Where does this sheet mask go in my routine?

After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. 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 Niacinamide and not three changes at once.

Is this the Korean-market sheet mask or a US version?

The Korean-market one, Niacinamide and all. We match this sheet mask to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.

Does this sheet mask contain fragrance?

Yes. The ingredient list names Citral, Citronellol, Geraniol and Limonene. They sit 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 sheet mask is not the one.

What else is on the list besides Niacinamide?

Cyanocobalamin, Tocopherol and Ascorbic Acid. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Avena Sativa (Oat) Kernel Extract, Calendula Officinalis Flower Extract and Stellaria Media (Chickweed) Extract.

How it works

The Super Knights Multi-vitamin Mask is a 75ml sheet mask, used after toner, in place of your serum step, in the evening. The active it is built around is Niacinamide, named twenty-first on its own ingredient list. The same list carries Cyanocobalamin, Tocopherol and Ascorbic Acid, so the active is not the only thing on it worth naming. How much of the Niacinamide stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. This is the Original Korean Formula, the sheet mask Belif sells in Korea, Niacinamide and all.

Key benefits

Niacinamide, the active this sheet mask is built around
Cyanocobalamin on the same list, a vitamin
Tocopherol and Ascorbic Acid on the same list, antioxidants
Avena Sativa (Oat) Kernel Extract on the same list, a plant extract
Calendula Officinalis Flower Extract and Stellaria Media (Chickweed) Extract further down the same list
Rosa Damascena Flower Extract and Viola Tricolor Extract further down the same list

Key actives

21Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this sheet mask's own ingredient list it is named twenty-first.

22Tocopherolantioxidant

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. The panel names it twenty-second on this sheet mask's list, beside Niacinamide.

23Avena Sativa (Oat) Kernel Extractplant extract

Oat Kernel Extract carries beta-glucan and avenanthramides, and it is one of the most reliably tolerated ingredients in skincare. It is used for the look of reddened, itchy-feeling skin. It is named twenty-third on this sheet mask's list, alongside Niacinamide.

34Ascorbic Acidantioxidant

Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone. It is named thirty-fourth on this sheet mask's list, alongside Niacinamide.

35Cyanocobalaminvitamin

Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin. It is named thirty-fifth on this sheet mask's list, alongside Niacinamide.

How to use

Apply to clean skin, leave on for the time stated on the pack, then remove and pat in whatever essence remains without rinsing.

1 of 2

44 of 52 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.
Helianthus Annuus (Sunflower) Seed Oil emollient: Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
Dicaprylyl Carbonate emollient: Dicaprylyl Carbonate is a light, fast-spreading emollient with a notably dry finish. It is chosen where a formula has to spread thin without leaving a heavy film.
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.
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.
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.
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.
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.
Polyglyceryl-3 Methylglucose Distearate emulsifier: Polyglyceryl-3 Methylglucose Distearate is a sugar-derived emulsifier known for a light, non-soapy feel. It builds gel-creams that do not read as rich.
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.
Glyceryl Stearate Citrate emulsifier: Glyceryl Stearate Citrate is a mild, citrate-modified emulsifier. It holds oil and water together and is chosen for formulas aimed at reactive skin.

32 more explained

Stearic Acid fatty acid: Stearic Acid is a saturated fatty acid from plant fats, and one of the three lipid classes skin's own barrier is built from. In a formula it thickens, stabilises the emulsion and can be turned into a soap-style cleanser by adding a base.
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.
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.
Lactobacillus/Soybean Ferment Extract ferment: This is soybean fermented by lactobacillus. The fermentation breaks soy proteins into smaller pieces, which is what makes the extract easier for a formula to carry.
Saccharomyces/Potato Extract Ferment Filtrate ferment: Potato extract fermented with yeast and strained. It supplies sugars and amino acids and is used as a conditioning ferment.
Saccharomyces/Barley Seed Ferment Filtrate ferment: Barley fermented with brewing yeast and strained clear. Fermentation breaks the grain starch and protein into sugars, peptides and B vitamins that hold water.
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.
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.
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.
Avena Sativa (Oat) Kernel Extract* plant extract: Oat Kernel Extract carries beta-glucan and avenanthramides, and it is one of the most reliably tolerated ingredients in skincare. It is used for the look of reddened, itchy-feeling skin.
Calendula Officinalis Flower Extract* plant extract: Marigold flower extract, one of the oldest plant ingredients used for the look of reddened, easily bothered skin. It carries carotenoids and flavonoids.
Stellaria Media (Chickweed) Extract* plant extract: Chickweed extract, a common garden herb used for the look of reddened, easily bothered skin. It carries saponins and mucilage.
Rosa Damascena Flower Extract+ plant extract: Damask rose flower extract, the rose grown for perfume. It carries tannins and flavonoids and is used as a conditioning extract.
Viola Tricolor Extract+ plant extract: Heartsease extract, the wild pansy. It carries mucilage and flavonoids, so it hydrates and is used for the look of reddened skin.
Ascorbic Acid antioxidant: Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.
Cyanocobalamin vitamin: Cyanocobalamin is vitamin B12, and it is a deep pink-red, which is why a formula carrying it often has a colour nobody added on purpose. It is used as a conditioning vitamin.
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.
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.
Glycine Soja (Soybean) Oil emollient: Soybean Oil is a linoleic-rich plant oil used as an emollient. It also carries soy phytosterols and vitamin E.
Sodium Citrate pH adjuster: Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
Elaeis Guineensis (Palm) Oil emollient: Palm Oil is a rich emollient high in palmitic and oleic acids. In skincare it is more often a source material for esters and emulsifiers than an ingredient on its own.
Citric Acid pH adjuster: Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
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.
Citrus Aurantifolia (Lime) Oil** fragrance component: Lime oil, an essential oil pressed from the peel. It scents a formula strongly, and expressed citrus oils can make skin more sensitive to sun.
Pelargonium Graveolens Flower Oil** fragrance component: Pelargonium Graveolens is rose geranium. Its flower oil is an essential oil used to scent a formula, carrying citronellol and geraniol.
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.
Citrus Aurantium Dulcis (Orange) Peel Oil** fragrance component: Sweet Orange Peel Oil is a citrus essential oil carrying limonene. It scents a formula, and limonene is one of the components EU labelling names separately.
Limonene fragrance component: Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.
Citronellol fragrance component: Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
Geraniol fragrance component: Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.
Citral fragrance component: Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.
Linalool fragrance component: Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.

People with dry, flaky skin are more likely to see a benefit from using vitamin E because it enhances moisturization.

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.
