How it works
Medicube Deep Vita C Ampoule 2.0 is an ampoule built for the treatment step right after toner. Its ingredient list leads with Ascorbic Acid, Allantoin, and Sodium Hyaluronate, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Ascorbic Acid does the most work here as a brightening, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the treatment step right after toner, it is meant to be used AM/PM rather than swapped freely between steps. Because this is the Korean-market version of the Deep Vita C Ampoule 2.0 line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.
Key benefits
- Built around Ascorbic Acid, positioned for brightening.
- Built around Allantoin, positioned for comfort.
- Built around Sodium Hyaluronate, positioned for hydration.
- Formulated as an ampoule for the treatment step right after toner.
- The Korean-market Medicube formula for Deep Vita C Ampoule 2.0, matching what Medicube sells in Korea rather than a US-reformulated line.
Inside the formula
Inside the formula
Medicube Deep Vita C Ampoule 2.0
What does the Deep Vita C Ampoule 2.0 actually contain?
Its ingredient list is led by Ascorbic Acid, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.
How do I use the Deep Vita C Ampoule 2.0?
Use this ampoule as the treatment step right after toner. To apply, press a small amount into cleansed, toned skin and follow with moisturizer. Keep it to AM/PM unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.
Is the Deep Vita C Ampoule 2.0 the same formula sold in Korea, or a US version?
This Deep Vita C Ampoule 2.0 is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.
Can I use the Deep Vita C Ampoule 2.0 with other actives in my routine?
Yes, as long as it is used in its own step, the treatment step right after toner, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.
Who is the Deep Vita C Ampoule 2.0 suited for?
It suits most skin types looking for treatment step right after toner rather than a single acute problem. It comes in a 30g format. Anyone with a known sensitivity to a specific ingredient should check the full ingredient panel on this page before buying.

Ingredient list read from koreancare.net on 10 September 2026.
58 of 60 explained
- Water (Aqua) 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 (145,000ppm) 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.
- Dicaprylyl Carbonate emollient
- Dicaprylyl Carbonate is a light, fast-spreading emollient with a notably dry finish. It is chosen where a formula has to spread thin without leaving a heavy film.
- 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.
- 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.
- 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.
- Phenyl Trimethicone silicone
- Phenyl Trimethicone is a silicone with a higher refractive index than most, so it adds visible gloss as well as slip. It is common in glow and lip textures.
- Diisostearyl Malate emollient
- Diisostearyl Malate is a thick, glossy ester used to hold pigment in suspension and give a cushioned shine. It is the standard emollient in lip products.
- Hydrogenated Poly(C6-14 Olefin) emollient
- Hydrogenated Poly(C6-14 Olefin) is a synthetic hydrocarbon emollient. It gives a smooth, silicone-like glide and is completely stable, so it does not go rancid.
- 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-6 Stearate emulsifier
- Polyglyceryl-6 Stearate is a mild plant-derived emulsifier for oil-in-water creams.
- Polyglyceryl-3 Distearate emulsifier
- Polyglyceryl-3 Distearate is a plant-derived emulsifier used to hold oil and water together in creams and lotions.
46 more explained
- Sodium Hydroxide pH adjuster
- Sodium Hydroxide is a strong base used in traces to bring an acidic formula up to skin-friendly pH. None of it remains as itself once the formula is neutralised.
- 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.
- 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.
- Bisabolol active
- Bisabolol is the main active fraction of chamomile oil, usually supplied from candeia wood. It is used for the look of redness in formulas for reactive skin, and it helps other ingredients absorb.
- Sodium Stearoyl Glutamate emulsifier
- Sodium Stearoyl Glutamate is an amino-acid-derived emulsifier. It holds oil and water together and is mild enough for formulas built for reactive skin.
- Polyacrylate Crosspolymer-6 thickener
- Polyacrylate Crosspolymer-6 is a thickener chosen for a notably fresh, bouncy gel feel that breaks down to water on the skin.
- Pullulan film former
- Pullulan is a fermentation-derived polysaccharide that dries to a tight film, which is why it produces a temporary, visible tightening feel on the skin.
- Allantoin active
- Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
- 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.
- 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.
- 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.
- 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.
- Glyceryl Stearate Citrate emulsifier
- Glyceryl Stearate Citrate is a mild, citrate-modified emulsifier. It holds oil and water together and is chosen for formulas aimed at reactive skin.
- 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.
- Polyglyceryl-6 Behenate emulsifier
- A polyglycerin ester with a long fatty chain. It emulsifies and thickens at the same time, which is how a cream gets body without wax.
- Citrus Nobilis (Mandarin Orange) Peel Extract plant extract
- Mandarin peel extract, carrying citrus flavonoids and aromatic compounds. It is used as a conditioning antioxidant extract.
- Lycopodium Clavatum Extract plant extract
- Club moss extract, from a spore-bearing plant older than flowering plants. It is used as a conditioning extract.
- Equisetum Arvense Extract plant extract
- Horsetail extract, the plant richest in plant-bound silica. It is used as a conditioning, mineral-bearing extract.
- Beta-Glucan polysaccharide
- Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
- Cupressus Sempervirens Leaf/Stem Extract plant extract
- Italian cypress leaf and stem extract. The plant carries tannins and aromatic terpenes, so the extract has an astringent, resinous character.
- 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.
- Hedera Helix (Ivy) Leaf/Stem Extract plant extract
- Ivy Leaf and Stem Extract carries saponins, plant compounds that foam slightly in water. It is used in body and eye formulas for the look of puffiness.
- Citrus Aurantium Bergamia (Bergamot) Fruit Oil fragrance component
- Bergamot Fruit Oil is a citrus essential oil and the top note of eau de cologne. It scents a formula; citrus oils are the aromatic class most likely to bother reactive skin.
- Ribes Nigrum (Black Currant) Leaf Extract plant extract
- Blackcurrant leaf extract, carrying flavonoids and tannins. It is used as a conditioning antioxidant extract.
- Litsea Cubeba Fruit Oil fragrance
- May chang oil, a bright lemon-scented essential oil pressed from a small Asian tree. Its scent comes mostly from citral, the same aromatic that gives lemongrass its character.
- 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.
- 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.
- t-Butyl Alcohol solvent
- t-Butyl Alcohol is the bittering agent added to cosmetic ethanol so it cannot be drunk. It appears in tiny amounts alongside alcohol denat. and does no formulation work of its own.
- Sorbitol humectant
- Sorbitol is a sugar alcohol used as a humectant. It hydrates like glycerin with a smoother, less sticky finish, and it adds a little body to watery textures.
- 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.
- Hippophae Rhamnoides Water plant extract
- Hippophae Rhamnoides is sea buckthorn. Its water is used in place of plain water as a base and carries traces of the fruit's vitamins.
- 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.
- Sucrose Stearate emulsifier
- Sucrose Stearate is a sugar-based emulsifier chosen for a light finish in formulas built for reactive skin.
- Beta-Carotene antioxidant
- Beta-Carotene is an orange plant pigment and a vitamin A precursor. It is used as an antioxidant and it tints a formula, which is often why it is there.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- 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.
- Microcrystalline Cellulose absorbent
- Microcrystalline Cellulose is purified cellulose ground fine. It thickens, holds powders in suspension and gives a soft, matte feel.
- Ubiquinone antioxidant
- Ubiquinone is coenzyme Q10, an antioxidant every cell uses in its own energy production. In a formula it is oil soluble, faintly yellow, and used for the look of tired, dull skin.
- Cellulose Gum thickener
- Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
- Terminalia Ferdinandiana Fruit Extract plant extract
- Kakadu plum fruit extract, the highest natural source of vitamin C known. It is used as a plant antioxidant.
- Myrciaria Dubia Fruit Extract plant extract
- Camu camu fruit extract, an Amazonian berry with one of the highest vitamin C contents of any fruit. It is used as a plant antioxidant.
- Saccharide Hydrolysate humectant
- Saccharide Hydrolysate is a mixture of plant sugars broken down for use as a humectant. It holds water in the outer layer.
- Hesperidin antioxidant
- Hesperidin is the main flavonoid of citrus peel. It is used as a plant antioxidant and for the look of surface vessels.
- Fructooligosaccharides humectant
- Fructooligosaccharides are short fructose chains used as humectants and as food for the skin's own resident microbes.
- Ergothioneine antioxidant
- Ergothioneine is a sulphur-bearing amino acid mushrooms make. It is a strong antioxidant and is stable in water.

How to use
- Cleanse and tone as usual before this ampoule step.
- Dispense a small amount and press evenly over the face, avoiding the eye area.
- Allow it to fully absorb rather than layering the next step too soon.
- Follow with moisturizer, then a separate sunscreen in the morning.
Worth knowing
- Patch test on the inner arm before the first full-face application, especially on skin that reacts easily to new products.
- Stop use and rinse off if stinging, burning, or new redness shows up rather than pushing through discomfort.
