Key actives
2Niacinamide
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.
4Glutathione
Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
5Mentha Piperita (Peppermint) Leaf Extract
Peppermint leaf extract, the water-based extract rather than the essential oil, so it carries far less menthol. It is used as a refreshing herbal extract.
6Primula Veris Extract
Cowslip extract, carrying saponins and flavonoids. It is used as a conditioning plant extract.

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.

42 of 48 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.
- 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.
- Helianthus Annuus (Sunflower) Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- Glutathione antioxidant
- Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
- Mentha Piperita (Peppermint) Leaf Extract plant extract
- Peppermint leaf extract, the water-based extract rather than the essential oil, so it carries far less menthol. It is used as a refreshing herbal extract.
- Primula Veris Extract plant extract
- Cowslip extract, carrying saponins and flavonoids. It is used as a conditioning plant extract.
- Achillea Millefolium Extract plant extract
- Yarrow extract. The plant carries flavonoids, tannins and azulene compounds, so the extract has an astringent character and is used as a conditioning botanical.
- Melissa Officinalis Leaf Extract plant extract
- Lemon balm extract, a mint-family herb rich in rosmarinic acid. It is used as an antioxidant conditioning extract with a light lemon scent.
- Morus Alba Bark Extract plant extract
- White mulberry bark extract, one of the classic East Asian plant ingredients used for the look of uneven tone. It carries mulberroside and flavonoids.
- Hamamelis Virginiana (Witch Hazel) Leaf Extract plant extract
- Witch hazel leaf extract, taken from the leaf rather than the bark. Like the bark it carries tannins and gives an astringent feel.
- 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.
- 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.
30 more explained
- Tocopheryl Acetate antioxidant
- Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula.
- Sodium Ascorbyl Phosphate antioxidant
- Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging.
- Pyridoxine vitamin
- Pyridoxine is vitamin B6. In a formula it is a conditioning vitamin, most often in B-complex blends and scalp products.
- Folic Acid vitamin
- Folic Acid is vitamin B9. It is used in a formula as a conditioning vitamin, usually as part of a B-complex blend.
- Thiamine HCl vitamin
- Thiamine is vitamin B1, supplied as its hydrochloride salt so it dissolves in water. It is a conditioning vitamin and usually appears as part of a B-complex.
- Cyanocobalamin vitamin
- Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- Retinyl Palmitate active
- Retinyl Palmitate is retinol bound to a fatty acid. It is the mildest common retinoid because skin has to make three conversions before it becomes active, which also makes it the least likely to cause flaking.
- 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.
- 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.
- Oligopeptide-29 peptide
- A short chain of amino acids used as a conditioning peptide. Oligopeptide numbers are registry entries, not strengths.
- Oligopeptide-32 peptide
- A short amino acid chain used as a conditioning peptide, usually one of several oligopeptides declared together.
- Palmitoyl Pentapeptide-4 peptide
- Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
- 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.
- Polyacrylamide film former
- A polymer used to thicken and to hold an emulsion together. It leaves a light film that helps a formula stay put.
- 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.
- 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.
- Pulsatilla Koreana Extract plant extract
- Korean pasque flower extract, a native anemone relative. It is used as a conditioning plant extract, usually beside other Korean herbal extracts.
- Zanthoxylum Piperitum Fruit Extract plant extract
- Zanthoxylum Piperitum is Korean pepper. Its fruit extract is used as a conditioning plant extract and is often paired with pulsatilla and usnea in Korean formulas.
- Usnea Barbata (Lichen) Extract plant extract
- Beard lichen extract, carrying usnic acid. It resists microbes, so formulas use it both as a plant extract and as part of a preservative system.
- C13-14 Isoparaffin emollient
- A light branched hydrocarbon, usually part of the thickener system in a lotion. It gives a smooth, quick-spreading feel.
- 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.
- 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.
- Triethanolamine pH adjuster
- Triethanolamine is an alkaline base used to neutralise acidic gelling agents such as carbomer. Once neutralised the gel thickens, which is what holds a clear gel together.
- 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.
- Laureth-7 emulsifier
- Laureth-7 is a mild emulsifier and wetting agent. It helps oils and water mix and improves how evenly a formula spreads.
- 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.
- 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.
- 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.
- Polyglyceryl-10 Stearate emulsifier
- Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.

How it works
Glutathione leads the ingredient panel on this ampoule. Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it. On this panel it sits alongside Niacinamide, Mentha Piperita (Peppermint) Leaf Extract and Primula Veris Extract. 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.
