Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
What peptides are actually in this mask, beyond the name?
Two named peptides appear on the list: acetyl hexapeptide-8, positioned mid-list, and palmitoyl tripeptide-5, further down near the ceramide cluster. Both sit alongside hydrolyzed collagen, so the formula's plumping angle comes from this peptide-collagen pairing rather than a single ingredient.
Does this mask contain vitamin B12?
Yes, cyanocobalamin, a form of vitamin B12, appears past the midpoint of the ingredient list. It is a less typical inclusion in a hydrogel mask and sits in a supporting rather than headline position relative to niacinamide, which is fourth.
Is there anything in this formula for the skin barrier specifically?
Ceramide NP and ceramide NS both appear near the end of the list, alongside cholesterol and phytosphingosine, the same three-lipid pairing used in dedicated barrier creams. The amount implied by their list position is smaller than a barrier-focused moisturizer would carry, but it is a real inclusion rather than an absent one.
What makes this hydrogel mask different from COSRX's other hydrogel masks in the same line?
This mask's distinguishing ingredients are the two named peptides, acetyl hexapeptide-8 and palmitoyl tripeptide-5, alongside hydrolyzed collagen and cyanocobalamin, a form of vitamin B12. Other masks in the same carob-gum and agar hydrogel base share niacinamide fourth on the list but build their supporting ingredients around a different concern, so checking each mask's own list is the reliable way to pick between them.
How many sheets are in this pack and how are they stored?
The pack contains three individually wrapped hydrogel sheets, each sealed separately so unopened sheets are not exposed to air. Store the unopened pack at room temperature out of direct sun, and use each sheet promptly once its individual wrapper is opened.
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.

38 of 39 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.
- Erythritol humectant
- Erythritol is a sugar alcohol humectant with a faint cooling feel as it dissolves. It hydrates and helps a formula spread without tack.
- 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.
26 more explained
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Cetearyl Alcohol fatty alcohol
- Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
- 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.
- Stearic Acid fatty acid
- Stearic Acid is a saturated fatty acid from plant fats, and one of the three lipid classes skin's own barrier is built from. In a formula it thickens, stabilises the emulsion and can be turned into a soap-style cleanser by adding a base.
- 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.
- 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.
- 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.
- Acetyl Glucosamine active
- Acetyl Glucosamine is the sugar unit hyaluronic acid is built from. It is used as a humectant and, at higher levels, for the look of uneven tone, often paired with niacinamide.
- Ceramide NP barrier lipid
- Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
- 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.
- 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 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.
- Ceramide NS barrier lipid
- Ceramide NS is another of the ceramides skin makes for itself. It is used alongside NP and AP so a formula supplies a mixture rather than a single lipid.
- Palmitoyl Tripeptide-5 peptide
- Palmitoyl Tripeptide-5 is a fatted three-amino-acid peptide used for the look of firmness and fine lines. The palmitoyl tail is what lets it cross an oily surface.
- Phytosphingosine barrier lipid
- Phytosphingosine is the backbone every ceramide is built on, and skin uses it in its own lipid layer. In a formula it works with ceramides and cholesterol and also keeps the product stable against microbes.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.

How it works
A hydrogel mask holds a dose of essence against the face and stays where it is put for the whole wear time. This one carries niacinamide, panthenol, allantoin and adenosine, set in a gel built with chondrus crispus. It goes on after toner, in place of the serum step, and whatever stays on the skin afterwards is pressed in. Skin that looks tired and flat at the end of a long week is what a mask like this gets bought for. Two or three evenings a week, and it does not stand in for a moisturizer.
How to use
- Use the Peptide Collagen Lifting Glow 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 rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. 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.
