Key actives
33Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. The panel names it thirty-third on this lip serum's list, beside Palmitoyl Tripeptide-1.
36Lactic 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 thirty-sixth on this lip serum's list, alongside Palmitoyl Tripeptide-1.
39Palmitoyl 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. It is the entry this lip serum is named after, and the list carries it.
44Sodium 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. The panel names it forty-fourth on this lip serum's list, beside Palmitoyl Tripeptide-1.
53Mentholactive
Menthol is the cooling compound in mint. It acts on the nerve receptor that also answers to cold, which is why skin feels cool without any change in temperature. The panel names it fifty-third on this lip serum's list, beside Palmitoyl Tripeptide-1.

COSRX 5 Peptide Collagen Tinted Lip Fill Treatment
Where does this lip serum go in my routine?
On clean lips, morning and evening, before any balm. Anything thinner than a lip serum 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 Palmitoyl Tripeptide-1 and not three changes at once.
Does this lip serum contain fragrance?
Yes. The ingredient list names Benzyl Benzoate, Citral, Fragrance and Limonene. 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 serum is not the one.
What else is on the list besides Palmitoyl Tripeptide-1?
Sodium DNA, Menthol and Gluconolactone. The order they are printed in on this lip serum's panel is the order on the box, so you can see where Palmitoyl Tripeptide-1 sits relative to them. Further down the same panel: Lactic Acid, Acetyl Hexapeptide-8 and Tripeptide-1.
Not on the ingredient list below: denatured or SD alcohol, silicones, parabens, sulfate surfactants and mineral oil or petrolatum.

53 of 55 explained
- 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.
- 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 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.
- 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.
- 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.
- OCTYLDODECANOL emollient
- Octyldodecanol is a branched fatty alcohol used as an emollient and as a solvent for pigments and mineral powders. It thickens slightly and leaves a soft finish.
- PENTAERYTHRITYL TETRAISOSTEARATE emollient
- A thick, cushioned ester that gives lip and balm formulas their gloss and their cling. It is heavy enough to stay where it is put.
- 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.
- 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.
- DISTEARDIMONIUM HECTORITE thickener
- Disteardimonium Hectorite is a modified clay used to thicken the oil phase and stop pigments settling to the bottom of the bottle.
- SILICA DIMETHYL SILYLATE absorbent
- Silica Dimethyl Silylate is silica with a silicone surface coating. It absorbs oil, thickens and stops powders clumping.
- 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.
41 more explained
- 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.
- POLYHYDROXYSTEARIC ACID dispersant
- A polymer of hydroxystearic acid whose whole job is keeping mineral powders and pigments evenly suspended in oil instead of settling or streaking.
- 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.
- LECITHIN emulsifier
- Lecithin is a soy or sunflower-derived phospholipid, the same class of molecule cell membranes are built from. It emulsifies oil into water and is the basis of the liposomes formulators use to carry actives.
- PROPYLENE CARBONATE solvent
- A polar solvent used mainly with clays: it swells montmorillonite and hectorite so they thicken an oil phase. It also thins heavy pigment pastes.
- 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.
- ISOSTEARIC ACID fatty acid
- Isostearic Acid is a branched fatty acid, so unlike stearic acid it stays liquid. It conditions and helps disperse pigments.
- ISOPROPYL MYRISTATE emollient
- Isopropyl Myristate is a light ester emollient that absorbs fast and helps other ingredients penetrate. It is known to be poorly suited to blemish-prone skin at higher levels.
- POLYGLYCERYL-3 POLYRICINOLEATE emulsifier
- Polyglyceryl-3 Polyricinoleate is a castor-derived emulsifier that lets a formula hold a high water content inside an oil or wax base.
- POLYGLYCERYL-2 TRIISOSTEARATE emulsifier
- Polyglyceryl-2 Triisostearate is a water-in-oil emulsifier used in balms and rich creams, and a good pigment disperser.
- 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.
- 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.
- RED 28 LAKE (CI 45410) colorant
- Red 28 Lake is a bright pink-red dye fixed onto a mineral base. It is the colour behind the stains that deepen on contact with 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- CITRUS LIMON (LEMON) PEEL OIL fragrance
- Cold-pressed lemon peel oil. Citrus peel oils carry limonene and can make skin more sensitive to sunlight, which is why leave-on formulas use them sparingly.
- BENZYL BENZOATE fragrance component
- Benzyl Benzoate is a faintly balsamic aromatic that also acts as a fixative, holding a fragrance on skin longer. It is one of the 26 declarable fragrance components.
- LIMONENE fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
- MENTHOL active
- Menthol is the cooling compound in mint. It acts on the nerve receptor that also answers to cold, which is why skin feels cool without any change in temperature.
- PINENE fragrance component
- Pinene is the terpene that makes pine and rosemary smell the way they do. On a label it is an aromatic plant constituent rather than a functional ingredient.
- CITRAL fragrance component
- Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.

How it works
The 5 Peptide Collagen Tinted Lip Fill Treatment is a lip serum, used on clean lips, morning and evening, before any balm. The peptide it is built around is Palmitoyl Tripeptide-1, named thirty-ninth on its own ingredient list. The same list carries Sodium DNA, Menthol and Gluconolactone, so the peptide is not the only thing on it worth naming. How much of the Palmitoyl Tripeptide-1 stays on the skin, and for how long, is decided by the lip serum format rather than by the list alone. COSRX sells this Palmitoyl Tripeptide-1 lip serum in Korea, and this is that version.
How to use
- Use the 5 Peptide Collagen Tinted Lip Fill Treatment on clean lips, morning and evening, before any balm.
- A single pass over each lip. Let it settle for a moment before anything goes over it.
- It goes on under a balm, which is the layer that keeps it in place.
- Twice a day. Do not use it on broken or cracked lips; wait until the surface is intact.
Worth knowing
- Patch test this lip serum on a small area and wait a day before using it more widely, especially with Palmitoyl Tripeptide-1 on the list.
- This list names Benzyl Benzoate, Citral and Fragrance, so skip it if fragrance components are something you avoid.
- Gluconolactone and Lactic Acid on this list makes this lip serum an exfoliating step, so do not stack it with another one on the same night.
