Round Lab Soybean Panthenol Mask 10ct
Is the Soybean Panthenol Mask 10ct on this page the Korean-market formula?
Yes. It is the release Round Lab makes for sale inside Korea. The same product name can carry a different ingredient list or a different size in an export version, and we list only the Korean one. Round Lab is one of the brands where we have documented a Korean formula and a US formula that genuinely differ.
Where does the Soybean Panthenol Mask 10ct sit in a routine?
It occupies the mask step. Build the routine around the step you are replacing rather than the brand you recognise: a cleanser, a hydrating toner, one serum and one moisturizer is a complete routine, and four products chosen carefully tell you more about your skin than ten bought at once.
What size is the Soybean Panthenol Mask 10ct?
10 ea. That is the size Round Lab sells in Korea for this product; it is the same size sold in Korea: we do not substitute an export format or a US size for the Korean one.
How does buying the Soybean Panthenol Mask 10ct here compare with a US retailer?
The unit sold here is the unit built for the Korean market, with the Korean barcode and batch code intact on the box. A US listing carrying the same product name may be the export version and rarely tells you which one it is sending.

39 of 40 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.
- 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.
- 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.
- Glycine Max (Soybean) Seed Extract (1,176ppm) plant extract
- Soybean Seed Extract carries isoflavones, plant sterols and soy proteins. It is used as a conditioning antioxidant extract.
- Panthenol (510ppm) 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.
- 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.
- Cholesterol barrier lipid
- Cholesterol is the third of the three lipids the outer layer of skin is built from, with ceramides and fatty acids. Formulas that carry all three are following the ratio skin itself holds.
- Brassica Campestris (Rapeseed) Sterols emollient
- Phytosterols are plant sterols, structurally close to the cholesterol in skin's own lipid layer. They soften skin and help the oil phase of a formula hold together.
- Oleic Acid fatty acid
- Oleic Acid is the main fatty acid in olive and many nut oils. It is a rich emollient that softens skin and can feel heavy on skin prone to congestion.
- 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.
- Ceramide AP barrier lipid
- Ceramide AP is a second cosmetic ceramide, distinguished by an extra hydroxyl group. Formulas that name several ceramides are copying the mix skin actually holds rather than relying on one.
27 more explained
- 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.
- 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.
- Hydroxyethyl Acrylate/Sodium Acryloyldimethyl Taurate Copolymer thickener
- This is the thickener behind most gel-cream textures. It builds a soft, bouncy gel that collapses to a light fluid as it is rubbed in.
- Polyurethane-15 film former
- Polyurethane-15 is a flexible film-forming polymer. It holds a formula in place as a stretchy film, which is why it appears in long-wear and peel-off products.
- 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.
- 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.
- Glyceryl Stearate SE emulsifier
- Glyceryl Stearate SE is the self-emulsifying grade, supplied with a little soap already built in so it can hold an emulsion with less help. It thickens and softens like the plain form.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- 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.
- 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.
- Sodium Surfactin surfactant
- A biosurfactant produced by Bacillus fermentation. It lowers surface tension at very low concentrations, so a formula needs very little of it.
- Phytosphingosine barrier lipid
- Phytosphingosine is the backbone every ceramide is built on, and skin uses it in its own lipid layer. In a formula it works with ceramides and cholesterol and also keeps the product stable against microbes.
- Tetraacetylphytosphingosine barrier lipid
- A protected form of phytosphingosine, one of the sphingoid bases that ceramides are built from. The acetyl groups are what keep it stable in a formula.
- 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.
- 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.

How it works
Most sheet masks are hydrating, and this one is doing barrier work instead, which shows in what is on the list. Ceramide NP, ceramide AP, cholesterol, oleic acid, stearic acid and rapeseed sterols are the lipid side, with soybean seed extract and panthenol, the two ingredients the line is named for, alongside them. It goes on after cleansing and toner, replacing the serum step for that evening, and what is left gets patted in. Skin that is stinging at products it used to tolerate is the case for a mask like this over a hydrating one. Use it two or three times a week through a bad stretch, then keep it as an occasional step.
How to use
- Use the Soybean Panthenol Mask after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Patch test on the inner arm before first use on the face, especially if trying this brand or formula for the first time.
- Store away from direct sunlight and heat so the formula and any actives inside stay stable through its shelf life.
