How it works
The Vitamin C Glow Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The antioxidant it is built around is Ascorbic Acid, named fourth on its own ingredient list. The same list carries Niacinamide, Cyanocobalamin and Tocopherol, so the antioxidant is not the only thing on it worth naming. How much of the Ascorbic Acid 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 Hanskin sells in Korea, Ascorbic Acid and all.
Key benefits
- Ascorbic Acid, the antioxidant this serum is built around
- Niacinamide on the same list, an active
- Cyanocobalamin on the same list, a vitamin
- Tocopherol on the same list, an antioxidant
- Ascorbic Acid named fourth on the manufacturer list printed on this page
- Original Korean Formula, the serum sold on Korean shelves
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 Ascorbic Acid and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Ascorbic Acid 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 Ascorbic Acid?
Niacinamide, Cyanocobalamin and Tocopherol. The order they are printed in on this serum's panel is the order on the box, so you can see where Ascorbic Acid sits relative to them. Ascorbic Acid itself is named fourth on it.

Ingredient list read from inkeedecoder.com on 10 September 2026.
18 of 18 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.
- Ethoxydiglycol solvent
- Ethoxydiglycol is a solvent that keeps stubborn actives in solution, most often vitamin C or an acid, and helps them spread evenly instead of settling out.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- 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.
- 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.
- 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.
- Choleth-24 emulsifier
- Choleth-24 is a cholesterol-derived solubiliser. It keeps oils and oil-soluble actives dissolved in a clear formula.
- 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.
- Polyacrylate Crosspolymer-6 thickener
- Polyacrylate Crosspolymer-6 is a thickener chosen for a notably fresh, bouncy gel feel that breaks down to water on the skin.
- 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.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- Polyglyceryl-10 Oleate emulsifier
- Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
6 more explained
- 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.
- Citrus Grandis (Grapefruit) Peel Oil fragrance component
- Grapefruit Peel Oil is a citrus essential oil rich in limonene. It scents a formula and belongs to the aromatic class reactive skin often avoids.
- Hydrogenated Lecithin emulsifier
- Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
- 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.
- Sodium Phytate chelator
- Sodium Phytate is a rice-derived chelator used in place of EDTA. It ties up trace metals so the formula stays stable and its colour and scent hold.
- Cyanocobalamin vitamin
- Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin.
