Key benefits

- Ascorbic Acid on the same panel, the formula's antioxidant
- Korean-market formula, with its Korean barcode and batch code intact on the box
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.
193-O-Ethyl Ascorbic Acid
3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable.
23Ascorbic Acid
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.
24Tocopherol
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.

How is this sheet mask used in a routine?
Unfold the sheet and smooth it onto a cleansed face, adjusting it around the eyes, nose and mouth. Leave it on for 15 to 20 minutes, then remove and pat any remaining essence into the skin rather than rinsing it off. It works as an occasional, concentrated step layered over a completed routine, not a daily one.
Is this the same formula sold in Korea?
Yes. MEDIHEAL's Vitamin Derma Ampoule Mask 25ml X 10ea is sold here as the Korean-market formula, the same version carried in Korea, with intact Korean-market packaging and batch coding, not a US-shelf reformulation.
Who is this sheet mask suited for?
Normal skin, Dry or dehydrated skin are the best fit for this sheet mask. Patch test on the inner arm before first full use, as with any new skincare product.

Ingredient list read from medihealshop.com on 30 August 2026.
47 of 50 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Hydroxyacetophenone preservative booster
- Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
- Canola Oil emollient
- Canola Oil is pressed from rapeseed. It is a light, high-oleic oil used to soften skin and to carry oil-soluble ingredients.
- 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.
35 more explained
- 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.
- 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.
- Meadowfoam Seed Oil emollient
- Meadowfoam Seed Oil is over 95 percent long-chain fatty acids, which makes it exceptionally stable against going rancid. It is an emollient that leaves a soft, sealed feel.
- Polyglyceryl-4 Laurate emulsifier
- A short polyglycerin ester used as a mild emulsifier and cleansing agent. It is common in balms designed to melt on skin and then rinse away.
- Polyglyceryl-10 Stearate emulsifier
- Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
- 3-O-Ethyl Ascorbic Acid antioxidant
- 3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable.
- Argania Spinosa Kernel Oil emollient
- Argan Oil is pressed from the argan kernel and is rich in oleic and linoleic acids plus vitamin E. It is a medium-weight emollient that absorbs reasonably fast.
- Octyldodeceth-16 emulsifier
- An ethoxylated branched fatty alcohol. It emulsifies and also gives a formula a soft, cushioned slip.
- Trisodium Ethylenediamine Disuccinate chelator
- A readily biodegradable chelator used in place of EDTA. It ties up trace metal ions in the water so they cannot spoil the formula.
- 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.
- 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.
- Citrus Aurantium Bergamia 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.
- Pelargonium Graveolens Flower Oil fragrance component
- Pelargonium Graveolens is rose geranium. Its flower oil is an essential oil used to scent a formula, carrying citronellol and geraniol.
- Coptis Japonica Root Extract plant extract
- Coptis Japonica is a traditional East Asian medicinal root, bright yellow from its berberine content. In skincare its extract is used for the look of congested, oily skin.
- Lavandula Angustifolia Oil fragrance component
- Lavender Oil is an essential oil carrying linalool and linalyl acetate. It scents a formula, and linalool is one of the fragrance components EU labelling requires to be named separately.
- Hydrolyzed Corn Starch absorbent
- Hydrolyzed Corn Starch is starch broken into smaller fragments. It gives a silky, powdery slip and absorbs a little 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.
- Pantolactone humectant
- Pantolactone is a panthenol relative used as a conditioning humectant. It softens the outer layer of skin and helps a formula feel comfortable.
- 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.
- Arbutin active
- Arbutin is the naturally occurring form of the same compound, from bearberry and related plants, used for the look of uneven tone. The alpha isomer is the more stable of the two.
- Cyperus Rotundus Root Extract plant extract
- Nut grass root extract, a long used South Asian botanical. The tuber carries aromatic sesquiterpenes and flavonoids and is used as a conditioning extract.
- 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.
- Pantothenic Acid vitamin
- Pantothenic Acid is vitamin B5, the form skin converts panthenol into. It is used as a conditioning humectant that leaves skin feeling soft rather than tight.
- 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.
- 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.
- Pyridoxine vitamin
- Pyridoxine is vitamin B6. In a formula it is a conditioning vitamin, most often in B-complex blends and scalp products.
- 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.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- 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.
- Hesperidin antioxidant
- Hesperidin is the main flavonoid of citrus peel. It is used as a plant antioxidant and for the look of surface vessels.
- Riboflavin vitamin
- Riboflavin is vitamin B2, and it is a strong yellow, so a formula carrying it often has a colour nobody added on purpose.
- 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.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- 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.
- 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
Niacinamide leads the ingredient panel on this sheet mask. 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. On this panel it sits alongside 3-O-Ethyl Ascorbic Acid, Ascorbic Acid and Tocopherol. 3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable.
How to use
- Unfold the sheet and smooth it onto a cleansed face, adjusting it around the eyes, nose and mouth. Leave it on for 15 to 20 minutes, then remove and pat any remaining essence into the skin rather than rinsing it off.
Worth knowing

Using topical vitamin C can result in less cell damage and better-looking skin.
Melissa Piliang, MDDermatologist, Cleveland Clinic People with dry, flaky skin are more likely to see a benefit from using vitamin E because it enhances moisturization.

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.
