How it works
Vitatinol Serum Mega-Shot Gel Mask Sheet 34g X 5ea is a mask from primera, sold here in its Korean-market packaging rather than a US retail reformulation. It takes an occasional intensive step, in place of a nightly serum. As a mask, its job in a routine is set by its format: a mask is chosen for how it sits on skin and how it moves the routine forward, and primera builds this one for exactly that role. A mask in this format holds an essence against skin for a set wear time, which is what a leave-on step cannot do as efficiently.
Key benefits
- A mask from primera's Korean-market lineup, not the US-reformulated version some retailers carry
- Placed for an occasional intensive step, in place of a nightly serum
- Korean-market barcode and batch code intact on the box
- Suits Dehydrated, Dry skin as a mask
- Part of primera's wider Korean-market lineup, not a version reformulated for US retail
Inside the formula
Inside the formula
Is the Vitatinol Serum Mega-Shot Gel Mask Sheet 34g X 5ea sold here primera's Korean-market formula?
Yes. What ships is primera's release for the Korean market: the formula and packaging sold in Korea, with the Korean-market barcode and batch code intact on the box rather than swapped for an export or US-retail label.
Where does the Vitatinol Serum Mega-Shot Gel Mask Sheet 34g X 5ea go in a routine?
It takes an occasional intensive step, in place of a nightly serum. Use it exactly the way you would any mask at that point in a routine. A mask in this format holds an essence against skin for a set wear time, which is what a leave-on step cannot do as efficiently, which is the reason this step order tends to hold across brands, not only for this one.
Who is the Vitatinol Serum Mega-Shot Gel Mask Sheet 34g X 5ea best suited for?
Dehydrated, Dry, Normal skin types get the most straightforward use from a mask in this format. Patch test first, as with any new product entering a routine, and give it a week or two before judging the fit.
What format is the Vitatinol Serum Mega-Shot Gel Mask Sheet 34g X 5ea, and how does that change how it is used?
It is a mask, and the format sets the routine rules that come with it: Apply to clean skin, leave on for the time stated on the pack, then remove and pat in whatever essence remains without rinsing. primera builds this one to match that format rather than departing from it.
How does buying the Vitatinol Serum Mega-Shot Gel Mask Sheet 34g X 5ea here compare with a US retailer carrying the same name?
A US listing under the same product name can be a reformulated export version and rarely states which one it is selling. What we carry is the Korean-market primera release, identified by its intact Korean barcode and batch code on the box rather than a relabeled export carton, so the unit you get matches what is sold on shelf in Korea.

Ingredient list read from prmrbeauty.com on 30 August 2026.
45 of 46 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Carrageenan thickener
- Carrageenan is a red-seaweed polysaccharide that thickens and forms a moisture-holding film. It gives a formula a slippery, cushioned body.
- Diglycerin humectant
- Diglycerin is two glycerin units joined together. It holds water like glycerin but feels less tacky, so it is used where a formula needs hydration without drag.
- Chondrus crispus extract 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.
- 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.
33 more explained
- 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.
- Ethylhexyl olivate emollient
- An ester built from olive oil fatty acids. It gives the softening feel of a plant oil with a lighter, less greasy finish.
- 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.
- 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.
- 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.
- Polyacrylate-13 thickener
- Polyacrylate-13 is a pre-neutralised thickener that gels instantly and holds an emulsion together, so a formula can be built without heat.
- 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 acrylates copolymer thickener
- An acrylate polymer that thickens water and can hold many times its own weight in it. It gives a gel body without any oil.
- 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.
- Polyglyceryl-4 oleate emulsifier
- Polyglyceryl-4 Oleate is a plant-derived emulsifier used in cleansing oils so they rinse cleanly.
- 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.
- Hydrogenated polyisobutene emollient
- Hydrogenated Polyisobutene is a stabilised synthetic hydrocarbon used in place of mineral oil. It is an emollient that leaves a smooth, cushioned film.
- 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.
- 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.
- Agar thickener
- Agar is a seaweed polysaccharide that sets into a firm gel. It is the gelling agent behind jelly masks and thick sleeping packs.
- 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.
- Polyglyceryl-10 laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- Ethylhexyl palmitate emollient
- Ethylhexyl Palmitate is a palm-derived ester used as a light emollient and a solvent for pigment. It gives a smooth, non-greasy slip.
- Cyamopsis tetragonoloba (guar) gum thickener
- Guar Gum is a seed polysaccharide that thickens and stabilises. It also leaves a conditioning film that makes skin feel smooth.
- Glycine max (soybean) polypeptide protein
- Soy protein cut into shorter polypeptide chains. The smaller chains dissolve in water and are used as a conditioning protein that leaves a smooth film.
- Magnesium ascorbyl phosphate antioxidant
- Magnesium Ascorbyl Phosphate is a stable, water-soluble vitamin C salt. It works at a near-neutral pH, so it suits formulas built for skin that finds pure ascorbic acid stinging.
- 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 isostearate emulsifier
- Sorbitan Isostearate is a mild emulsifier that holds water into oil, the direction a cleansing balm or an oil-based cream needs.
- Retinal active
- Retinal is retinaldehyde, a vitamin A derivative one chemical step closer to retinoic acid than retinol is. It is yellow-orange and unstable in light, so products carrying it are usually opaque.
- 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.
- 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.
- 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.
- 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.
- 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.
- Xanthophylls antioxidant
- Xanthophyll is the yellow carotenoid family lutein belongs to, found in marigold and leafy greens. It is used as a plant antioxidant and tints a formula yellow.
- Retinol active
- Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It can leave skin flaking while it acclimatises.
- Sodium ascorbyl phosphate antioxidant
- Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging.
- 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.
