How it works
A rinse-out treatment gets a few minutes on the hair and nothing more, so where it goes matters as much as how long it stays. This is the treatment step in COSRX's PEPTIDE-132 range, spread through the mid-lengths and ends on hair towelled to damp rather than dripping. Water left in the hair is what stops a thick cream sitting in one place, and the scalp is left out of it on purpose. It follows the shampoo and comes before any leave-in or oil, once or twice a week rather than at every wash. Hair that feels rough from heat or color is the case a treatment step answers.
Key benefits
- Tripeptide-132, the bond-minded peptide the line is named for, is on the list
- Argan, olive, camellia, jojoba, rice bran and grape seed oils carry the gloss
- Oat peptide, soluble collagen and amino acids condition the lengths
- Rinses to silky, detangled hair without buildup

COSRX Peptide-132 Ultra Perfect Hair Bonding Treatment
What is this hair bonding treatment for?
This is a rich rinse-off conditioning cream built around tripeptide-132, listed among a run of six plant oils, argan, olive, camellia, jojoba, rice bran and grape seed, further down the ingredient list. Oat peptide and soluble collagen follow shortly after, adding a conditioning layer on top of the oil blend. It is meant to condition mid-lengths and ends rather than clean the scalp.
Will this feel too heavy for fine hair?
The base leans on dimethicone, cetyl alcohol and stearyl alcohol for slip and richness, so fine or easily weighed-down hair may prefer keeping it to the ends. No mineral oil, paraben or added colourant appears on the list. Applying it as directed, to damp mid-lengths and ends rather than the roots, is the way to manage that richness.
Does this treatment need repeated use to work, or is one application enough?
A rinse-off cream leaves behind only what the oils, silicones and tripeptide-132 deposit in the few minutes it sits on hair, so each wash builds on the last rather than resetting. Consistent use through the bottle, paired with the matching shampoo, is how a bond-support routine is meant to show up over time rather than after a single wash.
Can this be layered with a leave-in oil serum?
Yes, since this treatment rinses out before hair dries, a leave-in oil serum applied afterward to damp or dry hair is not competing with anything left behind by the rinse step. The treatment's own oils, argan and camellia among them, are formulated to mostly rinse away rather than remain on the surface.
How do I check this tube is genuinely Korean-market COSRX?
COSRX handles its own authentication: find the batch code and expiration date printed on your tube, then enter them on the verification page at cosrx.com rather than taking a seller's description at face value. That is the deliberate design of the check. The EAN for this size is 8809598457348.

Ingredient list read from jolse.com on 9 September 2026.
54 of 54 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.
- 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.
- Cetyl Ethylhexanoate emollient
- Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
- Isopentyldiol solvent
- Isopentyldiol is a glycol used as a light solvent and humectant. It thins a formula, keeps extracts dissolved and leaves a dry finish.
- Cetyl Alcohol fatty alcohol
- Cetyl Alcohol is a waxy fatty alcohol from coconut or palm, unrelated to drying ethanol. It thickens creams, stabilises the emulsion and leaves skin feeling softer.
- Stearyl Alcohol fatty alcohol
- Stearyl Alcohol is a solid fatty alcohol used to thicken and stabilise creams. Like the other fatty alcohols it is an emollient, not a solvent.
- Behentrimonium Chloride surfactant
- Behentrimonium Chloride is a positively charged conditioning agent. It is the main detangling ingredient in most hair conditioners, and it is not a cleanser.
- Coco-Caprylate/Caprate emollient
- Coco-Caprylate/Caprate is a coconut-derived ester used as a light, dry emollient in place of silicone. It spreads far and leaves a soft finish.
- Stearamidopropyl Dimethylamine surfactant
- A conditioning agent that takes on a positive charge in an acidic formula, so it clings to hair. It is used in place of a quaternary conditioner in silicone-free products.
- Sorbitol humectant
- Sorbitol is a sugar alcohol used as a humectant. It hydrates like glycerin with a smoother, less sticky finish, and it adds a little body to watery textures.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
42 more explained
- Dimethiconol silicone
- Dimethiconol is a high-molecular-weight silicone that leaves a longer-lasting smooth film than dimethicone. It is used for lasting slip and shine.
- Hydroxypropyl Starch Phosphate thickener
- Hydroxypropyl Starch Phosphate is a modified starch used to thicken and to take the sticky edge off a formula, leaving a powdery finish.
- Amodimethicone silicone
- A silicone carrying a positive charge, so it is drawn to damaged hair and stays after rinsing. It is a conditioning silicone rather than a slip agent.
- 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.
- Maltitol humectant
- Maltitol is a sugar alcohol humectant made from starch. It hydrates with a smooth, low-tack finish and adds a little body to a watery formula.
- 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.
- 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.
- Trideceth-10 emulsifier
- An ethoxylated fatty alcohol used as an emulsifier and solubiliser. It dissolves small amounts of oil or fragrance into a watery formula without clouding it.
- Sodium Gluconate chelator
- The sodium salt of gluconic acid, used to tie up trace metals so a formula stays stable. It is one of the gentler chelators.
- 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.
- Anthemis Nobilis Flower Water plant extract
- Roman chamomile distillate, used in place of plain water as a base. It is much more dilute than an extract, so it sets the base rather than supplying actives.
- 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.
- 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.
- Argania Spinosa Kernel Oil emollient
- Argan Oil is pressed from the argan kernel and is rich in oleic and linoleic acids plus vitamin E. It is a medium-weight emollient that absorbs reasonably fast.
- Olea Europaea (Olive) Fruit Oil emollient
- Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it.
- Camellia Japonica Seed Oil emollient
- Camellia Seed Oil is the traditional Korean and Japanese hair and skin oil, high in oleic acid. It is a light emollient that absorbs quickly for its richness.
- Simmondsia Chinensis (Jojoba) Seed Oil emollient
- Jojoba Oil is a liquid wax rather than a true oil, and its structure is close to human sebum, which is why it absorbs so readily. It is an emollient that leaves a soft, non-greasy finish.
- Oryza Sativa (Rice) Bran Oil emollient
- Rice Bran Oil is pressed from the bran left over from milling rice. It carries vitamin E and a group of rice-specific antioxidants, and it is a light emollient.
- Vitis Vinifera (Grape) Seed Oil emollient
- Grape Seed Oil is a light, linoleic-acid-rich oil with a fast, dry absorption. It is one of the plant oils used where an oil is wanted without a heavy finish.
- Biotin vitamin
- Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
- Tripeptide-132 HCl peptide
- Tripeptide-132 HCl is a three-amino-acid peptide supplied as a hydrochloride salt, which is simply the form that dissolves readily in water.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- 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.
- 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.
- Laminaria Japonica Extract plant extract
- Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
- Sodium Metaphosphate chelator
- A phosphate salt that ties up metal ions in water. It also stops the calcium and magnesium in hard water from flattening a cleanser foam.
- Avena Sativa (Oat) Peptide peptide
- Avena Sativa Peptide is oat protein cut into short fragments. Plant peptides behave as water-holding, film-forming proteins rather than as the signalling peptides of the numbered families.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Serine amino acid
- Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
- Glutamic Acid amino acid
- Glutamic Acid is an amino acid used as a humectant and a mild pH adjuster. It is one of the components of skin's natural moisturising factor.
- Threonine amino acid
- Threonine is an essential amino acid used in skincare as a humectant, normally as part of an amino acid complex rather than alone.
- Leucine amino acid
- Leucine is an essential amino acid used as a humectant, part of the amino acid block many Korean essences carry.
- Proline amino acid
- Proline is an amino acid abundant in collagen and one of skin's own humectants. Added to a formula it holds water in the outer layer.
- Aspartic Acid amino acid
- Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
- Isoleucine amino acid
- Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
- Glycine amino acid
- Glycine is the smallest amino acid and one of the free amino acids skin holds to keep water in the outer layer. In a formula it is a humectant and a mild buffer.
- 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.
- 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.
- Phenylalanine amino acid
- Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
- Alanine amino acid
- Alanine is a free amino acid skin uses as part of its own moisture-holding system. In a formula it hydrates and conditions.
- Tyrosine amino acid
- Tyrosine is an amino acid used as a conditioning humectant in amino acid complexes.
- Lysine amino acid
- Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.

How to use
- Use the PEPTIDE-132 Ultra Perfect Hair Bonding Treatment after shampooing, on hair towelled to damp rather than dripping.
- A generous amount through the mid-lengths and ends, kept off the scalp itself.
- Shampoo first, this second. Leave it for the time the pack gives, then rinse.
- Once or twice a week. Do not work it into the roots; a treatment weighs down the one part of the hair that does not need it.
Worth knowing
- Fragrance is on the ingredient list.
- This formula carries an active acid, so pairing it with another exfoliant in the same routine is worth spacing out.
- Collagen here is not plant-derived, so this is not a vegan formula.
