What does Niacinamide do in this sheet mask?

Niacinamide sits within the first ten ingredients, the tone-evening, barrier-supporting active Korean formulas lean on most often, and its early position here means it is not a token dose.

Is Adenosine also in this formula?

Adenosine sits further down the ingredient list. It is a wrinkle-care ingredient in Korea, included here for fine-line support rather than as a filler. It sits alongside Niacinamide on MEDIHEAL's ingredient list for this product.

How is this sheet mask used in a routine?

Unfold the sheet and smooth it onto a cleansed face, adjusting it around the eyes, nose and mouth. Leave it on for 15 to 20 minutes, then remove and pat any remaining essence into the skin rather than rinsing it off. It works as an occasional, concentrated step layered over a completed routine, not a daily one.

Who is this sheet mask suited for?

Normal skin, Dry or dehydrated skin are the best fit for this sheet mask. Patch test on the inner arm before first full use, as with any new skincare product.

How it works

The panel on this sheet mask names four forms of collagen rather than one: Collagen, Hydrolyzed Collagen, Soluble Collagen, Collagen Extract. 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. On this panel it sits alongside Niacinamide, Chondrus Crispus Powder and Potassium Chloride. 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.

Key actives

4Niacinamide

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.

All products with Niacinamide

9Chondrus Crispus Powder

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.

All products with Chondrus Crispus Extract

14Potassium Chloride

Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.

All products with Potassium Chloride

18Collagen

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.

All products with Collagen

40Hydrolyzed Collagen

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.

All products with Hydrolyzed Collagen

45Soluble Collagen

Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.

All products with Soluble Collagen

48Collagen Extract

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.

47 of 49 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.
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.
Cetyl Ethylhexanoate emollient: Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
Caprylic/Capric Triglyceride emollient: Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
Ceratonia Siliqua (Carob) Gum thickener: Carob Gum is a seed polysaccharide from the carob tree. It thickens a formula and gives a soft, cushioned body.
Chondrus Crispus Powder 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.
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.
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.
Butyrospermum Parkii (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.
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.

Potassium Chloride mineral: Potassium Chloride is a mineral salt used to bring a formula closer to the salt balance of skin, most often as part of a sea-water or mineral-water blend.
Jojoba Esters emollient: Jojoba Esters are jojoba wax rebuilt into a softer, meltable form. They condition skin and give body to balms without the heaviness of a butter.
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.
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.
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.
Stearyl Alcohol fatty alcohol: Stearyl Alcohol is a solid fatty alcohol used to thicken and stabilise creams. Like the other fatty alcohols it is an emollient, not a solvent.
Cetyl Alcohol fatty alcohol: Cetyl Alcohol is a waxy fatty alcohol from coconut or palm, unrelated to drying ethanol. It thickens creams, stabilises the emulsion and leaves skin feeling softer.
Sorbitan Sesquioleate emulsifier: Sorbitan Sesquioleate is a water-in-oil emulsifier and pigment disperser. Cleansing oils use it so water can be worked into the oil at the rinse.
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.
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.
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.
Helianthus Annuus (Sunflower) Seed Wax occlusive: Sunflower seed wax, used to firm up sticks and balms. It is softer than carnauba and gives a less brittle set.
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.
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.
Rosmarinus Officinalis (Rosemary) Leaf Oil fragrance component: Rosemary Leaf Oil is an essential oil carrying camphor and cineole. It scents a formula and is a stronger aromatic than most.
Trideceth-6 emulsifier: Trideceth-6 is a solubiliser used to dissolve fragrance and oil-soluble ingredients into a watery formula so it stays clear.
C11-13 Isoalkane emollient: A very light branched hydrocarbon. It spreads a formula quickly, then most of it evaporates rather than staying on skin.
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.
Polyglycerin-3 humectant: Polyglycerin-3 is a short chain of glycerin units used as a gentler, less sticky humectant. It also helps oils and water stay blended.
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.
Lavandula Angustifolia (Lavender) Oil fragrance component: Lavender Oil is an essential oil carrying linalool and linalyl acetate. It scents a formula, and linalool is one of the fragrance components EU labelling requires to be named separately.
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.
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.
Glutathione antioxidant: Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it.
Hydrolyzed Collagen 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.
Lycium Chinense Fruit Extract plant extract: Goji berry fruit extract, the gugija brewed as tea in Korea. It carries carotenoids and polysaccharides and is used as an antioxidant conditioning extract.
Punica Granatum Fruit Extract plant extract: Pomegranate fruit extract, carrying ellagic acid and punicalagins. It is used as a plant antioxidant.
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.
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.
Soluble Collagen protein: Soluble Collagen is collagen kept in its intact triple-helix form and dissolved rather than cut up. It sits on the surface as a water-holding film.
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.
Mannose sugar: Mannose is a simple sugar closely related to glucose. It is used as a humectant and as a building block in the polysaccharide blends that hold water on the surface.
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.
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.
