Key actives
36Ceramide NPbarrier 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. It is the entry this lip mask is named after, and the list carries it.
37Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. It is named thirty-seventh on this lip mask's list, alongside Ceramide NP.
40Lactic Acidexfoliant
Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry skin. It is named fortieth on this lip mask's list, alongside Ceramide NP.
43Palmitoyl Tripeptide-1peptide
Palmitoyl Tripeptide-1 is a short peptide with a fatty tail added so it can travel through the oily outer layer of skin. It is used for the look of firmness and is almost always paired with palmitoyl tetrapeptide-7. The panel names it forty-third on this lip mask's list, beside Ceramide NP.
48Sodium DNAactive
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. It is named forty-eighth on this lip mask's list, alongside Ceramide NP.

COSRX 5 Peptide Ceramide Barrier Comfort Lip Mask
Where does this lip mask go in my routine?
As the last thing before bed, on clean lips. Anything thinner than a lip mask goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Ceramide NP and not three changes at once.
Does this lip mask contain fragrance?
Yes. The ingredient list names Fragrance and Parfum. They sit on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this lip mask is not the one.
What else is on the list besides Ceramide NP?
Sodium DNA, Gluconolactone and Lactic Acid. The order they are printed in on this lip mask's panel is the order on the box, so you can see where Ceramide NP sits relative to them. Further down the same panel: Palmitoyl Tripeptide-1, Acetyl Hexapeptide-8 and Tripeptide-1.
Not on the ingredient list below: denatured or SD alcohol, essential oils, parabens, sulfate surfactants and mineral oil or petrolatum.

47 of 54 explained
- DIISOSTEARYL MALATE emollient
- Diisostearyl Malate is a thick, glossy ester used to hold pigment in suspension and give a cushioned shine. It is the standard emollient in lip products.
- HYDROGENATED POLYISOBUTENE emollient
- Hydrogenated Polyisobutene is a stabilised synthetic hydrocarbon used in place of mineral oil. It is an emollient that leaves a smooth, cushioned film.
- PHYTOSTERYL/ISOSTEARYL/CETYL/STEARYL/BEHENYL DIMER DILINOLEATE emollient
- This is a heavy plant-sterol ester used in balms and cleansing oils. It softens skin, holds pigment and gives a thick, cushioned glide.
- POLYBUTENE film former
- Polybutene is a thick, sticky synthetic liquid polymer. It supplies the tack in a spot patch and the cushioned shine in a lip product.
- HYDROGENATED POLY(C6-14 OLEFIN) emollient
- Hydrogenated Poly(C6-14 Olefin) is a synthetic hydrocarbon emollient. It gives a smooth, silicone-like glide and is completely stable, so it does not go rancid.
- MICROCRYSTALLINE WAX / CERA MICROCRISTALLINA / CIRE MICROCRISTALLINE occlusive
- Microcrystalline Wax is a fine-crystalled petroleum wax. It gives balms and sticks body and flexibility and holds oil from separating out.
- BUTYROSPERMUM PARKII (SHEA) BUTTER emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- ETHYLENE/PROPYLENE/STYRENE COPOLYMER thickener
- A rubbery hydrocarbon polymer used to thicken oil phases and stop pigments settling. It is common in lip and stick formulas.
- SYNTHETIC WAX occlusive
- Synthetic Wax is a purpose-built hydrocarbon wax used to structure balms and sticks. It is odourless and does not oxidise, unlike most natural waxes.
- SILICA absorbent
- Silica is finely milled mineral, essentially very pure sand. It absorbs oil, stops powders clumping and soft-focuses the look of pores and fine lines.
- FRAGRANCE / PARFUM fragrance
- Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
- ASTROCARYUM MURUMURU SEED BUTTER emollient
- Murumuru butter, pressed from the seed of an Amazonian palm. It is high in lauric and myristic acid, so it is firm at room temperature and melts on contact with skin.
35 more explained
- CANDELILLA WAX ESTERS occlusive
- Candelilla wax broken down and rebuilt as esters, which makes it softer and easier to spread than the raw wax. It is used to give balms body.
- TOCOPHERYL ACETATE antioxidant
- Tocopheryl Acetate is a stable vitamin E ester that skin converts to tocopherol. It is used as an antioxidant and a light emollient and holds up better than plain vitamin E in a formula.
- ETHYLENE/PROPYLENE COPOLYMER thickener
- A soft hydrocarbon polymer used to thicken oils into a gel and to keep a stick or balm from separating.
- 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.
- BUTYLENE/ETHYLENE/STYRENE COPOLYMER thickener
- A rubbery polymer that gels oils and gives a formula cushion and cling. It is usually declared alongside its ethylene/propylene/styrene partner.
- ETHYLHEXYL PALMITATE emollient
- Ethylhexyl Palmitate is a palm-derived ester used as a light emollient and a solvent for pigment. It gives a smooth, non-greasy slip.
- POLYGLYCERYL-2 TRIISOSTEARATE emulsifier
- Polyglyceryl-2 Triisostearate is a water-in-oil emulsifier used in balms and rich creams, and a good pigment disperser.
- DIMETHICONE silicone
- Dimethicone is the most used cosmetic silicone. It forms a breathable film that smooths the surface, slows water leaving skin, and gives the slip that makes a primer or cream feel silky. It is inert and does not penetrate.
- TRIBEHENIN emollient
- Glycerin joined to three behenic acid chains, giving a soft wax-like ester. It thickens an oil phase and leaves a cushioned rather than slippery feel.
- PENTAERYTHRITYL TETRA-DI-T-BUTYL HYDROXYHYDROCINNAMATE antioxidant
- This is a stabiliser that keeps the oils and fragrance in a formula from oxidising. Its job is the shelf life of the product rather than any effect on skin.
- WATER / AQUA / EAU 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.
- 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.
- YELLOW 6 LAKE (CI 15985) colorant
- Yellow 6 Lake is a synthetic orange-yellow dye fixed onto a mineral base so it cannot dissolve and bleed. It sits on the surface as a pigment.
- SQUALANE emollient
- Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
- SORBITAN ISOSTEARATE emulsifier
- Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
- RED 6 (CI 15850) colorant
- Red 6 is a synthetic blue-red dye used as a lip and cheek colour. Its laked form, anchored to a mineral base, is declared as Red 7 Lake.
- 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.
- GLUCONOLACTONE exfoliant
- Gluconolactone is a PHA, the gentlest exfoliant class. Its molecule is too large to penetrate quickly, so it smooths the surface without the sting of an AHA, and it is a humectant at the same time.
- 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.
- 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.
- LACTIC ACID exfoliant
- Lactic Acid is a larger AHA than glycolic, so it works nearer the surface and is easier on skin, and it is a humectant as well as an exfoliant. It is the AHA of choice for dry skin.
- 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.
- 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.
- PALMITOYL TRIPEPTIDE-1 peptide
- Palmitoyl Tripeptide-1 is a short peptide with a fatty tail added so it can travel through the oily outer layer of skin. It is used for the look of firmness and is almost always paired with palmitoyl tetrapeptide-7.
- BETA-GLUCAN polysaccharide
- Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
- ORYZA SATIVA (RICE) BRAN EXTRACT plant extract
- Rice bran extract, from the outer layer milled off white rice. Bran is the richest part of the grain, carrying ferulic acid, vitamin E and phytic acid.
- 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.
- 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.
- 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.
- SOLUBLE COLLAGEN protein
- Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.
- TRIPEPTIDE-1 peptide
- Tripeptide-1 is the copper-free version of the classic three-amino-acid peptide. It is used for the look of firmness in formulas that avoid copper's blue tint.
- PALMITOYL TETRAPEPTIDE-7 peptide
- Palmitoyl Tetrapeptide-7 is a four-amino-acid peptide with a fatty tail, used for the look of fine lines. With palmitoyl tripeptide-1 it forms the pairing sold as Matrixyl 3000.
- PALMITOYL HEXAPEPTIDE-12 peptide
- Palmitoyl Hexapeptide-12 is a fatted six-amino-acid peptide used for the look of firmness, usually as part of a multi-peptide blend.
- VANILLIN fragrance component
- Vanillin is the compound that makes vanilla smell of vanilla. It is used to scent a formula.

How it works
The 5 Peptide Ceramide Barrier Comfort Lip Mask is a lip mask, used as the last thing before bed, on clean lips. The barrier lipid it is built around is Ceramide NP, named thirty-sixth on its own ingredient list. The same list carries Sodium DNA, Gluconolactone and Lactic Acid, so the barrier lipid is not the only thing on it worth naming. How much of the Ceramide NP stays on the skin, and for how long, is decided by the lip mask format rather than by the list alone. COSRX sells this Ceramide NP lip mask in Korea, and this is that version.
How to use
- Use the 5 Peptide Ceramide Barrier Comfort Lip Mask as the last thing before bed, on clean lips.
- A thick layer, more than you would use for a daytime balm, taken to the lip line and left there.
- It goes on after your evening routine is finished, and nothing goes over it.
- Nightly, or on the nights lips feel dry. Do not lick or blot it off before sleeping; it needs the whole night in place.
Worth knowing
- Patch test this lip mask on a small area and wait a day before using it more widely, especially with Ceramide NP on the list.
- This list names Fragrance and Parfum, so skip it if fragrance components are something you avoid.
- Gluconolactone and Lactic Acid on this list makes this lip mask an exfoliating step, so do not stack it with another one on the same night.

Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.

This means that gluconolactone acts as an exfoliating acid, but also as a moisturizer. It has moisturizing, soothing, and lightening properties, working well on dry skin.
