What makes this a hydration-focused serum rather than a treatment serum?

Ectoin and a multi-form hyaluronic acid complex, sodium hyaluronate, hydrolyzed sodium hyaluronate and glyceryl glucoside among them, carry the hydration argument, while niacinamide handles tone support. Centella asiatica extract and its purified compounds round out a calming layer rather than a heavier active treatment, which is why VT positions this as an everyday hydration step.

How thick is the texture?

The texture runs watery and light, closer to an essence than a heavy serum, and settles into a dewy rather than sticky finish. That thin consistency is why it is designed as the first liquid step after cleansing, moving into skin quickly rather than sitting on the surface.

Can this be used twice a day?

Yes, the formula is gentle enough for twice-daily use, meant as the first liquid step after cleansing whether that is a morning or evening routine. It suits anyone chasing plumper, better-hydrated skin without a heavy layering routine on top.

What is the bottle size?

This comes in a 50 ml bottle, the size sold in the Korean market. It is sized for regular twice-daily use as the first liquid step after cleansing rather than as a small trial or travel format, so a single bottle covers a normal serum-length rotation.

Does this contain any exfoliating or silica micro-spicules texture like other Reedle Shot products?

No, this Hydrop version is built around water and moisture rather than the textured feel found in some of VT's other Reedle Shot serums. The ingredient list carries no silica micro-spicules, so the emphasis stays on hydration rather than texture work.

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

9Panthenoltenth 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 tenth among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Panthenol

10Trehalose11th on the list, humectant

Trehalose is a sugar-derived humectant that supports moisture retention and helps a formula feel less drying over repeat use. Listed 11th among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

VT Cosmetics Hydrop Reedle Shot 300hL

46 of 47 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.
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.
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.
Hydroxyethyl Urea humectant: Hydroxyethyl Urea is a humectant that holds a lot of water for its size and stays comfortable at high levels. It is used where a formula needs to feel deeply hydrating without oil.
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.
Trehalose humectant: Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
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.
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.

34 more explained

Allantoin active: Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
C12-14 Alketh-12 emulsifier: C12-14 Alketh-12 is a solubiliser used to keep oils and fragrance dissolved in a water-based formula.
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.
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.
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.
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.
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.
Glyceryl Acrylate/Acrylic Acid Copolymer film former: This is a polymer that forms a moisture-holding film on the surface, usually supplied with glycerin and propylene glycol as a hydrating complex.
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.
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.
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.
Glyceryl Glucoside humectant: Glyceryl Glucoside is glycerin bound to glucose, from the resurrection plant. It is a humectant that holds water in the outer layer of skin.
PVM/MA Copolymer film former: PVM/MA Copolymer is a film-forming polymer used to hold a formula in place and, in a mask, to give the peel-off film its strength.
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.
Phenyl Trimethicone silicone: Phenyl Trimethicone is a silicone with a higher refractive index than most, so it adds visible gloss as well as slip. It is common in glow and lip textures.
Coccinia Indica Fruit Extract plant extract: Coccinia Indica is ivy gourd. Its fruit extract is used as a conditioning, hydrating plant extract in Korean formulas.
Polyglyceryl-10 Laurate emulsifier: Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
Polyglyceryl-10 Myristate emulsifier: Polyglyceryl-10 Myristate is a mild sugar-derived emulsifier used to keep oil dispersed in a watery formula.
Hydrolyzed Sodium Hyaluronate 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.
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.
Solanum Melongena (Eggplant) Fruit Extract plant extract: Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
Ectoin humectant: Ectoin is a small molecule that microbes in salt flats and hot springs make to survive extreme conditions. In skincare it holds water tightly around itself, which is why it appears in formulas aimed at reactive, easily dehydrated skin.
Ocimum Sanctum Leaf Extract plant extract: Ocimum Sanctum is holy basil, or tulsi. Its leaf extract carries plant antioxidants and is used in formulas built for the look of stressed, reactive skin.
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.
Corallina Officinalis Extract plant extract: Corallina Officinalis is coral seaweed, which holds calcium and magnesium in its structure. Its extract is used as a mineral-rich conditioning ingredient.
Curcuma Longa (Turmeric) Root Extract plant extract: Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
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.
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.
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.
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.
Decapeptide-40 peptide: Decapeptide-40 is a peptide of ten amino acids. The number identifies one sequence among many of the same length and says nothing about amount.

How it works

This hydration-focused serum is built around ectoin and a multi-form hyaluronic acid complex, including sodium hyaluronate, hydrolyzed sodium hyaluronate and glyceryl glucoside, with niacinamide for tone support. Centella asiatica extract and its purified compounds, madecassoside, madecassic acid, asiaticoside and asiatic acid, add a calming layer alongside panthenol and trehalose. The texture runs watery and light, closer to an essence than a heavy serum, and settles into a dewy rather than sticky finish. Used as the first liquid step after cleansing, it suits anyone chasing plumper, better-hydrated skin without a heavy layering routine, and is gentle enough for twice-daily use. The 50 ml bottle is the size sold in the Korean market.

How to use

Use it after cleansing, before the rest of your leave-on steps.
Two or three drops over the face, worked in and then pressed.
Layer your usual hydrators over the top while skin is still damp.
Do not run it with a second Reedle Shot in the same routine.

Worth knowing

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