Is the Red Booster Reedle Shot 300 on this page the Korean-market formula?

Yes. It is the release VT Cosmetics makes for sale inside Korea. The same product name can carry a different ingredient list or a different size in an export version, and we list only the Korean one. The Reedle Shot family is a Korean shelf phenomenon, sold in strengths a US listing usually stocks one rung of at a time.

Where does the Red Booster Reedle Shot 300 sit in a routine?

It occupies the concentrated serum and ampoule step. Build the routine around the step you are replacing rather than the brand you recognise: a cleanser, a hydrating toner, one serum and one moisturizer is a complete routine, and four products chosen carefully tell you more about your skin than ten bought at once.

What size is the Red Booster Reedle Shot 300?

50 ml. That is the size VT Cosmetics sells in Korea for this product; we do not substitute an export format or a US size for the Korean one.

How does buying the Red Booster Reedle Shot 300 here compare with a US retailer?

This is the unit built for the Korean market, with the Korean barcode and batch code intact on the box. A US listing carrying the same product name may be the export version and rarely tells you which one it is sending.

Key actives

5Niacinamidefifth on the list, tone and texture

Niacinamide is a tone and texture ingredient that shows up across most of VT's Reedle Shot line, doing brightening and surface-refining work rather than deep hydration. Listed fifth among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Niacinamide

20Melia Azadirachta (Neem) Leaf Extract21st on the list, clarifying

Melia Azadirachta (Neem) Leaf Extract is a botanical extract with a clarifying reputation, useful on formulas positioned for blemish-prone or oil-heavy skin. Listed 21st among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Melia Azadirachta Leaf Extract

23Adenosine24th on the list, fine-line and texture smoothing

Adenosine is a Korean-formulation staple recognised for smoothing fine lines and texture, common enough in domestic Korean skincare to be treated as a routine inclusion rather than a headline. Listed 24th among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Adenosine

29Centella Asiatica Extract30th on the list, whole-leaf calming botanical

Centella Asiatica Extract is a leaf-form botanical version of centella, distinct from the purified TECA acids and included here for its own calming reputation in Korean formulation. Listed 30th among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Centella Asiatica Extract

31Panthenol32nd on the list, soothing, moisture-binding

Panthenol is a soothing, moisture-binding ingredient (provitamin B5) that supports comfort on skin that is dry or freshly exfoliated. Listed 32nd among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

VT Cosmetics Red Booster Reedle Shot 300

45 of 45 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.
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.
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.
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.
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.
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.
Diethoxyethyl Succinate solvent: Diethoxyethyl Succinate is a solvent that helps water-resistant actives spread and sink in evenly. It also leaves a light, silky feel.
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.
Sodium Carbomer thickener: Sodium Carbomer is the pre-neutralised form of carbomer, so it gels on contact with water without a base being added. It gives the same clear gel texture.
C12-14 Alketh-12 emulsifier: C12-14 Alketh-12 is a solubiliser used to keep oils and fragrance dissolved in a water-based formula.
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.
Eclipta Prostrata Extract plant extract: Eclipta Prostrata is false daisy, long used in Ayurvedic and East Asian practice. Its extract is used as a conditioning plant extract, most often in scalp and hair formulas.

33 more explained

Ammonium Acryloyldimethyltaurate/VP Copolymer thickener: This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
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.
Theobroma Cacao (Cocoa) Extract plant extract: Cocoa Extract carries polyphenols and a little caffeine. It is used as an antioxidant plant extract and gives a faint warm tint.
Croton Lechleri Resin Powder plant extract: Dragon's blood, the deep red resin of an Amazonian tree, dried to a powder. It carries proanthocyanidins and forms a film on the surface.
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.
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.
Ammonium Polyacryloyldimethyl Taurate thickener: Ammonium Polyacryloyldimethyl Taurate is a polymer thickener that gels instantly and gives a light, silky body.
Melia Azadirachta Leaf Extract plant extract: Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone 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.
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.
Adenosine active: Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated.
Tromethamine pH adjuster: Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
Tetrahydroxypropyl Ethylenediamine pH adjuster: An alkaline base that also binds metal ions. It raises pH and helps keep a formula stable, so it does two jobs at once.
Disodium 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.
Malachite Extract mineral: Malachite is a green copper carbonate mineral. Its extract is used in a formula as a source of trace copper.
Moringa Oleifera Seed Oil emollient: Moringa Seed Oil is high in oleic acid and behenic acid and very stable. It is a conditioning emollient with a light, non-sticky 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.
t-Butyl Alcohol solvent: t-Butyl Alcohol is the bittering agent added to cosmetic ethanol so it cannot be drunk. It appears in tiny amounts alongside alcohol denat. and does no formulation work of its own.
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.
Arbutin active: Arbutin is the naturally occurring form of the same compound, from bearberry and related plants, used for the look of uneven tone. The alpha isomer is the more stable of the two.
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.
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.
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.
Hexylresorcinol active: Hexylresorcinol is a resorcinol derivative used for the look of dark spots and uneven tone. It is one of the stronger non-prescription tone ingredients.
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.
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.
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.
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.
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.
Glycosphingolipids barrier lipid: Glycosphingolipids are ceramide-family lipids carrying a sugar group. They belong to the same lipid structure between skin cells and are used to make a formula feel more conditioning.
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.
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.
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.

How it works

This stronger red booster serum is built around centella asiatica extract, panthenol and arbutin, the same lead actives as VT's Reedle Shot 100 red booster, plus hexylresorcinol as an additional named active. Ceramide NP, sodium hyaluronate and glycine round out the comfort and hydration side of the formula, while madecassoside, madecassic acid, asiaticoside and asiatic acid close out the calming layer. It is a deep red essence that spreads thin and sinks in without any tacky residue, and a light tingle on application is expected and fades quickly. This is meant to be used as an occasional PM step rather than nightly, alongside the rest of a routine, positioned as the stronger of VT's two red booster serums. The fragrance-free 50 ml bottle sits well under a moisturizer as the intensive layer of a night routine.

How to use

Use it after cleansing as the first leave-on step, in the evening.
Two or three drops over the face, worked in until it has absorbed.
Alternate evenings while skin gets used to the higher level.
Do not run it and the 100 in the same routine; one of them is the step.

Worth knowing

Propolis Extract is bee-derived, so this formula is not a vegan one.
