Key actives
14Allantoinactive
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. It is named fourteenth on this lip balm's list, alongside Palmitoyl Tripeptide-1.
17Madecassosideactive
Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams. It is named seventeenth on this lip balm's list, alongside Palmitoyl Tripeptide-1.
22Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. The panel names it twenty-second on this lip balm's list, beside Palmitoyl Tripeptide-1.
27Palmitoyl 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 name on the box points at it, and it is named twenty-seventh on this lip balm's own ingredient list.
32Sodium 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 thirty-second on this lip balm's list, beside Palmitoyl Tripeptide-1.

COSRX 5 Peptide B5 Sensitive Repair Salve Lip Balm
Where does this lip balm go in my routine?
On clean lips, at any point in the day and again as the last thing before bed. Anything thinner than a lip balm 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.
What else is on the list besides Palmitoyl Tripeptide-1?
Allantoin, Madecassoside and Sodium DNA. The order they are printed in on this lip balm'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: Gluconolactone, Lactic Acid and Acetyl Hexapeptide-8.

35 of 37 explained
- CAPRYLIC/CAPRIC TRIGLYCERIDE emollient
- Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
- 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.
- HYDROGENATED VEGETABLE OIL occlusive
- Plant oil hardened by hydrogenation. It behaves as a soft solid, so it gives balms and sticks their body and slows water loss from the surface.
- 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.
- SILICA DIMETHYL SILYLATE absorbent
- Silica Dimethyl Silylate is silica with a silicone surface coating. It absorbs oil, thickens and stops powders clumping.
- GLYCINE SOJA (SOYBEAN) STEROLS emollient
- The sterol fraction of soybean oil. Plant sterols are structurally close to the cholesterol in skin's own lipid layer, so they soften and help the oil phase hold together.
- 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.
- 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.
- 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.
- 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.
- 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.
23 more explained
- 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.
- 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.
- MADECASSOSIDE active
- Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams.
- 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.
- 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.
- 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.
- 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.

How it works
The 5 Peptide B5 Sensitive Repair Salve Lip Balm is a lip balm, used on clean lips, at any point in the day and again as the last thing before bed. The peptide it is built around is Palmitoyl Tripeptide-1, named twenty-seventh on its own ingredient list. The same list carries Allantoin, Madecassoside and Sodium DNA, 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 balm format rather than by the list alone. COSRX sells this Palmitoyl Tripeptide-1 lip balm in Korea, and this is that version.
How to use
- Use the 5 Peptide B5 Sensitive Repair Salve Lip Balm on bare lips, through the day and last thing at night.
- A thin layer by day, a thick one before bed, taken right up to the lip line.
- Nothing goes over it, and whatever is left on the fingertip is worth using on dry cuticles.
- As often as lips ask for it. Do not lick or blot it off; a salve only works while it is still in place.
Worth knowing
- Patch test this lip balm on a small area and wait a day before using it more widely, especially with Palmitoyl Tripeptide-1 on the list.
- Gluconolactone and Lactic Acid on this list makes this lip balm an exfoliating step, so do not stack it with another one on the same night.
