Where does this toner go in my routine?

Straight after cleansing, morning and evening, while the face is still damp. Anything thinner than a toner goes on before it, and anything richer goes on after. If you are adding it to a routine you already like, give it a week on its own first, so what you see is the Hydrolyzed Collagen and not three changes at once.

Does this toner contain fragrance?

Yes. The ingredient list names Fragrance. It sits on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this toner is not the one.

What else is on the list besides Hydrolyzed Collagen?

Niacinamide, Adenosine and Alteromonas Ferment Extract. The order they are printed in on this toner's panel is the order on the box, so you can see where Hydrolyzed Collagen sits relative to them. Further down the same panel: Ceramide NP, Soluble Collagen and Elastin.

How it works

The Revitalizing Collagen Toner is a 120ml toner, used straight after cleansing, morning and evening, while the face is still damp. The protein it is built around is Hydrolyzed Collagen, named seventh on its own ingredient list. The same list carries Niacinamide, Adenosine and Alteromonas Ferment Extract, so the protein is not the only thing on it worth naming. How much of the Hydrolyzed Collagen stays on the skin, and for how long, is decided by the toner format rather than by the list alone. Centellian24 sells this Hydrolyzed Collagen toner in Korea, and this is that version.

Key actives

5Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. The panel names it fifth on this toner's list, beside Hydrolyzed Collagen.

All products with Niacinamide

7Hydrolyzed Collagenprotein

Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film. It is the entry this toner is named after, and the list carries it.

All products with Hydrolyzed Collagen

12Alteromonas Ferment Extractferment

A ferment of a marine bacterium, extracted after culture. It supplies an exopolysaccharide that holds water and leaves a smooth film, which is what it is used for. It is named twelfth on this toner's list, alongside Hydrolyzed Collagen.

19Adenosineactive

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. It is named nineteenth on this toner's list, alongside Hydrolyzed Collagen.

All products with Adenosine

24Ceramide NPbarrier 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. The panel names it twenty-fourth on this toner's list, beside Hydrolyzed Collagen.

1 of 2

30 of 32 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.
Methylpropanediol humectant: Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
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.
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.
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.
Hydrolyzed Collagen (10,000ppm) protein: Hydrolyzed Collagen is collagen broken into fragments small enough to dissolve in water. It cannot become collagen in skin; what it does is hold water at the surface and leave a smooth, conditioned film.
Arctium Lappa Root Extract plant extract: Burdock root extract, the ueong eaten in Korea. It carries inulin and polyphenols and is used as a conditioning extract.
Phellinus Linteus Extract plant extract: Sanghuang, a hard bracket mushroom used in Korean and Chinese herbal tradition. Its extract carries water-holding polysaccharides.
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.
Ficus Carica Fruit Extract plant extract: Fig Fruit Extract carries fruit sugars, mild acids and a protein-digesting enzyme. It is used as a hydrating extract with a light smoothing effect.
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.

18 more explained

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.
Octyldodeceth-16 emulsifier: An ethoxylated branched fatty alcohol. It emulsifies and also gives a formula a soft, cushioned slip.
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.
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.
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 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.
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.
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.
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.
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.
Fructan humectant: Fructan is a chain of fructose units, usually from chicory. It holds water at the surface and forms a light, conditioning film.
Collagen Amino Acids (1ppm) amino acid: Collagen Amino Acids are collagen broken all the way down to its individual amino acids. At that size they act as humectants, the same job skin's own amino acids do.
Elastin protein: Elastin is the stretchy structural protein that sits alongside collagen in the dermis. It cannot enter skin from the outside, so in a formula it is a water-holding, film-forming protein.
Hyaluronic Acid humectant: Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
Fragrance fragrance: Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
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.
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.

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

Topical collagen is a very large molecule that's too big to absorb into the skin.
Michelle Henry, MDDermatologist, Cosmopolitan
Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
