How it works
This sheet mask opens its ingredient list with Betaine, ahead of the rest of the formula, which is the clearest sign of what it is built around. Sodium Hyaluronate follows further down the list, part of the supporting cast rather than the headline. Purified Water follows further down the list, part of the supporting cast rather than the headline. That order is why SKIN1004 positions Centella Watergel Sheet Ampoule Mask as a sheet mask rather than a general moisturizer or cleanser: the concentration and format are built for the mask step, not for every step in a routine. It belongs in the mask step, once or twice a week after toner, left on for the stated time then peeled away and patted in.
Key benefits
- Size: 1ea, the Korean-market fill SKIN1004 sells inside Korea for this product.
- Led by Betaine: it sits at the top of this product's own ingredient list, the clearest read of what the formula is built around.
- Format: sheet mask, dosed and textured for the mask step rather than a general-purpose step.
- Routine slot: once or twice a week after toner, left on for the stated time then peeled away and patted in.
- Sourcing: shipped with the Korean-market barcode and batch code intact.
- Also on the list: Sodium Hyaluronate, one of the supporting ingredients behind the rest of the formula's texture and feel.
Inside the formula
Inside the formula
SKIN1004 Centella Watergel Sheet Ampoule Mask
Is the Centella Watergel Sheet Ampoule Mask sold here the Korean-market formula, not a US reformulation?
Yes. This listing is the release SKIN1004 sells for use inside Korea, the same formula Korean shoppers buy off the shelf there. A product with the same name can carry a different ingredient list or a different size in an export version, and we source and list only the Korean one, with that market's barcode and batch code intact on the unit that ships to you.
What is Betaine doing in this formula?
Betaine is the first ingredient of real substance on this product's own ingredient list, which puts it at the front of what the formula is built around rather than a trace addition. The rest of the list supports the texture and feel around it, in the concentration order the manufacturer itself declares.
Where does the Centella Watergel Sheet Ampoule Mask sit in a routine?
It occupies the mask step. Once or twice a week after toner, left on for the stated time then peeled away and patted in. Build a routine around the step you are replacing rather than the brand you recognize, since a handful of well-chosen steps tells you more about your skin than a shelf of unrelated products.
What size does the Centella Watergel Sheet Ampoule Mask ship in?
It ships at 1ea, the size SKIN1004 sells this product at inside Korea. We do not substitute an export format or a US-only size for the Korean one, so what you receive matches what a shopper buys for it in Seoul.
How can I check that my Centella Watergel Sheet Ampoule Mask is genuine?
Your unit ships with its Korean-market barcode and batch code intact.

27 of 29 explained
- Centellae Extract (51%) plant extract
- Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
- Purified 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Paeonia Suffruticosa Root Extract plant extract
- Paeonia Suffruticosa is tree peony, a long-standing East Asian medicinal plant. Its root extract carries paeoniflorin and is used for the look of reddened skin.
- 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.
- Matricaria Flower Extract plant extract
- Chamomile Flower Extract is one of the oldest ingredients in skincare, carrying bisabolol and chamazulene. It is used for the look of redness in formulas for reactive skin.
- Glyceryl Caprylate emulsifier
- Glyceryl Caprylate is a mild emulsifier that also makes a formula less hospitable to microbes, so it is often part of a preservative-free system.
15 more explained
- 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.
- 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.
- 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.
- 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.
- 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.
- Cacao Extract plant extract
- Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
- 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.
- Coptis Chinensis Root Extract plant extract
- Chinese goldthread root, a traditional herbal ingredient carrying berberine. It is bright yellow and is used in formulas aimed at the look of congested skin.
- 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.
- Hydrolyzed Glycosaminoglycans humectant
- Hydrolyzed Glycosaminoglycans are short fragments of the sugar chains that sit between cells in skin, hyaluronic acid among them. They act as humectants and give a cushioned feel.
- Benzyl Glycol preservative booster
- Benzyl Glycol is a solvent that also makes a formula less hospitable to microbes, so it appears in preservative blends built without parabens.
- 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.
- 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.
- 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.
- Rubus Idaeus Fruit Extract plant extract
- Raspberry fruit extract, carrying fruit acids, sugars and anthocyanins. It is used as an antioxidant-rich conditioning extract.
