How it works
A creamy cleanser is built on a soap base rather than a modern surfactant blend, and this one is no exception: stearic, myristic and lauric acid meet potassium hydroxide in the formula and whip into a dense, low-squeak foam. Hyaluronic acid and panthenol are on the same list, which is what keeps the rinse from finishing tight. It goes first in the routine, morning and evening, on a face already wet with warm water. It suits skin that finds a clear gel drying and does not want an oil cleanse in the morning. Follow it with toner while the face is still damp.
Key benefits
- Three hyaluronic entries and panthenol close out the list
- A dense soap-style lather softened with glycinate and glucoside surfactants
- Rinses to a moist, comfortable finish rather than a squeak
- Suits AM and PM use for normal to dry skin
Inside the formula
Inside the formula
COSRX Hydrium Triple Hyaluronic Moisturizing Cleanser
What makes this a fatty-acid cleanser rather than a foaming cleanser?
The formula is built on stearic, myristic, lauric and palmitic acid combined with potassium hydroxide, which is the classic soap-making reaction: a fatty acid plus an alkali forms a potassium soap in the jar. That gives a creamier, lower-foam wash than a sulfate or amino-acid surfactant cleanser, closer in feel to a cleansing balm that rinses clean.
Does this cleanser contain hyaluronic acid, and does it matter in a rinse-off product?
Yes, the list carries hyaluronic acid, hydrolyzed hyaluronic acid and sodium hyaluronate near the end. In a cleanser these contribute during the brief window before rinsing, softening the wash rather than delivering the sustained hydration a leave-on serum provides, so the name Triple Hyaluronic describes the formula's composition rather than a leave-on treatment claim.
Is this cleanser fragrance-free?
No, fragrance appears roughly a third of the way down the list under the parfum labeling. Anyone avoiding scented cleansers on sensitive or reactive skin should be aware of this before choosing it.
Will this cleanser feel drying with daily use?
A potassium-soap base can feel more drying than a modern surfactant blend, but glycerin sits second on the list and hyaluronic acid and its salt forms appear near the end to offset that. Skin that already runs dry may still want to follow with a moisturizer right after rinsing, as with most soap-based cleansers.
Does this formula suit oily or combination skin better than dry skin?
The fatty-acid soap base cuts oil effectively, which tends to suit oilier skin, while the glycerin and hyaluronate content is there mainly to soften the rinse rather than to add lasting moisture. Combination and oily skin types are the better fit; very dry skin may prefer a cream or oil cleanser instead.

27 of 27 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.
- 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.
- Myristic Acid fatty acid
- Myristic Acid is a saturated fatty acid used to thicken and, with a base added, to build the foam in a soap-style cleanser.
- Lauric Acid fatty acid
- Lauric Acid is the coconut fatty acid that gives soap-style cleansers their dense foam. It is not well suited to blemish-prone skin at high levels.
- Potassium Hydroxide pH adjuster
- Potassium Hydroxide is a strong base used in traces to raise a formula to its target pH. In a soap-style cleanser it also converts fatty acids into the surfactant that does the cleansing.
- Palmitic Acid fatty acid
- Palmitic Acid is a saturated fatty acid present in skin's own lipids. It thickens a formula, stabilises the emulsion and softens skin.
- PotassiumCocoylGlycinate 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.
- Coco-Glucoside surfactant
- Coco-Glucoside is a mild sugar-derived surfactant used in gentle cleansers, usually with a second surfactant to build foam.
- 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.
- Fragrance(Parfum) fragrance
- Fragrance, or Parfum, is a single declaration standing for a whole scent blend, which can be dozens of materials. Regulators allow it as a trade secret, so a list showing only this word does not say what the scent is made of. It is the most common trigger named by people with reactive skin.
- Polyquaternium-7 film former
- Polyquaternium-7 is a positively charged polymer, so it clings to hair and skin, which carry a slight negative charge. It conditions and reduces static.
15 more explained
- Acrylates/C10-30 Alkyl AcrylateCrosspolymer 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.
- SodiumCocoylIsethionate 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.
- Arachidic Acid fatty acid
- Arachidic Acid is a long-chain saturated fatty acid used to thicken and stabilise a formula.
- 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.
- 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.
- 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.
- Sodium Benzoate preservative
- Sodium Benzoate is a mild preservative that works only in acidic formulas. It is usually paired with potassium sorbate, and the pair is the standard choice where a brand wants no phenoxyethanol.
- QuillajaSaponaria Bark Extract surfactant
- Soapbark extract, rich in natural saponins. Saponins foam in water, which is why this is used as a plant-derived cleansing agent rather than as a botanical.
- CitricAcid pH adjuster
- Citric Acid is used in tiny amounts to bring a formula to the pH its actives need, not as an exfoliant at that level. It is an AHA, so at much higher concentrations it can also exfoliate.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.

How to use
- Use the Hydrium Triple Hyaluronic Moisturizing Cleanser as your first step, morning and evening, on a wet face.
- A coin-sized amount, worked between wet palms until it turns dense, then massaged over the face in small circles.
- Rinse with lukewarm water and go to your toner while skin is still damp, so the layer above it has something to hold.
- Twice a day, every day. Do not finish with hot water; it undoes the point of a cleanser chosen for a soft rinse.
Worth knowing
- Fragrance is on the ingredient list.
