How it works
The Green Tangerine Vita-C E TXA Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Tranexamic Acid, named fifth on its own ingredient list. The same list carries Niacinamide, Adenosine and Nicotinamide Mononucleotide, so the active is not the only thing on it worth naming. How much of the Tranexamic 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 goodal sells in Korea, Tranexamic Acid and all.

- Adenosine Triphosphate and Gluconolactone further down the same list
- Nonapeptide-1 and Cyanocobalamin further down the same list
- Tranexamic Acid named fifth on the manufacturer list printed on this page
- Sourced for the Korean market, not a US-shelf reformulation of this serum
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 Tranexamic Acid and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Tranexamic 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 Tranexamic Acid?
Niacinamide, Adenosine and Nicotinamide Mononucleotide. The order they are printed in on this serum's panel is the order on the box, so you can see where Tranexamic Acid sits relative to them. Further down the same panel: Nicotinamide Adenine Dinucleotide, Adenosine Triphosphate and Gluconolactone.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

Ingredient list read from inkeedecoder.com on 10 September 2026.
53 of 53 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.
- Citrus Tangerina (Tangerine) Extract plant extract
- Tangerine extract, carrying citrus flavonoids, sugars and a little citric acid. It is used as a conditioning antioxidant botanical.
- 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.
- 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.
- Tranexamic Acid active
- Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired.
- 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.
- 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.
- 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.
- 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.
- Tocopheryl Acetate antioxidant
- Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula.
- Pentylene Glycol humectant
- Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
- 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.
41 more explained
- Diethoxyethyl Succinate solvent
- Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
- Chondrus Crispus Extract plant extract
- Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
- 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.
- Saccharum Officinarum (Sugarcane) Extract plant extract
- Sugarcane Extract carries natural glycolic acid and sugars. In cosmetics it is used as a humectant; the acid content is far too low to work as an exfoliant.
- 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.
- 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.
- Ammonium Acryloyldimethyltaurate/VP Copolymer thickener
- This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
- 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.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- 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.
- Helianthus Annuus (Sunflower) Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- Adenosine active
- 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.
- Ascorbyl Glucoside antioxidant
- Ascorbyl Glucoside is vitamin C bound to glucose, which keeps it stable until enzymes in skin release it. It is a mild, slow-release route to a vitamin C formula.
- 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.
- 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.
- Ferulic Acid antioxidant
- Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often.
- 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.
- Beta-Glucan polysaccharide
- Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
- Citrus Aurantium Bergamia (Bergamot) Fruit Oil fragrance component
- Bergamot Fruit Oil is a citrus essential oil and the top note of eau de cologne. It scents a formula; citrus oils are the aromatic class most likely to bother reactive skin.
- 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.
- Alkanna Tinctoria Root Extract plant extract
- Alkanet root extract. The root is deep red-purple, so it colours a formula naturally, and it is used as a conditioning extract.
- Sodium Ascorbyl Phosphate antioxidant
- Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging.
- Citrus Limon (Lemon) Peel Oil fragrance
- Cold-pressed lemon peel oil. Citrus peel oils carry limonene and can make skin more sensitive to sunlight, which is why leave-on formulas use them sparingly.
- Camellia Sinensis Seed Oil emollient
- Oil pressed from tea seeds. It is high in oleic acid, carries some of the antioxidants of the tea plant, and is lighter in feel than most oleic oils.
- Lavandula Angustifolia (Lavender) Oil fragrance component
- Lavender Oil is an essential oil carrying linalool and linalyl acetate. It scents a formula, and linalool is one of the fragrance components EU labelling requires to be named separately.
- Citrus Aurantium Dulcis (Orange) Peel Oil fragrance component
- Sweet Orange Peel Oil is a citrus essential oil carrying limonene. It scents a formula, and limonene is one of the components EU labelling names separately.
- Eucalyptus Globulus Leaf Extract plant extract
- Eucalyptus leaf extract, the water-based extract rather than the essential oil. It carries tannins and flavonoids with only a trace of the aroma.
- Cananga Odorata Flower Oil fragrance
- Ylang ylang oil, a heavy sweet floral essential oil. It is among the most commonly declared natural fragrance materials.
- 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.
- Gluconolactone exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- Yeast Ferment Extract ferment
- The extract of a yeast culture, carrying amino acids, sugars and B vitamins. It is used as a conditioning ferment.
- Candida Bombicola/Glucose/Methyl Rapeseedate Ferment ferment
- This ferment produces sophorolipids, sugar-based molecules that behave as very mild surfactants and emulsifiers. It is used to keep a formula blended without a harsh cleanser.
- Polyglyceryl-10 Oleate emulsifier
- Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
- Nicotinamide Mononucleotide active
- Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself.
- Nicotinamide Adenine Dinucleotide active
- Nicotinamide Adenine Dinucleotide, usually written NAD, is a coenzyme every living cell carries, built from vitamin B3. In a formula it is used as a conditioning active at very low levels.
- Adenosine Triphosphate active
- Adenosine Triphosphate is the molecule cells move energy around with. In a formula it is a conditioning nucleotide, related to the adenosine declared beside it.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- Phosphatidylcholine emulsifier
- Phosphatidylcholine is the main phospholipid in lecithin and in cell membranes. It emulsifies and forms the liposome walls a formula uses to carry an active.
- 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.
- Calcium Pantothenate vitamin
- Calcium Pantothenate is the calcium salt of pantothenic acid, vitamin B5. It is the salt form of the same vitamin panthenol converts to, and it hydrates and conditions.
- Nonapeptide-1 peptide
- Nonapeptide-1 is a nine-amino-acid peptide used for the look of uneven tone rather than for firmness, which makes it unusual among cosmetic peptides.

How to use
- Cleanse and tone, then apply this while the skin is still slightly damp so it spreads without dragging.
- Use one or two pumps for the whole face and press it in with flat palms rather than rubbing in circles.
- Wait until the surface feels tacky rather than wet, then put your moisturiser on top.
- Do not use it as your only layer on dry skin, since a light fluid left uncovered is the first thing to evaporate.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Tranexamic Acid on the list.
- Gluconolactone on this list makes this serum an exfoliating step, so do not stack it with another one on the same night.
