Is the Hyalu-Teca Glass Skin Milk 210ml sold here the Korean-market formula, not a US reformulation?

Yes. This listing is the release SKIN1004 sells for use inside Korea, the same formula Korean shoppers buy off the shelf there. A product with the same name can carry a different ingredient list or a different size in an export version, and we source and list only the Korean one, with that market's barcode and batch code intact on the unit that ships to you.

What is Niacinamide doing in this formula?

Niacinamide is the first ingredient of real substance on this product's own ingredient list, which puts it at the front of what the formula is built around rather than a trace addition. The rest of the list supports the texture and feel around it, in the concentration order the manufacturer itself declares.

Where does the Hyalu-Teca Glass Skin Milk 210ml sit in a routine?

It occupies the treatment step. Applied to clean skin at the point in the routine the product is meant for. Build a routine around the step you are replacing rather than the brand you recognize, since a handful of well-chosen steps tells you more about your skin than a shelf of unrelated products.

What size does the Hyalu-Teca Glass Skin Milk 210ml ship in?

It ships at 210ml, the size SKIN1004 sells this product at inside Korea. We do not substitute an export format or a US-only size for the Korean one, so what you receive matches what a shopper buys for it in Seoul.

How can I check that my Hyalu-Teca Glass Skin Milk 210ml is genuine?

Your unit ships with its Korean-market barcode and batch code intact.

How it works

This treatment opens its ingredient list with Niacinamide, ahead of the rest of the formula, which is the clearest sign of what it is built around. Sodium Hyaluronate follows further down the list, part of the supporting cast rather than the headline. Centella Asiatica Extract follows further down the list, part of the supporting cast rather than the headline. That order is why SKIN1004 positions Hyalu-Teca Glass Skin Milk 210ml as a treatment rather than a general moisturizer or cleanser: the concentration and format are built for the treatment step, not for every step in a routine. It belongs in the treatment step, applied to clean skin at the point in the routine the product is meant for.

1 of 3

69 of 69 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.
Diphenylsiloxy Phenyl Trimethicone silicone: Diphenylsiloxy Phenyl Trimethicone is a high-shine silicone used where a formula needs gloss without stickiness.
Pentaerythrityl Tetraethylhexanoate emollient: Pentaerythrityl Tetraethylhexanoate is a light ester emollient that gives a dry, silky finish and disperses pigment evenly.
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.
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.
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.
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.
Sodium Stearoyl Glutamate emulsifier: Sodium Stearoyl Glutamate is an amino-acid-derived emulsifier. It holds oil and water together and is mild enough for formulas built for reactive 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.
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.

57 more explained

Cetearyl Alcohol fatty alcohol: Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener: This is the thickener behind most gel-cream textures. It builds a soft, bouncy gel that collapses to a light fluid as it is rubbed in.
Chondrus Crispus 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.
Cetearyl Olivate emulsifier: Cetearyl Olivate is the water-loving half of the olive-derived emulsifier pair. With sorbitan olivate it builds emulsions whose lipid profile is close to skin's own.
Sorbitan Olivate emulsifier: Sorbitan Olivate is an olive-derived emulsifier, the oil-loving half of the pair sold as Olivem. It holds oil into water and leaves a light, non-waxy feel.
Saccharum Officinarum (Sugarcane) Extract plant extract: Sugarcane Extract carries natural glycolic acid and sugars. In cosmetics it is used as a humectant; the acid content is far too low to work as an exfoliant.
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.
Acrylates/C10-30 Alkyl Acrylate Crosspolymer thickener: This is a carbomer relative with fatty side chains, so it thickens and stabilises an emulsion at the same time. It gives a light gel-cream body rather than a heavy one.
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.
Microcrystalline Cellulose absorbent: Microcrystalline Cellulose is purified cellulose ground fine. It thickens, holds powders in suspension and gives a soft, matte feel.
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.
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.
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.
Sphingomonas Ferment Extract ferment: Sphingomonas Ferment Extract is the liquid left after Sphingomonas bacteria have fermented a sugar substrate. It carries water-holding polysaccharides and is used as a conditioning ferment.
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.
Sodium Dilauramidoglutamide Lysine barrier lipid: An amino-acid-based lipid built from glutamic acid and lysine. It behaves like the lipids between skin cells and forms a liquid-crystal structure that holds water in.
Polysorbate 60 emulsifier: Polysorbate 60 is a water-loving emulsifier used with a fatty co-emulsifier to build stable lotions and creams.
Sorbitan Isostearate emulsifier: Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
C12-13 Alketh-9 emulsifier: C12-13 Alketh-9 is a solubiliser used to disperse oil-soluble ingredients evenly in a watery formula.
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.
Musa Sapientum (Banana) Flower Extract plant extract: Banana flower extract, an ingredient of South and Southeast Asian cooking. It carries flavonoids and sugars and is used as a conditioning extract.
Rosa Damascena Flower Water plant extract: Rosa Damascena Flower Water is the water left from distilling rose petals. It is used in place of plain water as a base and carries the scent and trace compounds of the distillation.
Pyrus Communis (Pear) Fruit Extract plant extract: Pear Fruit Extract carries fruit sugars and mild fruit acids. It is used as a hydrating extract with a very light smoothing effect on the surface.
Prunus Domestica Fruit Extract plant extract: European plum fruit extract, carrying sorbitol, sugars and polyphenols. It is used as a conditioning, water-holding extract.
Ethoxydiglycol solvent: Ethoxydiglycol is a solvent that keeps stubborn actives in solution, most often vitamin C or an acid, and helps them spread evenly instead of settling out.
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.
Cucumis Melo (Melon) Fruit Extract plant extract: Melon Fruit Extract carries fruit sugars and a natural antioxidant enzyme system. It is used as a light hydrating extract.
Hedera Helix (Ivy) Leaf/Stem Extract plant extract: Ivy Leaf and Stem Extract carries saponins, plant compounds that foam slightly in water. It is used in body and eye formulas for the look of puffiness.
Octyldodecanol emollient: Octyldodecanol is a branched fatty alcohol used as an emollient and as a solvent for pigments and mineral powders. It thickens slightly and leaves a soft finish.
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.
Glycolipids barrier lipid: Glycolipids are lipids joined to a sugar. In a formula they work partly as barrier lipids and partly as mild emulsifiers, holding oil and water together.
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.
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.
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.
Glutamic Acid amino acid: Glutamic Acid is an amino acid used as a humectant and a mild pH adjuster. It is one of the components of skin's natural moisturising factor.
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.
Phytosphingosine barrier lipid: Phytosphingosine is the backbone every ceramide is built on, and skin uses it in its own lipid layer. In a formula it works with ceramides and cholesterol and also keeps the product stable against microbes.
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.
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.
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.
Squalane emollient: Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.
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.
Hydrolyzed Soy Protein protein: Hydrolyzed Soy Protein is soy protein cut into water-soluble fragments. It conditions the surface and holds water, and it is one of the most used plant proteins in cosmetics.
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.
Sorbitan Laurate emulsifier: Sorbitan Laurate is a light emulsifier and solubiliser, used to keep small amounts of oil or fragrance dissolved in a watery formula.
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.
Collagen protein: Collagen is the structural protein that makes up most of the dermis. Applied on top it is far too large to enter skin, so in a formula it works as a humectant and a smoothing film former.
Leuconostoc/Radish Root Ferment Filtrate preservative: This is radish root fermented by Leuconostoc, the culture behind kimchi, then filtered clear. It carries natural antimicrobial peptides, so formulas use it in place of part of a conventional preservative.
Avena Sativa (Oat) Peptide peptide: Avena Sativa Peptide is oat protein cut into short fragments. Plant peptides behave as water-holding, film-forming proteins rather than as the signalling peptides of the numbered families.
Collagen Extract 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.
Hydroxyethylcellulose thickener: Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
Acetyl Dipeptide-1 Cetyl Ester peptide: Acetyl Dipeptide-1 Cetyl Ester is a two-amino-acid peptide with a fatty cetyl tail attached, which lets it sit in the oil phase of a formula rather than only the water phase.
Hexapeptide-2 peptide: Hexapeptide-2 is a six-amino-acid peptide used for the look of even tone rather than of lines, which puts it in the smaller group of peptides aimed at pigment.
Biotin vitamin: Biotin is vitamin B7. In skincare it is a conditioning vitamin, most often in hair and scalp formulas.
Nonapeptide-1 peptide: Nonapeptide-1 is a nine-amino-acid peptide used for the look of uneven tone rather than for firmness, which makes it unusual among cosmetic peptides.
Palmitoyl Pentapeptide-4 peptide: Palmitoyl Pentapeptide-4 is the five-amino-acid peptide originally sold as Matrixyl. It is used for the look of fine lines and is one of the longest-standing cosmetic peptides.
