Key actives
11Adenosineactive
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. It is named eleventh on this sheet mask's list, alongside Allium Cepa (Onion) Bulb Extract.
13Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. The panel names it thirteenth on this sheet mask's list, beside Allium Cepa (Onion) Bulb Extract.
16Allium 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. It is the entry this sheet mask is named after, and the list carries it.
21Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named twenty-first on this sheet mask's list, alongside Allium Cepa (Onion) Bulb Extract.
22Nicotinamide Mononucleotideactive
Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself. The panel names it twenty-second on this sheet mask's list, beside Allium Cepa (Onion) Bulb Extract.

Where does this sheet mask go in my routine?
After toner, in place of your serum step, in the evening. Toner goes on before it, and the rest of the routine goes on after you take the sheet mask off. 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?
Adenosine, Dipotassium Glycyrrhizate and Niacinamide. The order they are printed in on this sheet mask'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: Nicotinamide Mononucleotide, Tranexamic Acid and Copper Tripeptide-1.

33 of 36 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Erythritol humectant
- Erythritol is a sugar alcohol humectant with a faint cooling feel as it dissolves. It hydrates and helps a formula spread without tack.
- 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.
- Polyglyceryl-10 Laurate emulsifier
- Polyglyceryl-10 Laurate is a sugar-derived emulsifier and solubiliser, mild enough to be a standard choice in Korean essences. It dissolves small amounts of oil into water without any tightening feel.
- 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.
- 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.
21 more explained
- 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.
- Dipropylene Glycol humectant
- Dipropylene Glycol is a glycol used as a solvent and a light humectant. Its main job is keeping the rest of the formula dissolved and the texture fluid rather than adding hydration of its own.
- 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.
- 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.
- Hydrolyzed Gardenia Florida Extract plant extract
- Hydrolyzed Gardenia Florida Extract is gardenia extract broken into smaller fragments so a water-based formula can carry it evenly.
- Maltodextrin film former
- Maltodextrin is a starch-derived sugar chain used to carry powdered extracts and to form a light film. It also gives a soft, smoothing feel.
- Ascorbic Acid antioxidant
- Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone.
- 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.
- Nicotinamide Mononucleotide active
- Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself.
- 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.
- Tocopherol antioxidant
- Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer.
- 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.
- Centella Asiatica Leaf 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.
- Dimethylsilanol Hyaluronate humectant
- Dimethylsilanol Hyaluronate is hyaluronic acid joined to a silicon-based group. It hydrates and leaves a smoother, silkier finish than hyaluronic acid alone.
- 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.
- 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.
- 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.
- 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.
- Copper Tripeptide-1 peptide
- Copper Tripeptide-1 is three amino acids bound to a copper ion, and the classic firming peptide in cosmetic chemistry. It is blue in solution, which is often why a serum carrying it is tinted, and it is used for the look of firmness and fine lines.
- 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.

How it works
The Onion Newpair Soothing Mask is a 5pads sheet mask, used after toner, in place of your serum step, in the evening. The plant extract it is built around is Allium Cepa (Onion) Bulb Extract, named sixteenth on its own ingredient list. The same list carries Adenosine, Dipotassium Glycyrrhizate and Niacinamide, 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 sheet mask format rather than by the list alone. Isntree sells this Allium Cepa (Onion) Bulb Extract sheet mask in Korea, and this is that version.
How to use
- Use the Onion Newpair Soothing Mask 25g x5ea after toner, in place of your serum step, in the evening.
- Unfold the sheet, line it up at the eyes first, then smooth it outward so no air is trapped underneath.
- Take it off at the time printed on the pack, pat in the essence left behind rather than rinsing, then go straight to your moisturizer.
- Two or three evenings a week is a normal rhythm. Do not leave it on past its time; a sheet that has gone dry takes moisture back off the face as it goes.
Worth knowing
- Patch test this sheet mask 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 sheet mask 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.
