What does the Rosemary PDRN Cooling Thickening Shampoo 400ml actually contain?

Its ingredient list is led by Panthenol, with the rest of the formula built to support that active rather than compete with it. We list the ingredients in the order the manufacturer prints them, so the ones near the top of the panel are doing the most work in the formula.

How do I use the Rosemary PDRN Cooling Thickening Shampoo 400ml?

Use this shampoo as the cleansing step of a hair-care routine. To apply, work a coin-sized amount into wet hair and scalp, lather, and rinse thoroughly. Keep it to as often as the scalp needs washing unless the packaging states otherwise, and give the rest of the routine a moment to settle before layering the next step. Give it a full bottle or box before judging the result, since most Korean routines are built for steady use rather than a single application.

Is the Rosemary PDRN Cooling Thickening Shampoo 400ml the same formula sold in Korea, or a US version?

This Rosemary PDRN Cooling Thickening Shampoo 400ml is the Korean-market formula, not a version reformulated for US shelves. It arrives with its original Korean-market barcode and batch code intact so the formula can be checked against the box on arrival.

Can I use the Rosemary PDRN Cooling Thickening Shampoo 400ml with other actives in my routine?

Yes, as long as it is used in its own step, the cleansing step of a hair-care routine, and not layered on top of a product doing the same job. Introduce any new step gradually over the first week or two and keep an eye on how the skin responds before adding a second new active alongside it.

How it works

Medicube Rosemary PDRN Cooling Thickening Shampoo 400ml is a shampoo built for the cleansing step of a hair-care routine. Its ingredient list leads with Panthenol, Salicylic Acid, and Niacinamide, so the formula's stated purpose lines up with what actually sits near the top of that list rather than with a single marketing ingredient buried further down. Panthenol does the most work here as a comfort, and the remaining actives round out the texture and finish rather than compete for attention. Placed as the cleansing step of a hair-care routine, it is meant to be used as often as the scalp needs washing rather than swapped freely between steps. Because this is the Korean-market version of the Rosemary PDRN Cooling Thickening Shampoo 400ml line rather than a US-reformulated variant, the texture and finish match what Medicube sells through Korean retail.

Ingredient list read from stylekorean.com on 10 September 2026.

102 of 107 explained

Water (Aqua) 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.
Sodium Cocoyl Isethionate surfactant: Sodium Cocoyl Isethionate is a coconut-derived surfactant that gives a dense, creamy foam while staying mild. It is the usual choice in syndet cleansing bars.
Disodium Laureth Sulfosuccinate surfactant: A sulfosuccinate surfactant: milder than a sulfate, with more foam than an amino-acid one. It is often used to soften a sulfate-based cleanser.
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.
Cocamidopropyl Hydroxysultaine surfactant: A mild coconut-derived cleanser that carries both a positive and a negative charge. It foams well and is gentler than a sulfate.
Lauryl Betaine surfactant: Lauryl Betaine is a secondary surfactant that boosts foam and thickens a cleanser while reducing how stripping the main surfactant feels.
Glyceryl Stearate emulsifier: Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
Sodium Lauroyl Methylaminopropionate surfactant: An amino-acid-derived cleanser that foams well at skin-friendly pH. It is one of the mild surfactants Korean low-pH cleansers are built on.
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.
Trihydroxystearin thickener: A castor-derived wax used to thicken oils and stop pigments settling. It builds structure in an anhydrous formula without making it hard.
Sodium Chloride thickener: Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
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.

90 more explained

Sodium Benzoate preservative: Sodium Benzoate is a mild preservative that works only in acidic formulas. It is usually paired with potassium sorbate, and the pair is the standard choice where a brand wants no phenoxyethanol.
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.
Dicaprylyl Ether emollient: Dicaprylyl Ether is a very light emollient used to make a formula spread quickly and feel dry rather than oily.
Polyquaternium-10 film former: A cellulose polymer carrying a positive charge. It deposits from a rinse-off formula onto hair or skin and leaves a smooth, anti-static film.
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.
Salicylic Acid exfoliant: Salicylic Acid is a BHA, and the only common exfoliant that is oil soluble, so it can work inside a pore rather than only on the surface. It loosens the dead cells that block pores and is used for the look of congested, oily skin.
Citric Acid pH adjuster: Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
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.
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.
Tetrasodium EDTA chelator: EDTA is a chelator: it locks up trace metal ions from water and packaging that would otherwise turn a formula cloudy, off-colour or rancid. It does nothing to skin and appears at a fraction of a percent.
Zea Mays (Corn) Starch absorbent: Corn Starch absorbs oil and moisture and gives a soft, matte finish. It also thickens a formula.
Mannitol humectant: Mannitol is a sugar alcohol used as a humectant and antioxidant. It hydrates and helps stabilise the rest of the formula against oxidation.
Microcrystalline Cellulose absorbent: Microcrystalline Cellulose is purified cellulose ground fine. It thickens, holds powders in suspension and gives a soft, matte feel.
Linalool fragrance component: Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.
Carthamus Tinctorius (Safflower) Flower Extract plant extract: Safflower Flower Extract is a traditional East Asian dye and skincare plant. It is used as a conditioning antioxidant extract and can tint a formula.
Dextrin thickener: Dextrin is a starch fragment used to thicken and to give a formula a light, powdery finish. It is also a common carrier for powdered extracts.
Gardenia Florida Fruit Extract plant extract: Gardenia Fruit Extract is the traditional East Asian yellow dye plant. In skincare it is used as an antioxidant extract, and it can tint a formula.
Chromium Oxide Greens colorant: Chromium Oxide Greens is a dull green mineral pigment. It is inert, sits on the surface, and is used in small amounts to correct the look of redness in a tinted product.
Ultramarines colorant: Ultramarines are blue to violet mineral pigments. In skincare they are used in tiny amounts to shift a yellow-looking base back toward neutral.
Chromium Hydroxide Green colorant: A blue-green mineral pigment, brighter than chromium oxide greens. It is inert and sits on the surface.
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.
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.
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.
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.
Sodium Citrate pH adjuster: Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
Caffeine active: Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin.
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.
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.
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.
Menthyl Lactate active: Menthyl Lactate is a menthol derivative that gives a cooling sensation without menthol's sharpness or scent. It is a sensory ingredient rather than an active.
Ricinus Communis (Castor) Seed Oil emollient: Castor Oil is thick, glossy and unusually good at dissolving pigment, which is why it dominates lip and cleansing-balm formulas. It is a heavy emollient.
Glycolic Acid exfoliant: Glycolic Acid is the smallest AHA, which is why it is also the most penetrating and the most likely to sting. It loosens the bonds between dead surface cells and is used for the look of dullness and rough texture.
Saccharide Isomerate humectant: A plant-sugar complex whose structure resembles the sugars already bound to the skin surface, so it stays through washing. It is used as a long-acting humectant.
Sodium C14-16 Olefin Sulfonate surfactant: A strong anionic surfactant that foams heavily. It is a sulfate alternative in name but not in strength, and it is more common in shampoos than in facial cleansers.
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.
Hydrolyzed Pea Protein protein: Pea protein cut into small fragments so it dissolves in water. It is a plant protein used as a humectant and a light film former.
Hydrolyzed Vegetable Protein protein: Hydrolyzed Vegetable Protein is plant protein cut into water-soluble fragments. It forms a light conditioning film that holds water at the surface.
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.
Raphanus Sativus (Radish) Seed Extract plant extract: Radish seed extract. It is used as a conditioning plant extract, and radish-root ferment filtrate from the same plant is a common natural preservative.
Sodium Palmitoyl Sarcosinate surfactant: Sodium Palmitoyl Sarcosinate is an amino-acid-derived cleanser built on sarcosine. It foams well at skin-friendly pH, which is why Korean low-pH cleansers use it.
Octyldodecyl Oleate emollient: A large branched ester with a rich, cushioned feel. It is used in balms and lip products and helps disperse pigments.
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.
Sparassis Crispa Extract plant extract: Cauliflower mushroom extract, one of the richest natural sources of beta-glucan. It hydrates and leaves a soft film.
Streptococcus Thermophilus Ferment ferment: Streptococcus Thermophilus Ferment is a yoghurt-culture ferment. It is used for its conditioning effect on the outer layer of skin.
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.
Hydrolyzed Corn Protein protein: Hydrolyzed Corn Protein is corn protein cut into small soluble pieces. On a label it usually sits with two or three other plant proteins, because each brings a different amino acid balance.
Hydrolyzed Extensin protein: Extensin is a structural glycoprotein from plant cell walls. Hydrolysed, it is cut into fragments small enough to dissolve, and it works as a water-holding film on the surface.
Hydrolyzed Potato Protein protein: Potato protein cut into small fragments. It is a plant protein used as a humectant and light film former.
Hydrolyzed Rice Protein protein: Hydrolyzed Rice Protein is rice protein broken into small fragments. It is a humectant and film former that leaves a soft, smooth finish.
Hydrolyzed Soy Protein protein: Hydrolyzed Soy Protein is soy protein cut into water-soluble fragments. It conditions the surface and holds water, and it is one of the most used plant proteins in cosmetics.
Melaleuca Alternifolia (Tea Tree) Leaf Extract plant extract: Tea Tree Leaf Extract is the water-based extract rather than the essential oil, so it is far milder and much less aromatic. It is used in formulas for blemish-prone skin.
Potassium Sorbate preservative: Potassium Sorbate is a preservative that holds off yeast and mould in acidic formulas. It is almost always used with sodium benzoate, because neither covers the whole range of microbes alone.
Sodium DNA (2.5 ppb) 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.
Hydrolyzed Keratin protein: Hydrolyzed Keratin is keratin, the protein hair and nails are built from, cut into fragments small enough to dissolve. In a formula it is a humectant and a smoothing film former.
Rosmarinus Officinalis (Rosemary) Leaf Extract (0.25 ppb) plant extract: Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
Biotin vitamin: Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
sh-Oligopeptide-1 peptide: sh-Oligopeptide-1 is a peptide made by yeast fermentation rather than synthesis, which is what the sh prefix records. It is used for the look of firmness and skin recovery after irritation.
sh-Oligopeptide-2 peptide: sh-Oligopeptide-2 is a second fermentation-produced peptide, used alongside sh-oligopeptide-1 for the look of firmness.
sh-Polypeptide-1 peptide: sh-Polypeptide-1 is a longer fermentation-produced peptide. It is used in formulas built around the look of resilience and recovery.
sh-Polypeptide-11 peptide: sh-Polypeptide-11 is a fermentation-produced peptide. Korean formulas use the sh family in blends built around the look of resilience and recovery.
sh-Polypeptide-22 peptide: sh-Polypeptide-22 is another fermentation-produced peptide of the sh family, used in multi-peptide serums rather than on its own.
sh-Polypeptide-3 peptide: sh-Polypeptide-3 is a peptide made by fermentation rather than by chemical synthesis, which is what the sh prefix records. Polypeptide means a longer chain than a tri or hexapeptide.
sh-Polypeptide-9 peptide: sh-Polypeptide-9 is another fermentation-produced peptide used for the look of firmness, usually as part of a blend.
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.
Asparagine amino acid: Asparagine is an amino acid used as a humectant and conditioner, almost always inside a wider amino acid blend rather than on its own.
Aspartic Acid amino acid: Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
Dimethylsilanol Hyaluronate humectant: Dimethylsilanol Hyaluronate is hyaluronic acid joined to a silicon-based group. It hydrates and leaves a smoother, silkier finish than hyaluronic acid alone.
Glucose humectant: Glucose is a simple sugar used as a humectant and as food for the ferment ingredients in the same formula. It hydrates mildly and adds a soft slip.
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.
Glutamine amino acid: Glutamine is the most abundant free amino acid in the body. In a formula it hydrates and conditions, usually as part of an amino acid blend.
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.
Histidine amino acid: Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
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.
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.
Hydroxypropyltrimonium Hyaluronate humectant: Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
Isoleucine amino acid: Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
Leucine amino acid: Leucine is an essential amino acid used as a humectant, part of the amino acid block many Korean essences carry.
Lysine amino acid: Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.
Mentha Piperita (Peppermint) Leaf Extract plant extract: Peppermint leaf extract, the water-based extract rather than the essential oil, so it carries far less menthol. It is used as a refreshing herbal extract.
Methionine amino acid: Methionine is a sulphur-bearing essential amino acid used as a humectant and mild antioxidant.
Phenylalanine amino acid: Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
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.
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.
Sodium Acetylated Hyaluronate humectant: Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
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.
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.
Tryptophan amino acid: Tryptophan is an essential amino acid. On a label it is usually one of a set of amino acids added together as a conditioning, water-holding blend.
Tyrosine amino acid: Tyrosine is an amino acid used as a conditioning humectant in amino acid complexes.
Valine amino acid: Valine is an essential amino acid used as a humectant alongside the rest of an amino acid block.
