Key actives
5Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named fifth.
13Adenosineactive
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. It is named thirteenth on this serum's list, alongside Niacinamide.
14Cyanocobalaminvitamin
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. It is named fourteenth on this serum's list, alongside Niacinamide.
16Astaxanthinantioxidant
Astaxanthin is a deep red antioxidant from microalgae, the pigment that makes salmon pink. It is oil soluble, colours a formula noticeably, and is used as an antioxidant. It is named sixteenth on this serum's list, alongside Niacinamide.
26Tranexamic Acidactive
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. The panel names it twenty-sixth on this serum's list, beside Niacinamide.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
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.
Does this serum contain fragrance?
Yes. The ingredient list names Fragrance. It sits on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this serum is not the one.
What else is on the list besides Niacinamide?
Adenosine, Tranexamic Acid and Cyanocobalamin. 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: Astaxanthin, Tocopherol and Glutathione.
Not on the ingredient list below: denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

Ingredient list read from incidecoder.com on 10 September 2026.
53 of 54 explained
- Aqua (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.
- 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.
- 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.
- PEG-240/Hdi Copolymer Bis-Decyltetradeceth-20 Ether thickener
- A polyethylene glycol copolymer used to thicken water based formulas that contain surfactants. It builds body without the tack a gum gives.
- 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.
- 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.
- Gellan Gum thickener
- Gellan Gum is a fermentation-derived polysaccharide that sets a clear, brittle gel at very low levels. It is used to suspend particles without thickening the liquid much.
- C12-14 Alketh-12 emulsifier
- C12-14 Alketh-12 is a solubiliser used to keep oils and fragrance dissolved in a water-based formula.
- Moringa Oleifera Seed Extract plant extract
- Moringa seed extract. The seed is best known for its oil and for the cationic peptides used to clarify water, and in a formula the extract is a conditioning botanical.
- 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.
41 more explained
- 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.
- 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.
- Sodium Polyacrylate thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
- Astaxanthin (200 Ppm) antioxidant
- Astaxanthin is a deep red antioxidant from microalgae, the pigment that makes salmon pink. It is oil soluble, colours a formula noticeably, and is used as an antioxidant.
- Fragrance fragrance
- Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
- 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.
- Theobroma Cacao (Cocoa) 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.
- Polyglutamic Acid humectant
- Polyglutamic Acid comes from fermented soy and holds several times more water than hyaluronic acid for its weight. It forms a light film on the surface, so it is often layered with hyaluronic rather than replacing it.
- 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.
- Potassium Laurate surfactant
- Potassium Laurate is the potassium soap of lauric acid, made by neutralising the fatty acid with potassium hydroxide. It is a foaming cleansing surfactant used in soap based cleansers.
- Glutathione antioxidant
- Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
- 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.
- Thioctic Acid antioxidant
- Thioctic Acid is alpha lipoic acid, an antioxidant that dissolves in both water and oil, which is unusual. It is yellow and carries a faint sulfur smell.
- 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.
- 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.
- 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.
- Glycine amino acid
- Glycine is the smallest amino acid and one of the free amino acids skin holds to keep water in the outer layer. In a formula it is a humectant and a mild buffer.
- Glutamic Acid amino acid
- Glutamic Acid is an amino acid used as a humectant and a mild pH adjuster. It is one of the components of skin's natural moisturising factor.
- Leucine amino acid
- Leucine is an essential amino acid used as a humectant, part of the amino acid block many Korean essences carry.
- Methionine amino acid
- Methionine is a sulphur-bearing essential amino acid used as a humectant and mild antioxidant.
- Valine amino acid
- Valine is an essential amino acid used as a humectant alongside the rest of an amino acid block.
- Serine amino acid
- Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
- Aspartic Acid amino acid
- Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
- Alanine amino acid
- Alanine is a free amino acid skin uses as part of its own moisture-holding system. In a formula it hydrates and conditions.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Isoleucine amino acid
- Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
- Phenylalanine amino acid
- Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
- Proline amino acid
- Proline is an amino acid abundant in collagen and one of skin's own humectants. Added to a formula it holds water in the outer layer.
- Histidine amino acid
- Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
- Taurine amino acid
- Taurine is an amino acid that occurs in high concentration inside the body cells, where it helps regulate water balance. In a formula it is a humectant and conditioning agent.
- Ornithine amino acid
- Ornithine is an amino acid the body makes on the way to urea. In a formula it is one of the amino acids used as a humectant and a component of the natural moisturising factor blend.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- Glucose humectant
- Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
- 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.
- Chondrus Crispus (Irish Moss) 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.
- Hydroxypropyltrimonium Hyaluronate humectant
- Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
- 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 Acetylated Hyaluronate humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
- 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.
- Sodium Hyaluronate Crosspolymer humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
- Potassium Hyaluronate humectant
- Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.

How it works
The TX Astaxanthin Triple Jelly Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named fifth on its own ingredient list. The same list carries Adenosine, Tranexamic Acid and Cyanocobalamin, 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. Dr. Melaxin sells this Niacinamide serum in Korea, and this is that version.
How to use
- Apply after the toner while the skin is still damp so a small dose spreads across the face.
- Work it over the whole face rather than only the darker patches, since even tone needs full coverage.
- Follow with a cream to hold it in place, and with sunscreen as the final morning step.
- Do not skip the sunscreen, since tone work without that last layer is undone faster than it is built.
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.
- This list names Fragrance, so skip it if fragrance components are something you avoid.
