How it works
The Hyaluronic Tox Boosting Ampoule is a 30ml ampoule, used after toner and before moisturizer, morning and evening. The humectant it is built around is Sodium Hyaluronate, named seventeenth on its own ingredient list. The same list carries Niacinamide, Adenosine and Lactobacillus Extracellular Vesicles, so the humectant is not the only thing on it worth naming. How much of the Sodium Hyaluronate stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule Centellian24 sells in Korea, Sodium Hyaluronate and all.

Centellian24 Hyaluronic Tox Boosting Ampoule 30ml
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule 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 Sodium Hyaluronate and not three changes at once.
Is this the Korean-market ampoule or a US version?
The Korean-market one, Sodium Hyaluronate and all. We match this ampoule 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 Sodium Hyaluronate?
Niacinamide, Adenosine and Lactobacillus Extracellular Vesicles. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Sodium Hyaluronate sits relative to them. Further down the same panel: BHT, Tocopherol and Ceramide NP.

Ingredient list read from centellian24.com on 18 August 2026.
43 of 46 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.
- ISOPENTYLDIOL solvent
- Isopentyldiol is a glycol used as a light solvent and humectant. It thins a formula, keeps extracts dissolved and leaves a dry finish.
- 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.
- 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.
- BIS-PEG-18 METHYL ETHER DIMETHYL SILANE silicone
- A water-soluble silicone used for a light, silky slip without an oily film. It also helps other ingredients spread evenly.
- 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.
- 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.
- 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.
- METHYLPROPANEDIOL humectant
- Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
- 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.
- HYDROXYACETOPHENONE preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
31 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.
- 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.
- 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.
- 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.
- 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.
- DIMETHYLSILANOL HYALURONATE humectant
- Dimethylsilanol Hyaluronate is hyaluronic acid joined to a silicon-based group. It hydrates and leaves a smoother, silkier finish than hyaluronic acid alone.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- FICUS CARICA (FIG) FRUIT EXTRACT plant extract
- Fig Fruit Extract carries fruit sugars, mild acids and a protein-digesting enzyme. It is used as a hydrating extract with a light smoothing effect.
- CENTELLA ASIATICA EXTRACT plant extract
- Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
- MANNITOL humectant
- Mannitol is a sugar alcohol used as a humectant and antioxidant. It hydrates and helps stabilise the rest of the formula against oxidation.
- BHT antioxidant
- BHT is a synthetic antioxidant used in traces to stop the oils in a formula going rancid. It protects the product, not the skin.
- LACTOBACILLUS EXTRACELLULAR VESICLES ferment
- Lactobacillus Extracellular Vesicles are the tiny membrane-bound packets bacteria release. They are a recent Korean formulation ingredient used as a conditioning ferment component.
- CERAMIDE NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
- 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.
- DIOSCOREA JAPONICA ROOT EXTRACT plant extract
- Dioscorea Japonica is Japanese wild yam, whose root is naturally slippery with mucilage. Its extract hydrates and leaves a cushioned feel.
- 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.
- HYDROLYZED CORN STARCH absorbent
- Hydrolyzed Corn Starch is starch broken into smaller fragments. It gives a silky, powdery slip and absorbs a little oil.
- SODIUM PALMITOYL SARCOSINATE surfactant
- Sodium Palmitoyl Sarcosinate is an amino-acid-derived cleanser built on sarcosine. It foams well at skin-friendly pH, which is why Korean low-pH cleansers use it.
- 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.
- PVM/MA COPOLYMER film former
- PVM/MA Copolymer is a film-forming polymer used to hold a formula in place and, in a mask, to give the peel-off film its strength.
- 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.
- SOLUBLE PROTEOGLYCAN protein
- A proteoglycan is a protein with sugar chains attached, the same architecture as the water-holding molecules in cartilage and skin. Made soluble, it is used as a humectant and conditioning protein.
- SUCROSE humectant
- Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.

How to use
- Use it after toner and before moisturizer, morning and evening, on damp skin.
- A thin layer pressed in with flat palms while the toner underneath is still wet.
- Follow with a cream, because hyaluronates on a bare surface dry out rather than staying put.
- Twice a day. Do not use it on a dry face with nothing over the top.
Worth knowing
- Patch test this ampoule on a small area and wait a day before using it more widely, especially with Sodium Hyaluronate on the list.
- Introduce this ampoule on its own for the first week, so anything your skin does is traceable to the Sodium Hyaluronate rather than to three changes at once.
