When do I use PDRN Reedle Shot Brush Hair Serum?

PDRN Reedle Shot Brush Hair Serum is a leave-in scalp step, applied to a clean, towel-dried scalp rather than rinsed out. Work it into your routine at that point rather than swapping it in for a different step, since the timing is part of how a Korean routine sequences a hair and scalp ampoule.

Is this the same formula sold in Korea?

Yes. This is the Korean-market VT Cosmetics release, imported with its original Korean-language packaging, barcode, and batch code intact, rather than a version reformulated or repackaged for US retail. We check that batch code against the one on the box before it ships, instead of relying on the listing alone.

Can I use PDRN Reedle Shot Brush Hair Serum on a sensitive scalp?

Patch test a small area of scalp before the first full application, and watch for redness or stinging over the following day. Menthol and fragrance are on the ingredient list.

Key actives

6Caffeinede-puffing feel

Caffeine is included here for the cooling, de-puffing feel it gives on contact, which is why Korean eye and scalp formulas reach for it first.

All products with Caffeine

25Centella Asiatica Extractcalming

Centella Asiatica Extract appears on this product's own ingredient list, and its calming fraction (Asiaticoside, Madecassoside, Madecassic Acid, Asiatic Acid) is also individually listed by name, the combination Korean skincare built the whole cica category around for stressed, freshly treated, or reactive-feeling skin.

All products with Centella Asiatica Extract

32Sodium Hyaluronatehydration

Sodium Hyaluronate is a smaller-molecule form of hyaluronic acid that draws in water at the surface, giving an immediate plumped, water-fresh feel rather than a heavy or greasy one.

All products with Sodium Hyaluronate

43Propolis Extractsoothing

Propolis Extract is a bee-derived resin ingredient with a long history in Korean beauty for a soothing, nourished feel, and this formula carries it well down its own ingredient list.

43 of 44 explained

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.
Alcohol Denat solvent: Alcohol Denat. is ethanol with a bitter additive that makes it undrinkable, which is a tax rule rather than a formulation choice. It behaves like alcohol: a fast-evaporating solvent that gives a weightless finish and can feel drying at higher levels.
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.
Glycereth-25 PCA Isostearate emollient: Glycereth-25 PCA Isostearate is a water-dispersible emollient that softens skin and helps oils and water stay mixed. It reads as light rather than rich on the skin.
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.
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.
Hydroxyacetophenone preservative booster: Hydroxyacetophenone is an antioxidant that also strengthens a preservative system, so a formula needs less traditional preservative. Korean formulas pair it with 1,2-hexanediol constantly.
Carbomer thickener: Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
Aminomethyl Propanol pH adjuster: Aminomethyl Propanol is an alkaline base used to raise pH and to neutralise acidic thickeners so they gel.
Hydroxyethylcellulose thickener: Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
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.
Pinus Sylvestris Leaf Extract plant extract: Scots pine needle extract. It carries pine terpenes and polyphenols and is used as a conditioning antioxidant extract.

Pentylene Glycol humectant: Pentylene Glycol hydrates and, like the other longer-chain glycols, makes a formula less hospitable to microbes so the preservative system can be lighter. It also improves how evenly a product spreads.
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.
Disodium Phosphate pH adjuster: Sodium Phosphate is a buffer salt. It holds a formula at a steady pH so its actives stay in the form they work in.
Polysorbate 60 emulsifier: Polysorbate 60 is a water-loving emulsifier used with a fatty co-emulsifier to build stable lotions and creams.
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.
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.
4-Terpineol fragrance component: A terpene alcohol, and the main constituent of tea tree oil. On a label it is an aromatic plant constituent rather than a functional ingredient.
Betaine humectant: Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
Epigallocatechin Gallate antioxidant: Epigallocatechin Gallate, usually written EGCG, is the main catechin in green tea and the compound most green tea claims rest on. It is used as a plant antioxidant.
Ginkgo Biloba Leaf Extract plant extract: Ginkgo leaf extract, carrying flavone glycosides and terpene lactones. It is one of the most studied plant extracts and is used as an antioxidant.
Silk Amino Acids amino acid: Silk protein broken down to its amino acids, mostly glycine, alanine and serine. They hydrate and leave a smooth, soft finish.
Centella Asiatica Extract plant extract: Centella Asiatica is the plant behind the whole cica category, sold as gotu kola or Madagascar centella. Its extract is the anchor of Korean formulas built for easily reddened skin, and its work is done by four triterpenes: asiaticoside, madecassoside, asiatic acid and madecassic acid.
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.
Chondrus Crispus (Carrageenan) Extract plant extract: Chondrus Crispus is Irish moss, a red seaweed. It is loaded with carrageenan, so it hydrates and thickens at once, and it leaves a cushioned, slippery film.
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.
Aloe Barbadensis Leaf Juice plant extract: Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient.
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.
Panax Ginseng (Mountain Ginseng) Extract plant extract: Ginseng Root Extract is the signature ingredient of Korean traditional skincare, carrying ginsenosides. It is used for the look of tired, dull skin, and brands often ferment it to break the ginsenosides into smaller forms.
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 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.
Xanthan Gum thickener: Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
Diatomaceous Earth absorbent: Diatomaceous Earth is fossilised algae shells, which are almost pure silica. It absorbs oil and works as a very fine polishing grain.
Tetrasodium Glutamate Diacetate chelator: A plant-derived chelator made from glutamic acid, used in place of EDTA. It binds the metal ions in water that would otherwise break a formula down.
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 (0.5ppb) 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.
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.
Madecassic Acid active: Madecassic Acid is the fourth centella triterpene. A list that names all four is telling you the extract was standardised rather than simply pressed, which is the difference between a cica claim and a cica formula.
Asiaticoside active: Asiaticoside is one of the four active triterpenes isolated from centella and the most studied of them. Korean formulas name it separately when they want to show which fraction of the plant they standardised.
Asiatic Acid active: Asiatic Acid is the third of centella's four triterpenes and the aglycone form, meaning it has no attached sugar. It is oil soluble, so it turns up in cica creams and balms more than in watery layers.
Propolis Extract plant extract: Propolis is the resin bees collect from tree buds and use to seal the hive. It is rich in flavonoids, carries a warm amber colour and scent, and is used for the look of dull, stressed skin. It is a bee product, so it is worth knowing about if you react to those.
Fragrance 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.

How it works

As a leave-in scalp ampoule, this product is designed to stay on the scalp rather than being rinsed out like a shampoo or conditioner. Applied directly to the scalp with its applicator tip, it reaches the roots more precisely than a hair product applied to the length of the hair. Massaging it in helps distribute the formula evenly and gives a momentary cooling or tingling feel depending on the ingredients. Left in rather than rinsed away, it continues sitting against the scalp between washes. Used consistently after shampooing, it becomes a small, repeated scalp step rather than a one-time treatment.

How to use

Use the PDRN Reedle Shot Brush Hair Serum after shampooing, on a towel-dried scalp.
Turn the brush head to the "ON" position to activate the product. Apply an appropriate amount of serum to the troubled areas of the scalp and gently massage in the direction of hair growth using the brush.
Leave it in rather than rinsing it out.

Worth knowing

Patch test on a small area of scalp before the first full application if your scalp is easily irritated.
Avoid applying to broken or actively irritated skin on the scalp until it has calmed down.
