What is Radian-C Vitamin Spot Ampoule 10ml?

It is Laneige's ampoule. We stock Laneige's Korean-market formula, the version sold on shelves in Korea rather than a US-shelf reformulation.

How do I use Radian-C Vitamin Spot Ampoule 10ml?

Dispense a few drops of Radian-C Vitamin Spot Ampoule 10ml onto cleansed skin, press it in with your palms, then follow with moisturizer. Used consistently after toner and before moisturizer, as the routine's concentrated step, give it a few weeks in that slot before judging whether it is working for you.

Who is Radian-C Vitamin Spot Ampoule 10ml suited for?

It suits normal, dry, combination, aimed at dullness and uneven tone. Patch test on a small area first if you are new to this formula or to the brand. Give the formula a few uses in that slot in your routine before deciding whether it fits your needs.

Is Radian-C Vitamin Spot Ampoule 10ml the authentic Korean formula?

Yes. We stock Laneige's Korean-market formula rather than a version reformulated for US shelves. The unit sold is the one listed on Korean shelves, with the Korean barcode and batch code intact on the box.

How should I store Radian-C Vitamin Spot Ampoule 10ml?

Keep Radian-C Vitamin Spot Ampoule 10ml away from direct sunlight and heat, and close the cap fully between uses so the formula stays stable for its full shelf life. A cool, dry spot out of a steamy bathroom is a better home for it than a windowsill or a shower shelf.

How it works

Radian-C Vitamin Spot Ampoule 10ml is Laneige's ampoule. Like most entries in this format, its job in a routine comes from texture and placement rather than one named active carrying the result on its own. Used after toner and before moisturizer, as the routine's concentrated step, it is built to address dullness and uneven tone. We stock Laneige's Korean-market formula, the same version sold on shelves in Seoul rather than a formula built for US retail, with the Korean barcode and batch code intact on the box.

Built as an ampoule, where texture and placement in a routine carry the result.

Aimed at dullness and uneven tone.

Inside the formula

Ingredients declared

#18

Fragrance on the list

1 of 2

34 of 35 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.
Ascorbic Acid antioxidant: Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.
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.
Dimethicone silicone: Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
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.
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.
Ethyl Ascorbyl Ether vitamin: A vitamin C derivative with an ethyl group on the third position, the same molecule usually written 3-O-Ethyl Ascorbic Acid. The ether makes it far more stable in water than pure ascorbic acid.
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.
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.
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.
Acetyl Glucosamine active: Acetyl Glucosamine is the sugar unit hyaluronic acid is built from. It is used as a humectant and, at higher levels, for the look of uneven tone, often paired with niacinamide.
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.

22 more explained

Caffeine active: Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the 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.
Sodium Sulfite antioxidant: A reducing agent used to stop vitamin C and other easily oxidised ingredients from browning in the bottle.
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.
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.
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.
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.
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.
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.
Citral fragrance component: Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.
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.
Arginine amino acid: Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
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.
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.
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.
Tranexamic Acid active: Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired.
Glycyrrhiza Glabra (licorice) Root Extract plant extract: Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
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.
Methyl Trimethicone silicone: Methyl Trimethicone is a light, volatile silicone chosen for a notably dry finish. It thins a formula and disperses powders evenly.
Carthamus Tinctorius (safflower) Seed Oil emollient: Safflower seed oil, among the highest-linoleic plant oils. High-linoleic oils feel lighter and absorb faster than high-oleic ones.
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.
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.
