How it works
The ADLAY NIACIN GRAIN MASK is a 120ml sheet mask, used after toner, in place of your serum step, in the evening. The active it is built around is Niacinamide, named tenth on its own ingredient list. The same list carries Glycyrrhiza Glabra (Licorice) Root Extract, Salix Alba (Willow) Bark Extract and Squalane, 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 FULLY sells in Korea, Niacinamide and all.
Key benefits
- Niacinamide, the active this sheet mask is built around
- Glycyrrhiza Glabra (Licorice) Root Extract and Salix Alba (Willow) Bark Extract on the same list, plant extracts
- Squalane on the same list, an emollient
- Panthenol on the same list, a humectant
- Sodium Hyaluronate and Palmitic Acid further down the same list
- Niacinamide named tenth on the manufacturer list printed on this page
How to use
- Massage over dry or damp skin to lift makeup and sunscreen, then rinse or wipe clean, as a first cleanse or a stand-alone wash.
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.
What else is on the list besides Niacinamide?
Glycyrrhiza Glabra (Licorice) Root Extract, Salix Alba (Willow) Bark Extract and Squalane. 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: Panthenol, Sodium Hyaluronate and Palmitic Acid.

29 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.
- Kaolin absorbent
- Kaolin is white clay, the mildest of the cosmetic clays. It absorbs oil and lifts loose debris from the surface without stripping, which is why it is the clay used on drier skin.
- 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.
- Glyceryl Stearates 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.
- Palmitic Acid fatty acid
- Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
- 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.
- Niacinamide (1%) 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.
- Sodium Carboxymethyl Starch thickener
- Modified starch that swells strongly in water. It thickens and gives a formula a soft, cushioned body.
- 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.
- 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.
17 more explained
- Magnesium Aluminum Silicate thickener
- A refined clay mineral used to thicken water and hold powders and pigments suspended so a formula does not separate.
- Methyl Trimethicone silicone
- Methyl Trimethicone is a light, volatile silicone chosen for a notably dry finish. It thins a formula and disperses powders evenly.
- 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.
- 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.
- Sodium Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is a pre-neutralised polymer thickener that gels on contact with water and stabilises an emulsion without heat.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Glycyrrhiza Glabra (Licorice) Root Extract plant extract
- Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
- Salix Alba (Willow) Bark Extract plant extract
- Willow Bark Extract carries salicin, the plant compound salicylic acid is related to. The two are not interchangeable: willow bark is a mild clarifying extract, not a BHA exfoliant at the levels used in cosmetics.
