Is the Reti-A Reedle Shot 100 2Step Hydrogel Mask Set 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 Reti-A Reedle Shot 100 2Step Hydrogel Mask Set sit in a routine?

It occupies the mask 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.

How does buying the Reti-A Reedle Shot 100 2Step Hydrogel Mask Set 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

4Niacinamidefourth 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 fourth among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Niacinamide

19Allantoin20th on the list, soothing

Allantoin is a mild, well-tolerated soothing agent that rounds out a formula's calming profile without adding any fragrance-like irritation risk. Listed 20th among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Allantoin

22Adenosine23rd 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 23rd among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Adenosine

25Sodium Hyaluronate26th on the list, hydration

Sodium Hyaluronate is the salt form of hyaluronic acid, a lightweight humectant that draws and holds water at the skin's surface rather than sitting on top of it. Listed 26th among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

All products with Sodium Hyaluronate

28Centella Asiatica Extract29th 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 29th among the ingredients, it sits where the formula's own INCI order places its real weight in the mix.

VT Cosmetics Reti-A Reedle Shot 100 2Step Hydrogel Mask Set

57 of 59 explained

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.
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.
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.
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.
Dimethyl Isosorbide solvent: Dimethyl Isosorbide is a solvent used to dissolve actives that water and oil both reject, and to carry them evenly through the outer layer of skin. It appears in vitamin C and retinoid formulas for exactly that reason.
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 Isethionate (or Acryloyldimethyl Taurate) Copolymer thickener: A gelling copolymer that thickens water and stabilises an emulsion. It gives the light, quick-breaking gel texture Korean essences use.
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.
Polyglyceryl-6 Stearate emulsifier: Polyglyceryl-6 Stearate is a mild plant-derived emulsifier for oil-in-water creams.

45 more explained

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.
Hydroxypinacolone Retinoate active: Hydroxypinacolone Retinoate is a retinoid ester that binds skin's retinoid receptors directly, with no conversion step. Brands use it where they want retinoid-style results with less of the flaking retinol brings.
Retinol active: Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.
Bakuchiol active: Bakuchiol is a compound from the babchi seed, used as a plant-derived alternative to retinol. It is oil soluble, stable in daylight and does not carry retinol's acclimatisation period, which is why sensitive-skin formulas choose it.
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.
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.
Dipotassium Glycyrrhizate active: Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
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.
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.
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.
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.
Polysorbate 20 emulsifier: Polysorbate 20 is a solubiliser: it dissolves small amounts of oil or fragrance into a watery formula so nothing separates or floats.
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.
Beta-Carotene antioxidant: Beta-Carotene is an orange plant pigment and a vitamin A precursor. It is used as an antioxidant and it tints a formula, which is often why it is there.
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.
Diospyros Kaki Leaf Extract plant extract: Diospyros Kaki is the persimmon tree. Its leaf extract carries tannins and vitamin C and is used as an antioxidant extract.
Vitis Vinifera Fruit Extract plant extract: Grape Fruit Extract carries polyphenols and fruit acids. It is used as an antioxidant plant extract.
Coffea Arabica Seed Extract plant extract: Coffee Seed Extract carries caffeine and chlorogenic acid. It is used as an antioxidant extract and, in eye and body formulas, for the look of puffiness.
Carthamus Tinctorius 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.
Polygonum Cuspidatum Root Extract plant extract: Polygonum Cuspidatum is Japanese knotweed, the main commercial source of resveratrol. Its root extract is used as an antioxidant plant extract.
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.
Castanea Crenata Shell Extract plant extract: Chestnut Shell Extract carries tannins and is used as an antioxidant plant extract, most often in formulas aimed at visible pores.
Camellia Sinensis Leaf Extract plant extract: Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
Zanthoxylum Piperitum Fruit Extract plant extract: Zanthoxylum Piperitum is Korean pepper. Its fruit extract is used as a conditioning plant extract and is often paired with pulsatilla and usnea in Korean formulas.
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.
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.
PEG-100 Stearate emulsifier: PEG-100 Stearate is a water-loving emulsifier almost always paired with glyceryl stearate. Together they form the standard cream base of the last fifty years.
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.
Ceratonia Siliqua Gum thickener: Carob Gum is a seed polysaccharide from the carob tree. It thickens a formula and gives a soft, cushioned body.
Chondrus Crispus (Carrageenan) Powder & 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.
Cellulose Gum thickener: Cellulose Gum is plant cellulose modified to dissolve in water. It thickens, holds particles in suspension and gives a smooth, slippery body.
Shea Butter emollient: Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
Chamomilla Recutita Flower Extract plant extract: Chamomile Flower Extract is one of the oldest ingredients in skincare, carrying bisabolol and chamazulene. It is used for the look of redness in formulas for reactive skin.
Hydrogenated Polydecene emollient: Hydrogenated Polydecene is a synthetic hydrocarbon emollient used in place of mineral oil. It is stable, has no scent, and gives a cushioned slip without oxidising.
Sucrose humectant: Sucrose is table sugar, used here as a humectant. It draws water into the outer layer of skin and, in a scrub, doubles as the physical grain.
Trideceth-6 emulsifier: Trideceth-6 is a solubiliser used to dissolve fragrance and oil-soluble ingredients into a watery formula so it stays clear.
Pantolactone humectant: Pantolactone is a panthenol relative used as a conditioning humectant. It softens the outer layer of skin and helps a formula feel comfortable.
Hydrolyzed Gardenia Florida Extract plant extract: Hydrolyzed Gardenia Florida Extract is gardenia extract broken into smaller fragments so a water-based formula can carry it evenly.
Maltodextrin film former: Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
Beta-Glucan polysaccharide: Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
Ferulic Acid antioxidant: Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often.
Fullerenes antioxidant: Fullerenes are hollow cage-shaped carbon molecules, C60 the best known of them. They are used as an antioxidant and are notably more stable than the vitamin antioxidants.

How it works

This two-piece treatment centers its essence step on hydroxypinacolone retinoate, retinol and bakuchiol, the same retinoid combination VT uses across its Reti-A line, alongside niacinamide for tone support. Centella asiatica extract and its purified compounds, madecassoside, madecassic acid and asiatic acid, run through the essence to keep the retinoid work calm. The gel sheets are cool and springy against skin, staying in place through the wear time rather than sliding off. The two-step format layers a concentrated essence under a broader hydrogel sheet built around panthenol, beta-glucan and shea butter, left on for ten to twenty minutes before peeling away. This is an occasional-use treatment step rather than an everyday one, given the combined retinoids in the essence.

How to use

Use it in the evening only, after toner, and not in the morning.
Massage the essence step in, then place the two hydrogel pieces over it.
Wear it for the time on the pack, then press in what it leaves.
Do not use another retinoid or an acid on the same evening.

Worth knowing

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