How it works
The Moisture Balancing Serum is a 50ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named eighth on its own ingredient list. The same list carries Adenosine, Lactobacillus Ferment and Ceramide NP, 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. Baegayul sells this Niacinamide serum in Korea, and this is that version.
Key benefits
- Niacinamide, the active this serum is built around
- Adenosine on the same list, an active
- Lactobacillus Ferment on the same list, a ferment
- Ceramide NP on the same list, a barrier lipid
- Centella Asiatica Extract and Ficus Carica (Fig) Fruit Extract further down the same list
- Curcuma Longa (Turmeric) Root Extract and Dioscorea Japonica Root Extract further down the same list
Key actives
8Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this serum's own ingredient list it is named eighth.
23Lactobacillus Fermentferment
Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin. It is named twenty-third on this serum's list, alongside Niacinamide.
31Adenosineactive
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. The panel names it thirty-first on this serum's list, beside Niacinamide.
35Ceramide NPbarrier 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. The panel names it thirty-fifth on this serum's list, beside Niacinamide.
36Biosaccharide Gum-1polysaccharide
Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel. The panel names it thirty-sixth on this serum's list, beside Niacinamide.
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.
What else is on the list besides Niacinamide?
Adenosine, Lactobacillus Ferment and Ceramide NP. 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: Biosaccharide Gum-1, Centella Asiatica Extract and Ficus Carica (Fig) Fruit Extract.

34 of 37 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.
- 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.
- 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.
- 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.
- Methyl Gluceth-20 humectant
- Methyl Gluceth-20 is a sugar-derived humectant. It holds water in the outer layer of skin and gives a smooth, cushioned slip that plain glycerin does not.
- 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.
- 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.
- 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.
- 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.
- Curcuma Longa (Turmeric) Root Extract plant extract
- Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
- 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.
22 more explained
- Coix Lacryma-Jobi MA-Yuen Seed Extract plant extract
- Adlay, or Job tears, a grain used in both Korean cooking and Korean herbal practice. The seed extract carries starch-derived sugars and amino acids.
- Sophora Flavescens Root Extract plant extract
- Kushen root extract, a bitter traditional herbal ingredient carrying alkaloids and flavonoids. Korean formulas use it in scalp and blemish-focused products.
- Rheum Palmatum Root/Stalk Extract plant extract
- Chinese rhubarb root and stalk extract, a long-standing East Asian herbal ingredient. It carries anthraquinones and tannins.
- Scutellaria Baicalensis Root Extract plant extract
- Scutellaria Baicalensis is Chinese skullcap. Its root extract carries baicalin, a well studied plant antioxidant, and it is used for the look of redness.
- Phellodendron Amurense Bark Extract plant extract
- Amur cork tree bark, another traditional berberine-bearing herbal ingredient. It is yellow and appears in blends aimed at the look of congested skin.
- 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.
- 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.
- Lactobacillus Ferment ferment
- Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.
- 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.
- 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.
- 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.
- Glycosyl Trehalose humectant
- A sugar humectant built on trehalose, the sugar that lets some plants survive drying out. It holds water at the surface with a light, non-sticky feel.
- Hydrogenated Starch Hydrolysate humectant
- A starch-derived sugar syrup used as a humectant. It holds water and adds a soft cushioned slip without the tack of glycerin.
- Raffinose sugar
- Raffinose is a three-unit plant sugar found in beans and beetroot. It holds water in the outer layer of skin and helps a formula stay comfortable as it dries down.
- 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.
- 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.
- Lecithin emulsifier
- Lecithin is a soy or sunflower-derived phospholipid, the same class of molecule cell membranes are built from. It emulsifies oil into water and is the basis of the liposomes formulators use to carry actives.
- Polyquaternium-51 film former
- Polyquaternium-51 is a polymer, sometimes sold as Lipidure, built on the same phosphorylcholine structure as a cell membrane. It holds water in a film on the surface and gives a distinctive soft, dry finish.
- 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.
- Biosaccharide Gum-1 polysaccharide
- Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel.
- 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.

How to use
- Use this serum AM and/or PM, as the serum step, after toner or essence and before moisturizer. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.
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.
- Introduce this serum on its own for the first week, so anything your skin does is traceable to the Niacinamide rather than to three changes at once.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
