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 benefits
- Niacinamide, the active this serum is built around
- 3-O-Ethyl Ascorbic Acid and Ascorbic Acid on the same list, antioxidants
- Biosaccharide Gum-1 on the same list, a polysaccharide
- Hippophae Rhamnoides Fruit Extract on the same list, a plant extract
- Coptis Japonica Root Extract and Melia Azadirachta Leaf Extract further down the same list
- Ocimum Sanctum Leaf Extract and Theobroma Cacao (Cocoa) Extract further down the same list
Inside the formula
Inside the formula
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.

38 of 39 explained
- Water solvent
- Water is the base almost every serum, toner and cream is built on. It dissolves the water-loving ingredients and sets how light the finished texture feels. On an INCI list it is usually first, which only means it is the largest single ingredient by weight.
- 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.
- 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.
- 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.
- Caprylic/Capric Triglyceride emollient
- Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
- 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.
- 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.
- Limnanthes Alba (Meadowfoam) Seed Oil emollient
- Meadowfoam Seed Oil is over 95 percent long-chain fatty acids, which makes it exceptionally stable against going rancid. It is an emollient that leaves a soft, sealed feel.
- Glyceryl Stearate emulsifier
- Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- Cetearyl Olivate emulsifier
- Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.
26 more explained
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- Sorbitan Olivate emulsifier
- Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
- Tromethamine pH adjuster
- Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
- Hippophae Rhamnoides Fruit Extract plant 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.
- Coptis Japonica Root Extract plant extract
- Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
- Sodium Polyacryloyldimethyl Taurate thickener
- Sodium Polyacryloyldimethyl Taurate is a polymer thickener that holds a gel stable even with a lot of salt or acid in the formula.
- Hydrogenated Polydecene emollient
- Hydrogenated Polydecene is a synthetic hydrocarbon emollient used in place of mineral oil. It is stable, has no scent, and gives a cushioned slip without oxidising.
- Ethylhexylglycerin preservative booster
- Ethylhexylglycerin softens skin and boosts a preservative system, which is why it is nearly always sitting beside phenoxyethanol or 1,2-hexanediol. It also cuts down the odour bacteria produce, so it turns up in deodorising products.
- Disodium EDTA chelator
- EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
- Biosaccharide Gum-1 polysaccharide
- 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.
- Melia Azadirachta Flower Extract plant extract
- Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
- Ocimum Sanctum Leaf Extract plant extract
- Ocimum Sanctum is holy basil, or tulsi. Its leaf extract carries plant antioxidants and is used in formulas built for the look of stressed, reactive skin.
- Hippophae Rhamnoides Oil emollient
- Sea buckthorn oil, deep orange from its carotenoid content, which is often why a formula carrying it has a colour nobody added. It is high in the unusual fatty acid palmitoleic acid.
- 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.
- Theobroma Cacao (Cocoa) Seed Extract plant extract
- Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
- Trideceth-10 emulsifier
- An ethoxylated fatty alcohol used as an emulsifier and solubiliser. It dissolves small amounts of oil or fragrance into a watery formula without clouding it.
- Ammonium Polyacryloyldimethyl Taurate thickener
- Ammonium Polyacryloyldimethyl Taurate is a polymer thickener that gels instantly and gives a light, silky body.
- Hyaluronic Acid humectant
- Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
- Hydrolyzed Hyaluronic Acid humectant
- Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
- 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.
- Curcuma Longa (Turmeric) Root Extract plant extract
- Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
- Corallina Officinalis Extract plant extract
- Corallina Officinalis is coral seaweed, which holds calcium and magnesium in its structure. Its extract is used as a mineral-rich conditioning ingredient.
- 3-O-Ethyl Ascorbic Acid antioxidant
- 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.
- Dextrin thickener
- Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Ascorbic Acid antioxidant
- 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.

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.
