How it works
A hydrogel sheet is a delivery format rather than a formula type: the essence is set into a gel sheet so it stays against the face instead of evaporating off it. This is the hydrating mask in COSRX's 5 PDRN line, and it goes on after toner, in place of a serum step, in the evening. Sheet on, wait the time the pack gives, sheet off, then press in what is left rather than rinsing it away. Skin that looks flat and dry at the end of a long day is what a mask like this is for. Two or three evenings a week is a normal rhythm, as an addition to a routine rather than a replacement for one.
Key benefits
- Eight hyaluronate forms on the list, from hydrolyzed fragments to a crosspolymer, hydrate at layered depths
- Both sodium DNA and hydrolyzed DNA appear, the two DNA-derived ingredients behind the PDRN name
- Niacinamide sits fourth on the list for a fresher, more even look
- Centella asiatica extract and coptis japonica root extract carry the calming half of the formula
- The sheet turns visibly transparent as it warms against skin, a real cue that it has settled in
- Sold as three individually wrapped sheets, sized for one use each
Inside the formula
Inside the formula
COSRX 5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask
What does PDRN mean on this hydrogel mask's ingredient list?
PDRN is not a single named ingredient on Korean labels; it shows up here as Sodium DNA and, further down the list, Hydrolyzed DNA, the two DNA-derived materials the marketing name refers to. Both sit alongside adenosine and niacinamide, which is fourth on the list. Reading the box by its actual INCI names rather than the marketing shorthand is the only way to know what a PDRN product truly contains.
How many forms of hyaluronic acid are actually in this mask?
Eight separate hyaluronate entries run through the list: sodium hyaluronate, hydrolyzed hyaluronic acid, hydrolyzed sodium hyaluronate, hyaluronic acid itself, potassium hyaluronate, sodium hyaluronate crosspolymer, hydroxypropyltrimonium hyaluronate, and sodium acetylated hyaluronate. Each form differs in molecular weight and how it sits on or in the skin, which is why formulators layer several rather than relying on one.
Is this mask meant for daily use?
The mask is a sheet-format hydrogel meant for occasional, concentrated use rather than a daily step, since it is packaged and sold as individually wrapped sheets rather than a pump or jar. Leave it on until the gel turns visibly transparent against the skin, then pat in whatever is left. A few times a week is a reasonable starting cadence for most skin.
Does this mask contain fragrance or added scent?
No parfum or fragrance appears anywhere on the ingredient list. The formula instead relies on the base hydrogel matrix, carob gum and agar among them, to carry the actives without a scent layered on top, which matters for anyone reacting to added fragrance in leave-on products.
What is niacinamide doing in a hydrating mask like this one?
Niacinamide sits fourth on the list, ahead of every hyaluronate form and the PDRN complex, a high position rather than a token afterthought. Niacinamide is widely used for a fresher, more even-looking complexion alongside its hydrating packmates here, and its high list position is a real formulation signal rather than a marketing claim.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

Ingredient list read from inkeedecoder.com on 10 September 2026.
40 of 41 explained
- Aqua/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.
- Acrylates Copolymer film former
- Acrylates Copolymer is a synthetic polymer that forms a film as the water leaves. It holds a formula in place, controls shine and helps a texture stay put.
- 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.
- 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.
- Ceratonia Siliqua (Carob) Gum thickener
- Carob Gum is a seed polysaccharide from the carob tree. It thickens a formula and gives a soft, cushioned body.
- Chondrus Crispus plant extract
- Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
- Agar thickener
- Agar is a seaweed polysaccharide that sets into a firm gel. It is the gelling agent behind jelly masks and thick sleeping packs.
- Sclerotium Gum thickener
- Sclerotium Gum is a fungal polysaccharide thickener. It gives a smooth, non-stringy gel and holds an emulsion stable.
- Potassium Chloride mineral
- Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.
- Sucrose humectant
- Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.
- 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.
28 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Sodium DNA active
- Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to.
- Alpha-Arbutin active
- Alpha-Arbutin is a plant-derived compound, related to the sugar-bound form found in bearberry, used for the look of dark spots and uneven tone. It is stable in water and works at skin-friendly pH.
- Cyanocobalamin vitamin
- Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin.
- Lactobacillus Ferment ferment
- Lactobacillus Ferment is the liquid left after lactobacillus bacteria have fermented a plant or milk substrate. It carries the small molecules the fermentation produced, including lactic acid and amino acids, and is used for the look of dull, uneven skin.
- Hydrolyzed Collagen protein
- Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
- Centella Asiatica Extract 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.
- Caprylyl Glycol preservative booster
- Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
- 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.
- 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.
- 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.
- 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.
- 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.
- Acetyl Hexapeptide-8 peptide
- Acetyl Hexapeptide-8 is a six-amino-acid peptide used for the look of expression lines, particularly around the eyes. It is the peptide sold under the name Argireline and is water soluble and stable.
- 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.
- 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.
- 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 DNA active
- Hydrolyzed DNA is DNA cut into short fragments so it dissolves and spreads. It is the same ingredient family as sodium DNA and polydeoxyribonucleotide, the one Korean formulas market as PDRN.

How to use
- Use the 5 PDRN Hyaluronic Acid Vital Hydrating Hydrogel Mask after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind, then go straight to your moisturizer.
- Two or three evenings a week. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Collagen here is not plant-derived, so this is not a vegan formula.
