How it works
Round Lab 1025 Dokdo Water Gel Mask Sheet 10ea is built as a sheet mask, so its texture and finish are designed around one specific place in a routine rather than several. Round Lab, TIRTIR and Torriden formulate this kind of sheet mask to feel consistent with the rest of the brand's line, so the texture and absorption speed match what the format is meant to do. The texture is built for use as an occasional treatment step, after cleansing and toner, before your regular serum or moisturizer, which is why it behaves differently on skin than a product meant for a different point in a routine. This is the Korean-market formula of the 1025 dokdo water gel mask sheet 10ea, the version sold on shelves in Korea rather than a formula reworked for a different market.
Key benefits
- 1025 Dokdo Water Gel Mask Sheet 10ea is Round Lab's sheet mask, sourced for the Korean market rather than reformulated for US shelves.
- Carries Hyaluronic Acid, which is the water-binding polymer most Korean hydration formulas are built around.
- Carries Sodium Hyaluronate, which is a salt-form humectant from the hyaluronan family, smaller and faster-absorbing than the parent molecule, and a staple of Korean hydration formulas.
- Carries Allantoin, which is a calming, skin-conditioning agent frequently paired with soothing botanicals in Korean formulas.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.
- Suited to shoppers targeting dehydration and a compromised moisture barrier.
How to use
- Use Round Lab 1025 Dokdo Water Gel Mask Sheet 10ea once or twice weekly. Apply one full sheet unfolded and pressed onto the face, left on for ten to twenty minutes, then removed and pressed in rather than rinsed off. It goes as an occasional treatment step, after cleansing and toner, before your regular serum or moisturizer.
Is this the same formula sold in Korea, or a version made for the US market?
This is the Korean-market formula, the same one sold on shelves in Korea, not a separate version reformulated for US retail. The pack you open matches what a shopper in Seoul buys.
Where does this step go in a routine?
It belongs as an occasional treatment step, after cleansing and toner, before your regular serum or moisturizer. Placing it earlier or later than that changes how it feels going on and how well the steps after it absorb, so keeping it in that order is worth doing even on a simplified routine.
Can I use this if my skin runs sensitive?
This sheet mask is formulated with skin types like normal skin, dry skin in mind, but any new product is worth a patch test first if your skin reacts easily. A short patch test on the inside of your arm or behind an ear is worth doing with any new product before it goes on your face, and that goes for sensitive skin most of all.
How long before I will know if this is right for my skin?
Give it a full week or two of consistent use before judging, since a single use rarely tells you much either way. Watch for how skin feels rather than for any specific number, and stop use if you notice ongoing irritation.

Ingredient list read from inkeedecoder.com on 10 September 2026.
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.
- 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.
- Sea Water mineral
- Sea Water is filtered and desalinated seawater used in place of plain water. It carries magnesium, calcium and potassium, so it brings the mineral balance of the base closer to skin's own.
- Hydroxypropyltrimonium Hyaluronate humectant
- Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
- Sodium Acetylated Hyaluronate humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
- 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.
- 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.
- 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.
- Potassium Hyaluronate humectant
- Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.
22 more explained
- 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.
- Protease active
- Protease is an enzyme that breaks down protein. In a cleanser or peel it loosens the protein bonds holding dead surface cells together, which is a gentler route to smoothness than an acid or a scrub.
- Leucine amino acid
- Leucine is an essential amino acid used as a humectant, part of the amino acid block many Korean essences carry.
- Lysine amino acid
- Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.
- Phenylalanine amino acid
- Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
- Tryptophan amino acid
- Tryptophan is an essential amino acid. On a label it is usually one of a set of amino acids added together as a conditioning, water-holding blend.
- Valine amino acid
- Valine is an essential amino acid used as a humectant alongside the rest of an amino acid block.
- Threonine amino acid
- Threonine is an essential amino acid used in skincare as a humectant, normally as part of an amino acid complex rather than alone.
- Isoleucine amino acid
- Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
- Methionine amino acid
- Methionine is a sulphur-bearing essential amino acid used as a humectant and mild antioxidant.
- 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.
- 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.
- 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.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- Glucose humectant
- Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
- Xylitylglucoside humectant
- Xylitylglucoside is a sugar-derived humectant, the third member of the xylitol blend. Together the three hold water in the outer layer for longer than any of them does alone.
- Anhydroxylitol humectant
- Anhydroxylitol is a xylitol derivative used as a humectant. It is almost always part of the xylitol, anhydroxylitol and xylitylglucoside blend sold as a moisture-retention complex.
- Xylitol humectant
- Xylitol is a sugar alcohol humectant. It holds water in the outer layer of skin and is often paired with anhydroxylitol and xylitylglucoside as a hydration trio.
- 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.
- Sodium Phytate chelator
- Sodium Phytate is a rice-derived chelator used in place of EDTA. It ties up trace metals so the formula stays stable and its colour and scent hold.
- 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.

Worth knowing
- Remove the sheet before it dries out completely, since a fully dried sheet can pull moisture back out of skin rather than leaving it behind.
- Press the leftover essence into skin rather than rinsing it away, so the formula is not wasted after the sheet comes off.
