How it works
The Panthenol Barrier Ampoule is a 30ml ampoule, used after toner and before moisturizer, morning and evening. The humectant it is built around is Panthenol, named third on its own ingredient list. The same list carries Niacinamide, Adenosine and Beta-Glucan, so the humectant is not the only thing on it worth naming. How much of the Panthenol stays on the skin, and for how long, is decided by the ampoule format rather than by the list alone. COSNORI sells this Panthenol ampoule in Korea, and this is that version.
Key benefits
- Panthenol, the humectant this ampoule is built around
- Niacinamide and Adenosine on the same list, actives
- Beta-Glucan on the same list, a polysaccharide
- Terminalia Ferdinandiana Fruit Extract on the same list, a plant extract
- Laminaria Japonica Extract and Eclipta Prostrata Extract further down the same list
- Raffinose and Sodium Hyaluronate further down the same list
How to use
- Apply a few drops to clean skin after toner, morning or night as directed on the pack, and follow with moisturizer to seal it in. Ampoules are typically used as a concentrated course rather than an everyday staple.
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule goes on before it, and anything richer goes on after. 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 Panthenol and not three changes at once.
What else is on the list besides Panthenol?
Niacinamide, Adenosine and Beta-Glucan. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Panthenol sits relative to them. Further down the same panel: Terminalia Ferdinandiana Fruit Extract, Laminaria Japonica Extract and Eclipta Prostrata Extract.

Ingredient list read from inkeedecoder.com on 10 September 2026.
23 of 23 explained
- Terminalia Ferdinandiana Fruit Extract plant extract
- Kakadu plum fruit extract, the highest natural source of vitamin C known. It is used as a plant antioxidant.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- Methylpropanediol humectant
- Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
- 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.
- 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.
- 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.
- Laminaria Japonica Extract plant extract
- Laminaria Japonica is kombu kelp. Its extract carries alginates, minerals and iodine, and it is used as a hydrating, mineral-rich ingredient.
- Eclipta Prostrata Leaf Extract plant extract
- Eclipta Prostrata is false daisy, long used in Ayurvedic and East Asian practice. Its extract is used as a conditioning plant extract, most often in scalp and hair formulas.
- Artemisia Vulgaris Oil fragrance component
- Mugwort essential oil. It scents a formula as well as conditioning it, and essential oils are the class most likely to bother reactive skin.
- 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.
11 more explained
- Octyldodeceth-16 emulsifier
- An ethoxylated branched fatty alcohol. It emulsifies and also gives a formula a soft, cushioned slip.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Raffinose sugar
- Raffinose is a three-unit plant sugar found in beans and beetroot. It holds water in the outer layer of skin and helps a formula stay comfortable as it dries down.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- 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.
- 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.
- Fructooligosaccharides humectant
- Fructooligosaccharides are short fructose chains used as humectants and as food for the skin's own resident microbes.
- 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.
- 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.
- Hydrolyzed Hyaluronic Acid humectant
- Hydrolyzed Hyaluronic Acid is hyaluronic acid cut into much shorter fragments. The smaller the fragment, the further into the outer layer it can settle, which is why serums stack several sizes together instead of using one.
- 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.
