How it works
An ampoule is the most concentrated step in a Korean routine and it is sold in small sizes for that reason. It goes on in drops rather than in palmfuls, and the surface feels slightly denser afterwards than it does after an essence. Nourishing in cosmetic terms means a heavier finish and a softer feel, and that comes from texture rather than from any one ingredient. That is the difference from an essence, which is a thin everyday layer rather than a short concentrated course. The result you can judge yourself is whether your skin feels soft and cushioned instead of tight by the evening.
Key benefits
- Soybean Panthenol Ampoule 50ml is Round Lab's serum, sourced for the Korean market rather than reformulated for US shelves.
- Carries Glycine Max (Soybean) Seed Extract, which is the fermented soybean extract behind Round Lab's Soybean line, chosen for its skin-conditioning fatty acid profile.
- Carries Panthenol, which is provitamin B5, a humectant that helps a formula feel less tight after it dries down.
- Carries Ceramide AP, which is a lipid that mimics the skin's own barrier-building blocks, a staple of Korean barrier-support formulas.
- Ships with the Korean-market barcode and batch code intact, the same box sold on Korean shelves rather than a US repack.
- Suited to shoppers targeting dehydration and a compromised moisture barrier.
Inside the formula
Inside the formula
What is Soybean Panthenol Ampoule 50ml?
It is a concentrated ampoule from Round Lab, made for dry skin that wants a richer finish, and anyone whose usual moisturiser stops feeling like enough in winter. It goes on after your toner or essence and before your cream, which is the thin to thick order. The result you can judge yourself is whether your skin feels soft and cushioned instead of tight by the evening.
Where does Soybean Panthenol Ampoule 50ml go in my routine?
It goes on after your toner or essence and before your cream, which is the thin to thick order. In practice: Press two or three drops over the areas that need it after your toner, then seal with your usual moisturiser. Applying it out of that order is the usual reason a step seems to do nothing.
Is Soybean Panthenol Ampoule 50ml right for my skin type?
It is aimed at dry skin that wants a richer finish, and anyone whose usual moisturiser stops feeling like enough in winter. The skin types we would put first are dry skin, very dry skin and normal skin. Richness is a matter of season and area rather than skin type, so many people use a step like this in winter and something lighter in summer.
Do I still need a moisturiser on top of an ampoule?
Yes. An ampoule is a concentrated step, not an occlusive one, so it has nothing to hold the water it leaves behind. Follow it with your usual cream or emulsion, and choose a richer one in winter. Skipping the cream is the most common reason a good ampoule leaves skin feeling tight an hour later.
Is this Soybean Panthenol Ampoule 50ml the authentic Korean-market formula?
Yes. We stock the Round Lab Korean-market formula rather than a version reformulated for US shelves. The bottle you open is the 50ml one sold on Korean shelves, with Korean-primary packaging and an intact barcode you can check yourself.

32 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.
- 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.
- 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.
- Glycine Max (Soybean) Seed Extract(10,000ppm) plant extract
- Soybean Seed Extract carries isoflavones, plant sterols and soy proteins. It is used as a conditioning antioxidant extract.
- Panthenol(2,550ppm) 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 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.
- 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.
- 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.
- 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.
- Ulmus Davidiana Root Extract plant extract
- Ulmus Davidiana is Japanese elm, whose inner bark yields a naturally slippery mucilage. Korean formulas use the root extract for that cushioned feel and for the look of reactive skin.
- Amaranthus Caudatus Seed Extract plant extract
- Amaranth seed extract, carrying squalene, sterols and peptides. It is used as a conditioning extract.
20 more explained
- 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.
- 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.
- Pentaerythrityl Tetraethylhexanoate emollient
- Pentaerythrityl Tetraethylhexanoate is a light ester emollient that gives a dry, silky finish and disperses pigment evenly.
- Hexyldecyl Ethylhexanoate emollient
- A branched ester emollient. It spreads quickly, feels dry rather than rich, and is used to soften the heaviness of thicker oils in a blend.
- 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.
- 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.
- 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.
- 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.
- 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.
- Polyglyceryl-10 Stearate emulsifier
- Polyglyceryl-10 Stearate is a mild sugar-derived emulsifier that holds oil into water and thickens slightly.
- 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.
- Glycosphingolipids barrier lipid
- Glycosphingolipids are ceramide-family lipids carrying a sugar group. They belong to the same lipid structure between skin cells and are used to make a formula feel more conditioning.
- 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 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.
- 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.
- 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.
- 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.
- 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.

How to use
- Use it after your toner or essence, when the skin is still slightly damp.
- Take two or three drops, press them over the areas that need the work and then over the rest of the face.
- Seal it with your moisturiser, since an ampoule on its own leaves the surface a little tacky.
- Do not use it in place of your moisturiser, and do not start with a full pipette on skin that has not had it before.
Worth knowing
- Patch test on a small area first if your skin reacts easily to new products.
- Use less than you think on oily or congestion prone areas, since a rich texture can feel heavy there.
