How it works
The Hyaluronic Acid Aqua Gel Cream is a 100ml gel cream, used as the last skincare step, morning and evening, over serum. The humectant it is built around is Sodium Hyaluronate, named tenth on its own ingredient list. The same list carries Biosaccharide Gum-1, Centella Asiatica Extract and Polygonum Cuspidatum Root Extract, so the humectant is not the only thing on it worth naming. How much of the Sodium Hyaluronate stays on the skin, and for how long, is decided by the gel cream format rather than by the list alone. This is the Original Korean Formula, the gel cream Isntree sells in Korea, Sodium Hyaluronate and all.
Key benefits
- Sodium Hyaluronate, the humectant this gel cream is built around
- Biosaccharide Gum-1 on the same list, a polysaccharide
- Centella Asiatica Extract, Polygonum Cuspidatum Root Extract and Scutellaria Baicalensis Root Extract on the same list, plant extracts
- Camellia Sinensis Leaf Extract and Portulaca Oleracea Extract further down the same list
- Glycyrrhiza Glabra (Licorice) Root Extract and Houttuynia Cordata Extract further down the same list
- Sodium Hyaluronate named tenth on the manufacturer list printed on this page
Inside the formula
Inside the formula
Isntree Hyaluronic Acid Aqua Gel Cream
Where does this gel cream go in my routine?
As the last skincare step, morning and evening, over serum. Anything thinner than a gel cream 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 Sodium Hyaluronate and not three changes at once.
Is this the Korean-market gel cream or a US version?
The Korean-market one, Sodium Hyaluronate and all. We match this gel cream to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Sodium Hyaluronate?
Biosaccharide Gum-1, Centella Asiatica Extract and Polygonum Cuspidatum Root Extract. The order they are printed in on this gel cream's panel is the order on the box, so you can see where Sodium Hyaluronate sits relative to them. Further down the same panel: Scutellaria Baicalensis Root Extract, Camellia Sinensis Leaf Extract and Portulaca Oleracea Extract.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, essential oils, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

19 of 20 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.
- 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.
- 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.
- 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.
- Biosaccharide Gum-1 polysaccharide
- Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel.
- 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.
- Ammonium Acryloyldimethyltaurate/VP Copolymer thickener
- This is a synthetic thickener that gels quickly and holds an emulsion stable across a wide pH range. It gives a light, non-tacky body.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- 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.
- 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.
- Centella Asiatica 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.
- Polygonum Cuspidatum Root Extract plant extract
- Polygonum Cuspidatum is Japanese knotweed, the main commercial source of resveratrol. Its root extract is used as an antioxidant plant extract.
7 more explained
- Scutellaria Baicalensis Root Extract plant extract
- Scutellaria Baicalensis is Chinese skullcap. Its root extract carries baicalin, a well studied plant antioxidant, and it is used for the look of redness.
- Camellia Sinensis Leaf Extract plant extract
- Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
- Portulaca Oleracea 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.
- 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.
- Houttuynia Cordata Extract plant extract
- Houttuynia Cordata is heartleaf, and it is one of the two or three anchor plants of Korean calming skincare. Its extract carries quercitrin and other flavonoids and is used for the look of redness and blemish-prone skin.
- Rosmarinus Officinalis (Rosemary) Leaf Extract plant extract
- Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
- Chamomilla Recutita (Chamomile) Flower Extract plant extract
- Chamomile Flower Extract is one of the oldest ingredients in skincare, carrying bisabolol and chamazulene. It is used for the look of redness in formulas for reactive skin.

How to use
- Use the Hyaluronic Acid Aqua Gel Cream as the last skincare step, morning and evening, over serum.
- A generous fingertip for the whole face. It spreads further than a cream, so start with less than you think.
- Serum first, this second. In the morning it is the layer sunscreen goes over, so give it a minute to settle first.
- Twice a day, every day. Do not layer it under a heavier cream to get more out of it; two lids in one routine only slow the first one down.
Worth knowing
- Patch test on the inner arm before a first full-face application if skin tends to react easily.
- Store away from direct sunlight and high heat to keep the texture and scent stable over time.
- Introduce one new active at a time when adding this into an existing routine.
