Key actives
3Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named third.
15Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named fifteenth on this serum's list, alongside Niacinamide.
18Adenosineactive
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 eighteenth on this serum's list, alongside Niacinamide.
28Allantoinactive
Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin. The panel names it twenty-eighth on this serum's list, beside Niacinamide.
49Copper Tripeptide-1peptide
Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines. It is named forty-ninth on this serum's list, alongside Niacinamide.

Centellian24 Boosting Shot Gel 150ml
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?
Dipotassium Glycyrrhizate, Adenosine and Allantoin. 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: Copper Tripeptide-1, Acetyl Hexapeptide-8 and Tocopherol.
Not on the ingredient list below: denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

50 of 50 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener
- This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
- 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.
- Birch Sap plant extract
- Birch juice is sap tapped from the white birch in spring. It is mostly water with sugars, minerals and amino acids, and Korean formulas use it in place of water as the base.
- 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.
38 more explained
- Polyglyceryl-10 Isostearate emulsifier
- A ten-unit polyglycerin ester, very water-loving, used as a mild emulsifier and solubiliser in place of a PEG.
- 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.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- Glycerin Acrylate/Acrylic Acid Copolymer film former
- This is a polymer that forms a moisture-holding film on the surface, usually supplied with glycerin and propylene glycol as a hydrating complex.
- Polyglyceryl-10 Oleate emulsifier
- Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
- 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.
- 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.
- 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.
- Ammonium Acryloyldimethyl Taurate/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.
- 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.
- Sodium Chloride thickener
- Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
- 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.
- Sodium Bicarbonate pH adjuster
- Baking soda. In a formula it raises pH, and in a fizzing product it is the half that meets an acid and releases carbon dioxide.
- Calcium Chloride mineral
- Calcium Chloride is a mineral salt used in traces to balance a formula and to firm up gels made with alginate or gellan gum.
- Potassium Chloride mineral
- Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.
- Allantoin active
- Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
- 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.
- 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.
- 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.
- Soluble Collagen protein
- Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.
- 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.
- 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.
- 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.
- Lavender Extract plant extract
- Lavender Flower Extract is the water-based extract rather than the essential oil, so it is much milder and less aromatic.
- Oregano Flower/Leaf/Stem Extract plant extract
- Oregano extract from the whole plant above ground, rich in carvacrol and thymol. It is used as a plant antioxidant.
- Rosemary Extract plant extract
- Rosemary extract with the plant part unstated. Rosemary carries rosmarinic and carnosic acid, and it is also used to keep the oils in a formula from going rancid.
- Thyme Extract plant extract
- Thyme leaf extract, carrying the phenols thymol and carvacrol along with rosmarinic acid. It is used as an antioxidant herbal extract.
- 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.
- Cetyl Alcohol fatty alcohol
- Cetyl Alcohol is a waxy fatty alcohol from coconut or palm, unrelated to drying ethanol. It thickens creams, stabilises the emulsion and leaves skin feeling softer.
- Potassium Sorbate preservative
- Potassium Sorbate is a preservative that holds off yeast and mould in acidic formulas. It is almost always used with sodium benzoate, because neither covers the whole range of microbes alone.
- Sodium Benzoate preservative
- Sodium Benzoate is a mild preservative that works only in acidic formulas. It is usually paired with potassium sorbate, and the pair is the standard choice where a brand wants no phenoxyethanol.
- Citric Acid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- 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.
- Caprylyl/Capryl Glucoside surfactant
- Caprylyl/Capryl Glucoside is a sugar-derived cleansing surfactant. It foams modestly and is mild enough for low-pH cleansers built for reactive skin.
- Hydrolyzed Collagen protein
- Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
- 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.
- Copper Tripeptide-1 peptide
- Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
- Acetyl Hexapeptide-8 peptide
- Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.

How it works
The Boosting Shot Gel is a 150ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named third on its own ingredient list. The same list carries Dipotassium Glycyrrhizate, Adenosine and Allantoin, 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. Centellian24 sells this Niacinamide serum in Korea, and this is that version.
How to use
- Use it after cleansing and before your serum, morning and evening.
- A layer pressed over damp skin; it is watery, so it goes on fast and settles in seconds.
- In hot weather it can be the only thing after cleansing, with sunscreen over it in the morning.
- Twice a day. Do not wait for it to dry before the next step; layer while the skin is still damp.
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.
