Key actives
14Ceramide Np
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.
18Phospholipids
Phospholipids are the lipid class lecithin belongs to, with a water friendly head and two fatty tails. That shape is what lets them form liposomes and hold an emulsion together.
22Cholesterol
Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
25Phytosphingosine
Phytosphingosine is the backbone every ceramide is built on, and skin uses it in its own lipid layer. In a formula it works with ceramides and cholesterol and also keeps the product stable against microbes.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
Is the Brightening Ampoule 30ml sold here YUNJAC's Korean-market formula?
Yes. What ships is YUNJAC's release for the Korean market: the formula and packaging sold in Korea, with the Korean-market barcode and batch code intact on the box rather than swapped for an export or US-retail label.
Where does the Brightening Ampoule 30ml go in a routine?
It takes after toner and before moisturizer. As a serum, its place in the sequence follows from its format rather than any brand-specific instruction beyond that. A serum in this format is built to carry a concentrated dose of its named actives in a light enough base that it absorbs before the next step goes on, which is also why it belongs at that point in the sequence rather than earlier or later.
Who is the Brightening Ampoule 30ml best suited for?
Normal, Combination, Dry skin types get the most straightforward use from a serum in this format. Patch test first, as with any new product entering a routine, and give it a week or two before judging the fit.
What format is the Brightening Ampoule 30ml, and how does that change how it is used?
It is a serum, and the format sets the routine rules that come with it: Apply to clean, toned skin, pressing in gently before the next step. YUNJAC builds this one to match that format rather than departing from it.
How does buying the Brightening Ampoule 30ml here compare with a US retailer carrying the same name?
A US listing under the same product name can be a reformulated export version and rarely states which one it is selling. What we carry is the Korean-market YUNJAC release, identified by its intact Korean barcode and batch code on the box rather than a relabeled export carton, so the unit you get matches what is sold on shelf in Korea.

Ingredient list read from yunjac.com on 30 August 2026.
35 of 38 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.
- 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.
- Squalane emollient
- Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
- Simmondsia Chinensis (jojoba) Seed Oil emollient
- Jojoba Oil is a liquid wax rather than a true oil, and its structure is close to human sebum, which is why it absorbs so readily. It is an emollient that leaves a soft, non-greasy finish.
- 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.
- Polyglyceryl-10 Stearate emulsifier
- Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
- Dipentaerythrityl Hexahydroxystearate/Hexastearate/Hexarosinate emollient
- A thick rosin-bearing ester used in lip products for shine and staying power. It is what makes a gloss cling rather than slide off.
- 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.
- 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.
- Glyceryl Stearate emulsifier
- Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
- Behenyl Alcohol fatty alcohol
- Behenyl Alcohol is a long-chain fatty alcohol used to thicken and stabilise a cream. It gives a richer, more velvety body than cetyl alcohol.
23 more explained
- Shea Butter emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- 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.
- Triethylhexanoin emollient
- Triethylhexanoin is a light ester emollient that softens skin and disperses pigment. It absorbs cleanly and is often used to thin a heavy oil phase.
- 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.
- Phospholipids barrier lipid
- Phospholipids are the lipid class lecithin belongs to, with a water friendly head and two fatty tails. That shape is what lets them form liposomes and hold an emulsion together.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Hydrogenated Polydecene emollient
- Hydrogenated Polydecene is a synthetic hydrocarbon emollient used in place of mineral oil. It is stable, has no scent, and gives a cushioned slip without oxidising.
- Cetearyl Alcohol fatty alcohol
- Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- 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.
- Phytosphingosine barrier lipid
- Phytosphingosine is the backbone every ceramide is built on, and skin uses it in its own lipid layer. In a formula it works with ceramides and cholesterol and also keeps the product stable against microbes.
- 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.
- 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.
- Gardenia Florida Fruit Extract plant extract
- Gardenia Fruit Extract is the traditional East Asian yellow dye plant. In skincare it is used as an antioxidant extract, and it can tint a formula.
- Angelica Gigas Root Extract plant extract
- Korean angelica root, a staple of Korean herbal medicine. Its extract carries coumarins and is used as a conditioning herbal extract.
- 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.
- 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.
- 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.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.

How it works
Phospholipids is named on the ingredient panel on this ampoule. Phospholipids are the lipid class lecithin belongs to, with a water friendly head and two fatty tails. That shape is what lets them form liposomes and hold an emulsion together. On this panel it sits alongside Ceramide Np, Cholesterol and Phytosphingosine. 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.

What professionals say
What professionals say
What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.
Amy Kassouf, MDDermatologist, Cleveland Clinic Phytosphingosine is considered a precursor to ceramides, which are the dominant fat that fills in the cracks between skin cells.
