How it works
The Hyaluronic Acid Low-pH Cleansing Foam is a 150ml foam cleanser, used as your first step, morning and evening, on a face already wet with lukewarm water. The humectant it is built around is Sodium Hyaluronate, named ninth on its own ingredient list. The same list carries Dipotassium Glycyrrhizate, Allantoin and Ceramide NP, 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 foam cleanser format rather than by the list alone. This is the Original Korean Formula, the foam cleanser Isntree sells in Korea, Sodium Hyaluronate and all.

Isntree Hyaluronic Acid Low-pH Cleansing Foam
Where does this foam cleanser go in my routine?
As your first step, morning and evening, on a face already wet with lukewarm water. Nothing goes under it: this foam cleanser is the step everything else in the routine lands on top of. 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 foam cleanser or a US version?
The Korean-market one, Sodium Hyaluronate and all. We match this foam cleanser 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?
Dipotassium Glycyrrhizate, Allantoin and Ceramide NP. The order they are printed in on this foam cleanser's panel is the order on the box, so you can see where Sodium Hyaluronate sits relative to them. Further down the same panel: Beta-Glucan, Eclipta Prostrata Extract and Laminaria Japonica Extract.

Ingredient list read from inkeedecoder.com on 10 September 2026.
51 of 52 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.
- Sodium Cocoyl Isethionate surfactant
- Sodium Cocoyl Isethionate is a coconut-derived surfactant that gives a dense, creamy foam while staying mild. It is the usual choice in syndet cleansing bars.
- 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.
- Sodium Methyl Cocoyl Taurate surfactant
- Sodium Methyl Cocoyl Taurate is a mild coconut-derived surfactant known for a rich, creamy lather that rinses without tightness.
- Glycol Distearate emollient
- A wax-like ester that thickens a cleanser and gives it a pearly opacity. It also leaves a conditioned feel behind after rinsing.
- Potassium Cocoate surfactant
- Potassium Cocoate is coconut oil turned into soap. It cleanses strongly and sits at a high pH, which is what gives a traditional soap-style cleanser its squeaky finish.
- Potassium Cocoyl Glycinate surfactant
- Potassium Cocoyl Glycinate is a coconut-and-glycine surfactant used in low-pH cleansers. It foams well and rinses without the squeaky tightness a soap leaves.
- Caprylyl/Capryl Glucoside surfactant
- Caprylyl/Capryl Glucoside is a sugar-derived cleansing surfactant. It foams modestly and is mild enough for low-pH cleansers built for reactive 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.
- 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.
- Hydroxypropyltrimonium Hyaluronate humectant
- Hydroxypropyltrimonium Hyaluronate carries a positive charge, and skin carries a slight negative one, so it is attracted to the surface and stays through rinsing. It is the hyaluronic used where a formula gets washed off.
- Sodium Hyaluronate Crosspolymer humectant
- Sodium Hyaluronate Crosspolymer is hyaluronic acid linked into a mesh. It holds water in a soft gel on the surface rather than sinking in, and it releases that water slowly through the day.
39 more explained
- Hyaluronic Acid humectant
- Hyaluronic Acid is a sugar chain the body already makes, and one gram of it can hold several litres of water. In a formula it is a humectant that pulls water to the surface of skin and holds it in a film, which is what makes skin look plumper while it is there.
- Sodium Acetylated Hyaluronate humectant
- Sodium Acetylated Hyaluronate is hyaluronic acid modified to be part oil-loving, so it clings to skin instead of rinsing away. Formulators call it the one that stays put.
- Potassium Hyaluronate humectant
- Potassium Hyaluronate is another salt of hyaluronic acid, used for the same reason as the sodium form: it dissolves easily and holds a large amount of water in the outer layer of skin.
- 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.
- 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.
- 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.
- Amaranthus Caudatus Seed Extract plant extract
- Amaranth seed extract, carrying squalene, sterols and peptides. It is used as a conditioning extract.
- 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.
- Ficus Carica (Fig) Fruit Extract plant extract
- Fig Fruit Extract carries fruit sugars, mild acids and a protein-digesting enzyme. It is used as a hydrating extract with a light smoothing effect.
- 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.
- 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 amino acid
- Glycine is the smallest amino acid and one of the free amino acids skin holds to keep water in the outer layer. In a formula it is a humectant and a mild buffer.
- Serine amino acid
- Serine is one of the most abundant free amino acids in the outer layer of skin, where it helps hold water. Added to a formula it is a humectant.
- Glutamic Acid amino acid
- Glutamic Acid is an amino acid used as a humectant and a mild pH adjuster. It is one of the components of skin's natural moisturising factor.
- Aspartic Acid amino acid
- Aspartic Acid is an amino acid used as a humectant and buffer, usually within a wider amino acid blend.
- Leucine amino acid
- Leucine is an essential amino acid used as a humectant, part of the amino acid block many Korean essences carry.
- Alanine amino acid
- Alanine is a free amino acid skin uses as part of its own moisture-holding system. In a formula it hydrates and conditions.
- 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.
- Lysine amino acid
- Lysine is an essential amino acid used as a conditioning humectant in an amino acid complex.
- Isoleucine amino acid
- Isoleucine is an essential amino acid used as a conditioning humectant within an amino acid complex.
- Phenylalanine amino acid
- Phenylalanine is an essential amino acid used in skincare as a conditioning humectant.
- Proline amino acid
- Proline is an amino acid abundant in collagen and one of skin's own humectants. Added to a formula it holds water in the outer layer.
- Threonine amino acid
- Threonine is an essential amino acid used in skincare as a humectant, normally as part of an amino acid complex rather than alone.
- Tyrosine amino acid
- Tyrosine is an amino acid used as a conditioning humectant in amino acid complexes.
- Valine amino acid
- Valine is an essential amino acid used as a humectant alongside the rest of an amino acid block.
- Histidine amino acid
- Histidine is an amino acid used as a humectant and a buffer, part of skin's own free amino acid pool.
- Cysteine amino acid
- Cysteine is a sulphur-bearing amino acid used as a humectant and antioxidant. It is one of the three building blocks of glutathione.
- Methionine amino acid
- Methionine is a sulphur-bearing essential amino acid used as a humectant and mild antioxidant.
- Dipotassium Glycyrrhizate active
- Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is the licorice fraction Korean formulas use for the look of redness, and it is far more stable in water than the whole extract.
- 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.
- 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.
- 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.
- Fructooligosaccharides humectant
- Fructooligosaccharides are short fructose chains used as humectants and as food for the skin's own resident microbes.
- 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.
- Oryza Sativa (Rice) Bran Extract plant extract
- Rice bran extract, from the outer layer milled off white rice. Bran is the richest part of the grain, carrying ferulic acid, vitamin E and phytic acid.
- 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.
- Sodium Chloride thickener
- Sodium Chloride is salt. In a cleanser it thickens the liquid; in a mask or essence it balances the mineral content of the water phase. It has no active role.
- 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 the Hyaluronic Acid Low-pH Cleansing Foam as your first step, morning and evening, on a face already wet with lukewarm water.
- A short pump or a pea of product is enough. Work it into a lather in wet hands for about twenty seconds before it touches the face.
- Rinse with lukewarm water and go straight on to your toner while skin is still damp, because a humectant layer has more to hold on to on a damp face.
- Twice a day is the ceiling. Do not follow it with a second cleanse in the morning, when there is no sunscreen or makeup left on the face to remove.
Worth knowing
- Patch test this foam cleanser on a small area and wait a day before using it more widely, especially with Sodium Hyaluronate on the list.
- Introduce this foam cleanser on its own for the first week, so anything your skin does is traceable to the Sodium Hyaluronate rather than to three changes at once.
