Key benefits
- Three forms of retinol on one panel, not a single token inclusion
- Niacinamide on the same panel, the formula's active
- Hippophae Rhamnoides Fruit Extract on the same panel, the formula's plant extract
- 30 ml to a unit
- Korean-market formula, with its Korean barcode and batch code intact on the box
Key actives
7Niacinamide
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.
21Hippophae Rhamnoides Fruit Extract
Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract.
23Tocopherol
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.
26Retinal
Retinal is retinaldehyde, a vitamin A derivative one chemical step closer to retinoic acid than retinol is. It is yellow-orange and unstable in light, so products carrying it are usually opaque.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
How do I use this ampoule?
Apply a few drops to clean skin after toner, morning or night as directed on the pack, and follow with moisturizer to seal it in. Ampoules are typically used as a concentrated course rather than an everyday staple.
Is an ampoule the same as a serum?
It sits in the same step but at a higher concentration, so many people use it as a shorter, more intensive course rather than every single day.

Ingredient list read from incidecoder.com on 30 August 2026.
59 of 67 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.
- 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.
- 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.
- 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.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- 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.
- 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.
- Cetyl Palmitate emollient
- Cetyl Palmitate is a wax ester, the same kind of molecule that makes up much of spermaceti and jojoba. It thickens the oil phase and leaves a smooth, non-greasy film.
- 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.
- 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.
- 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.
47 more explained
- 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 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Hippophae Rhamnoides Fruit Extract plant extract
- Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract.
- 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.
- 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.
- 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.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- Retinal active
- Retinal is retinaldehyde, a vitamin A derivative one chemical step closer to retinoic acid than retinol is. It is yellow-orange and unstable in light, so products carrying it are usually opaque.
- Polyglyceryl-10 Oleate emulsifier
- Polyglyceryl-10 Oleate is a mild sugar-derived emulsifier and solubiliser used where a formula must stay clear.
- 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.
- Inulin Lauryl Carbamate emulsifier
- A chicory-sugar polymer with a fatty chain attached. It stabilises an emulsion by forming a film at the oil and water boundary rather than acting as a classic surfactant.
- 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.
- 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.
- 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.
- 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.
- Brassica Campestris (Rapeseed) Sterols emollient
- Phytosterols are plant sterols, structurally close to the cholesterol in skin's own lipid layer. They soften skin and help the oil phase of a formula hold together.
- 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.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- 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.
- Phytosteryl/Behenyl/Octyldodecyl Lauroyl Glutamate barrier lipid
- An amino-acid-based lipid built on plant sterols. It structures the oil phase of a cream and echoes the lipid mix that already sits between skin cells.
- 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.
- Erythritol humectant
- Erythritol is a sugar alcohol humectant with a faint cooling feel as it dissolves. It hydrates and helps a formula spread without tack.
- 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.
- Camellia Japonica Flower Extract plant extract
- Camellia Japonica Flower Extract comes from the flower of the Korean camellia. It is used as a conditioning, hydrating extract.
- Nicotinamide Adenine Dinucleotide active
- Nicotinamide Adenine Dinucleotide, usually written NAD, is a coenzyme every living cell carries, built from vitamin B3. In a formula it is used as a conditioning active at very low levels.
- Nicotinamide Mononucleotide active
- Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself.
- Pentaerythrityl Tetra-Di-T-Butyl Hydroxyhydrocinnamate antioxidant
- This is a stabiliser that keeps the oils and fragrance in a formula from oxidising. Its job is the shelf life of the product rather than any effect on skin.
- Aluminum/Magnesium Hydroxide Stearate dispersant
- A mineral soap used to suspend powders and thicken an oil phase, which is what stops pigment settling to the bottom of a bottle.
- 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.
- Potassium Cetyl Phosphate emulsifier
- Potassium Cetyl Phosphate is an emulsifier prized for keeping powdered ingredients evenly suspended, which is why tinted and mineral-powder textures use it.
- PPG-13-Decyltetradeceth-24 emulsifier
- PPG-13-Decyltetradeceth-24 is a solubiliser used to hold oils and fragrance in a clear water-based formula.
- Dimethyl Isosorbide solvent
- Dimethyl Isosorbide is a solvent used to dissolve actives that water and oil both reject, and to carry them evenly through the outer layer of skin. It appears in vitamin C and retinoid formulas for exactly that reason.
- Tris(Tetramethylhydroxypiperidinol) Citrate antioxidant
- A hindered-amine antioxidant used to keep a formula from breaking down in light and air. It works on the product rather than on skin.
- Sodium Surfactin surfactant
- A biosurfactant produced by Bacillus fermentation. It lowers surface tension at very low concentrations, so a formula needs very little of it.
- Rosmarinus Officinalis (Rosemary) Leaf Extract plant extract
- Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
- Hydroxypinacolone Retinoate active
- Hydroxypinacolone Retinoate is a retinoid ester that binds skin's retinoid receptors directly, with no conversion step. Brands use it where they want retinoid-style results with less of the flaking retinol brings.
- Bakuchiol active
- Bakuchiol is a compound from the babchi seed, used as a plant-derived alternative to retinol. It is oil soluble, stable in daylight and does not carry retinol's acclimatisation period, which is why sensitive-skin formulas choose it.
- Glucosylrutin antioxidant
- Glucosylrutin is the flavonoid rutin with a sugar attached, which makes it dissolve in water. It is used as a plant antioxidant.
- Benzotriazolyl Dodecyl P-Cresol antioxidant
- A light stabiliser. Its job is to keep the formula itself from degrading in light, so it is a product-stability ingredient rather than one aimed at skin.
- 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.
- Benzyl Salicylate fragrance component
- Benzyl Salicylate is a faint floral aromatic that also holds a fragrance on skin longer. It is one of the 26 fragrance components EU labelling requires to be named.
- 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
The panel on this formula names three forms of retinol rather than one: Retinal, Retinyl Acetate, Retinyl Retinoate. Retinal is retinaldehyde, a vitamin A derivative one chemical step closer to retinoic acid than retinol is. It is yellow-orange and unstable in light, so products carrying it are usually opaque. On this panel it sits alongside Niacinamide, Hippophae Rhamnoides Fruit Extract and Tocopherol. 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.
How to use
- Apply a few drops to clean skin after toner, morning or night as directed on the pack, and follow with moisturizer to seal it in. Ampoules are typically used as a concentrated course rather than an everyday staple.
Worth knowing
- Introduce gradually and patch test first, since ampoules are formulated at a higher concentration than a standard serum.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Vitamin A has a molecular structure that's tiny enough to get into the lower layers of your skin, where it finds and boosts collagen and elastin, which is a protein that strengthens your skin's flexibility.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic 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.
