What is the IUNIK Propolis Vitamin Sleeping Mask 60ml for?

It is a sleeping mask from IUNIK's Korean-market lineup, an overnight mask, left on rather than rinsed, the last step of a PM routine. It ships as the same formula sold in Korea rather than a US-shelf reformulation, so the ingredient list on the box matches what Korean shoppers buy. Its own ingredient list carries Propolis Extract and Centella Asiatica Leaf Water, confirmed on the row rather than assumed from the name.

When should I use this sleeping mask in my routine?

PM, as the last step of the night routine, applied in a slightly thicker layer than a regular cream and left on overnight. Keep the same order every time you use it so you can tell what is actually working for your skin.

Can I use this alongside the rest of my existing routine?

Yes. This sleeping mask is built to sit at one step in a routine rather than replace every other product in it, so it layers with the rest of what you already use. Introduce it on its own for the first few uses before adding anything new alongside it, so you can tell what any reaction traces back to.

Is this the same formula sold in Korea, or a US version?

The ingredient list on the box is the same one Korean shoppers see on the shelf.

How long does a 60 ml typically last with regular use?

That depends on how much is used per application and how many steps sit around it in your routine, since a sleeping mask used once or twice daily is used differently from one used weekly.

How it works

A sleeping mask is left on overnight rather than rinsed off, giving an ingredient like propolis more contact time with skin than a rinse-off mask allows.

32 of 34 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.
Propolis Extract plant extract: Propolis is the resin bees collect from tree buds and use to seal the hive. It is rich in flavonoids, carries a warm amber colour and scent, and is used for the look of dull, stressed skin. It is a bee product, so it is worth knowing about if you react to those.
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.
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.
Hippophae Rhamnoides (Sea Buckthorn) Fruit Extract plant extract: Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract.
Centella Asiatica Leaf Water plant extract: Centella Asiatica Leaf Water is the distilled water of the centella leaf, used in place of plain water as a formula base. It is far more dilute than the extract, so it sets the base rather than supplying the actives.
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.
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.
Cyclopentasiloxane silicone: Cyclopentasiloxane is a volatile silicone: it spreads a formula thin and smooth then evaporates, leaving no residue. It is the silicone behind a dry, powdery primer finish.
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.
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.
Cyclohexasiloxane silicone: Cyclohexasiloxane is a volatile silicone used for a light, fast-spreading feel that leaves nothing behind.

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.
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.
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.
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.
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.
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.
Cetearyl Glucoside emulsifier: Cetearyl Glucoside is a sugar-derived emulsifier used to hold oil and water together in creams with a light finish.
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.
Centella Asiatica (Gotu Kola) 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.
Portulaca Oleracea (Green Purslane) Extract plant extract: Portulaca Oleracea is purslane. Its extract is unusually high in omega-3 fatty acids and antioxidants for a plant, and Korean formulas use it for the look of reddened, reactive skin.
Allantoin active: Allantoin is a comfrey-derived compound used to condition skin and soften the outer layer so it feels smoother. It is one of the standard additions to a formula built for easily irritated skin.
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.
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.
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.
Aloe Barbadensis (Aloe Vera) Leaf Extract plant extract: Aloe Leaf Extract is mostly water with polysaccharides, amino acids and mild plant acids. It hydrates and leaves a light, cooling film, which is why it is the default after-sun ingredient.
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.
Aspalathus Linearis (Rooibos) Extract plant extract: Rooibos extract, from the South African red bush. It carries aspalathin and other flavonoids and no caffeine, and it is used as a plant antioxidant.
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.
Perilla Frutescens Leaf Extract plant extract: Kkaennip, the perilla leaf eaten across Korea. Its extract carries rosmarinic acid and is used as an antioxidant conditioning extract.
