How it works
The name on this bottle points at collagen, but the list points somewhere else first: niacinamide is entry three, ahead of every collagen-related ingredient that follows. Collagen Water and Milk Protein Extract appear at entries twenty-four and twenty-five, and Collagen Extract itself is declared at a vanishingly small 0.002 ppm, so the collagen story here rests on the water base and the milk protein rather than a marketing amount of pure collagen. Madecassoside, madecassic acid, asiaticoside and asiatic acid, the purified cica quartet, close the list. Massage over the face until the tingle fades, press in, and build frequency as tolerated.
Key benefits
- Niacinamide, entry three, carries real early weight
- Collagen Water and Milk Protein Extract sit at entries twenty-four and twenty-five: real, but not the largest part of the formula
- Collagen Extract itself is declared at 0.002 ppm, a small fraction, so we are naming that limit rather than leaning on the word collagen alone
- Madecassoside, madecassic acid, asiaticoside and asiatic acid, the purified cica quartet, close the list
- The '100' in the name marks the entry tier of VT's Reedle Shot ladder, the strength to start with before 300 or 700
Inside the formula
Inside the formula
VT Cosmetics Collagen Reedle Shot 100
How much collagen is actually in this serum?
Collagen water and milk protein extract sit at entries twenty-four and twenty-five on the ingredient list, real ingredients at a real position, but not the largest part of the formula. Collagen extract itself is declared at just 0.002 ppm, a small fraction worth knowing before buying on the name alone.
What is the lead active on this serum's ingredient list?
Niacinamide is entry three, the earliest and largest active named, giving this serum real tone support ahead of the collagen ingredients its name references. That early placement is the strongest signal the list gives about which ingredient does the most work in the formula.
What does the 100 mean in Collagen Reedle Shot 100?
The 100 marks the entry tier of VT's Reedle Shot ladder, the strength to start with before stepping up to 300 or 700. It refers to the formula's position in that numbered range rather than a percentage or dose figure.
What keeps this serum calm despite the tingling texture?
The purified centella cica quartet, madecassoside, madecassic acid, asiaticoside and asiatic acid, closes the ingredient list to keep the session calm. Adenosine also appears mid-list as the anti-aging signal ingredient carried alongside the calming compounds.
Is this serum fragrance-free?
Yes, no added fragrance appears on the ingredient list, consistent with the lighter, water-gel texture this 100-tier Reedle Shot product is built around. That makes it a reasonable choice for anyone who prefers to keep scent out of an entry-level ampoule.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

31 of 31 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Sodium Polyacrylate thickener
- Sodium Polyacrylate is a polymer that absorbs many times its weight in water. It thickens a formula and holds water in a gel against the skin.
- Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is a pre-neutralised polymer thickener that gels on contact with water and stabilises an emulsion without heat.
- Polyisobutene film former
- Polyisobutene is a synthetic polymer that forms a flexible, water-resistant film. It gives gloss and holds a formula in place, which is why it appears in lip products and long-wear textures.
- 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.
19 more explained
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Caprylyl/Capryl Glucoside surfactant
- Caprylyl/Capryl Glucoside is a sugar-derived cleansing surfactant. It foams modestly and is mild enough for low-pH cleansers built for reactive skin.
- Sorbitan Oleate emulsifier
- Sorbitan Oleate is an emulsifier for water-in-oil formulas. It keeps a rich cream or a cleansing oil from separating.
- 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.
- 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.
- Collagen Water (Water, Collagen) protein
- Collagen Water is a collagen solution used in place of plain water as a formula base. It hydrates and leaves a conditioned feel; the collagen molecule itself stays on the surface.
- Milk Protein Extract protein
- Milk Protein Extract supplies milk proteins and the lactose alongside them. It is used as a conditioning, water-holding ingredient.
- Collagen Extract (0.002ppm) protein
- Collagen Extract is a collagen-bearing extract, usually from fish skin or scales. In a formula it works as a humectant and a smoothing film rather than as a source of new collagen.
- 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.
