Key actives
4Allium Cepa (Onion) Bulb Extractplant extract
Onion Bulb Extract carries quercetin and sulphur compounds. Korean formulas use it for the look of blemish marks and uneven tone, and it is the namesake ingredient of the onion skincare line. The name on the box points at it, and it is named fourth on this foam cleanser's own ingredient list.
13Sodium Heparinpolysaccharide
Sodium Heparin is a sulfated sugar chain, structurally close to the heparan sulfate skin makes itself. In a formula it is a strong humectant. It is named thirteenth on this foam cleanser's list, alongside Allium Cepa (Onion) Bulb Extract.
14Allantoinactive
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. The panel names it fourteenth on this foam cleanser's list, beside Allium Cepa (Onion) Bulb Extract.
39Sodium Ascorbyl Phosphateantioxidant
Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging. The panel names it thirty-ninth on this foam cleanser's list, beside Allium Cepa (Onion) Bulb Extract.
40Tranexamic Acidactive
Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired. It is named fortieth on this foam cleanser's list, alongside Allium Cepa (Onion) Bulb Extract.

Isntree Onion Newpair Cleansing Foam 150ml
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 Allium Cepa (Onion) Bulb Extract and not three changes at once.
What else is on the list besides Allium Cepa (Onion) Bulb Extract?
Allantoin, Tranexamic Acid and Sodium Ascorbyl Phosphate. The order they are printed in on this foam cleanser's panel is the order on the box, so you can see where Allium Cepa (Onion) Bulb Extract sits relative to them. Further down the same panel: Sodium Heparin, Houttuynia Cordata Extract and Coccinia Indica Fruit Extract.

39 of 41 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.
- Potassium Myristate surfactant
- Potassium Myristate is the soap made from myristic acid. It gives a cleanser a dense, creamy lather, and being a soap it works at alkaline pH.
- Allium Cepa (Onion) Bulb Extract plant extract
- Onion Bulb Extract carries quercetin and sulphur compounds. Korean formulas use it for the look of blemish marks and uneven tone, and it is the namesake ingredient of the onion skincare line.
- 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.
- 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.
- 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.
- Coco-Betaine surfactant
- Coco-Betaine is a coconut-derived secondary surfactant used to build foam and make a cleanser milder.
- 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.
- Hydroxypropyl Starch Phosphate thickener
- Hydroxypropyl Starch Phosphate is a modified starch used to thicken and to take the sticky edge off a formula, leaving a powdery finish.
- Sodium Heparin polysaccharide
- Sodium Heparin is a sulfated sugar chain, structurally close to the heparan sulfate skin makes itself. In a formula it is a strong humectant.
27 more explained
- 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.
- 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.
- 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.
- Sodium C14-16 Olefin Sulfonate surfactant
- A strong anionic surfactant that foams heavily. It is a sulfate alternative in name but not in strength, and it is more common in shampoos than in facial cleansers.
- Sorbitol humectant
- Sorbitol is a sugar alcohol used as a humectant. It hydrates like glycerin with a smoother, less sticky finish, and it adds a little body to watery textures.
- Potassium Benzoate preservative
- The potassium salt of benzoic acid, used as a preservative. It only works in an acidic formula, which is why it turns up in low-pH products.
- 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.
- 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.
- 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.
- Coccinia Indica Fruit Extract plant extract
- Coccinia Indica is ivy gourd. Its fruit extract is used as a conditioning, hydrating plant extract in Korean formulas.
- 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.
- Eclipta Prostrata 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.
- Melia Azadirachta Leaf Extract plant extract
- Melia Azadirachta is neem. Its leaf and flower extracts are long-standing Ayurvedic ingredients, and Korean formulas use them in products aimed at the look of congested, blemish-prone skin.
- Hydrogenated Polydecene emollient
- Hydrogenated Polydecene is a synthetic hydrocarbon emollient used in place of mineral oil. It is stable, has no scent, and gives a cushioned slip without oxidising.
- Arachidic Acid fatty acid
- Arachidic Acid is a long-chain saturated fatty acid used to thicken and stabilise a formula.
- Sodium Citrate pH adjuster
- Sodium Citrate is the salt of citric acid, used as a buffer: it holds a formula at a steady pH rather than pushing it in one direction. It is also a mild chelator.
- Trisodium Ethylenediamine Disuccinate chelator
- A readily biodegradable chelator used in place of EDTA. It ties up trace metal ions in the water so they cannot spoil the formula.
- 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.
- Solanum Melongena (Eggplant) Fruit Extract plant extract
- Eggplant Fruit Extract carries nasunin, the antioxidant pigment in aubergine skin. It is used as an antioxidant plant extract.
- 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.
- Ocimum Sanctum Leaf Extract plant extract
- Ocimum Sanctum is holy basil, or tulsi. Its leaf extract carries plant antioxidants and is used in formulas built for the look of stressed, reactive skin.
- Citric Acid 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.
- Curcuma Longa (Turmeric) Root Extract plant extract
- Turmeric Root Extract carries curcuminoids, well studied plant antioxidants. It is used for the look of dullness and uneven tone, and it tints a formula faintly yellow.
- Corallina Officinalis Extract plant extract
- Corallina Officinalis is coral seaweed, which holds calcium and magnesium in its structure. Its extract is used as a mineral-rich conditioning ingredient.
- Sodium Ascorbyl Phosphate antioxidant
- Sodium Ascorbyl Phosphate is a water-soluble, stable vitamin C salt. It works at near-neutral pH, so it appears in formulas aimed at skin that pure ascorbic acid leaves stinging.
- Tranexamic Acid active
- Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired.
- 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.

How it works
The Onion Newpair Cleansing Foam is a 150ml foam cleanser, used as your first step, morning and evening, on a face already wet with lukewarm water. The plant extract it is built around is Allium Cepa (Onion) Bulb Extract, named fourth on its own ingredient list. The same list carries Allantoin, Tranexamic Acid and Sodium Ascorbyl Phosphate, so the plant extract is not the only thing on it worth naming. How much of the Allium Cepa (Onion) Bulb Extract stays on the skin, and for how long, is decided by the foam cleanser format rather than by the list alone. Isntree sells this Allium Cepa (Onion) Bulb Extract foam cleanser in Korea, and this is that version.
How to use
- Use the Onion Newpair 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 Allium Cepa (Onion) Bulb Extract on the list.
- Introduce this foam cleanser on its own for the first week, so anything your skin does is traceable to the Allium Cepa (Onion) Bulb Extract rather than to three changes at once.
