How it works
A reactive, overheated face after a long day, a strong active, or travel calls for a fifteen-minute reset, not a new step added to the routine. Centella asiatica extract sits second on this list, with niacinamide fifth and a triple-molecular-weight hyaluronic acid stack layering water at different depths underneath. Mugwort, wolfberry, purslane and ginseng round out the hanbang cast further down the list.
Key benefits
- Centella asiatica extract is the second ingredient, right after water
- Niacinamide is fifth, so the calming brief runs alongside a tone argument
- Three forms of hyaluronic acid, sodium hyaluronate, hydrolyzed hyaluronic acid and hyaluronic acid itself, layer hydration at different depths
- Mugwort, wolfberry, purslane and ginseng extracts carry the rest of the hanbang cast
- Sold as a single sheet here, not the brand's standard ten-pack box, so you can try it once before committing
- Wear fifteen to twenty minutes, then pat in what remains in the essence rather than rinsing it off

How to use
- Use it in the evening after toner, in place of your serum step.
- Line the sheet 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 and pat in what is left rather than rinsing.
- Do not leave it on until it dries out, since a dry sheet takes moisture back off the face.
How much centella asiatica extract is actually in this sheet mask?
Centella asiatica extract is declared at a stated percentage and sits second on the ingredient list, right after water, so it is the largest single active in the essence rather than a trace addition. Niacinamide follows at position five, which means the calming brief runs alongside a tone argument rather than standing alone.
Does this mask contain fragrance or added oils?
No parfum, fragrance, or essential oil appears anywhere on this mask's own ingredient list. What comfort the mask gives comes from the plant extracts and humectants themselves rather than a scent ingredient layered on top.
How many forms of hyaluronic acid does this mask carry?
Three separate hyaluronic acid entries run through the list: sodium hyaluronate, hydrolyzed hyaluronic acid, and hyaluronic acid itself. Each form differs in molecular weight, which is why a Korean sheet mask formula this size layers several rather than relying on just one.
Who is this sheet mask formulated for?
The formula is built around centella asiatica, mugwort, wolfberry, purslane, and ginseng extracts, a hanbang cast aimed at skin that looks red, sensitized, or dehydrated. It carries no added fragrance, which makes it a reasonable choice for anyone whose skin reacts to scented leave-on products.
How can I confirm this is the authentic Korean-market Beauty of Joseon formula, not a US reformulation?
Beauty of Joseon verifies its products by sourcing chain rather than a scan, because the brand has retired its own QR verification and is phasing out its authenticity seal. Your unit arrives with its Korean-market barcode and batch code intact, not swapped for an export label, and we publish exactly where we buy. That intact packaging is the record the brand itself points to now that its earlier scan-based check is gone.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

28 of 28 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.
- 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.
- Glycereth-26 humectant
- Glycereth-26 is a modified glycerin that hydrates with far less stickiness than glycerin itself. It is a common way to load water into a formula that has to stay light.
- 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.
- 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.
- 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.
- 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.
- Acrylates/C10-30 Alkyl Acrylate Crosspolymer 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.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Carrageenan thickener
- Carrageenan is a red-seaweed polysaccharide that thickens and forms a moisture-holding film. It gives a formula a slippery, cushioned body.
- Polyglyceryl-4 Caprate emulsifier
- Polyglyceryl-4 Caprate is a mild sugar-derived solubiliser used to dissolve fragrance and oil into watery formulas.
16 more explained
- Polyglyceryl-6 Caprylate emulsifier
- A polyglycerin emulsifier with a short fatty chain, which makes it more water-loving than its longer-chain relatives. It suits cleansing waters and micellar formulas.
- 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.
- 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.
- 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.
- Helianthus Annuus (Sunflower) Seed Oil emollient
- Sunflower Seed Oil is high in linoleic acid, the fatty acid dry and blemish-prone skin is often short of. It is a light, non-fragrant emollient and one of the better tolerated plant oils.
- 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.
- Artemisia Princeps Leaf Extract plant extract
- Artemisia Princeps is Korean mugwort, one of the country's oldest skincare and bathing plants. Its leaf extract is used for the look of reddened, reactive skin, and it is the ingredient behind the mugwort category.
- Lycium Chinense Fruit Extract plant extract
- Goji berry fruit extract, the gugija brewed as tea in Korea. It carries carotenoids and polysaccharides and is used as an antioxidant conditioning extract.
- Propanediol humectant
- Propanediol is a plant-derived glycol used in place of propylene glycol. It hydrates, carries actives into solution, and gives a lighter, less sticky slip than glycerin at the same strength.
- 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.
- Panax Ginseng Root Extract plant extract
- Ginseng Root Extract is the signature ingredient of Korean traditional skincare, carrying ginsenosides. It is used for the look of tired, dull skin, and brands often ferment it to break the ginsenosides into smaller forms.
- 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.
- Anthemis Nobilis Flower Oil fragrance component
- Anthemis Nobilis is Roman chamomile. The flower oil is an essential oil, so it scents a formula as well as conditioning it, and essential oils are the class most likely to bother 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.
- 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.

Worth knowing
- Follow the timing on the pack; leaving a treatment step on well past the stated time does not add benefit and can irritate skin.
- Patch-test on a small area first if you are new to this formula or to the brand.
- Centella Asiatica Extract and this formula's other named actives are new to your skin the first time you use it, so introduce it a few times a week before moving to daily use if your skin runs sensitive.
