a small amount to cleansed, toned skin, pat in gently, then follow with a moisturizer.
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.
