How it works
Allantoin is named on the ingredient panel on this sheet mask. 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. On this panel it sits alongside Pulsatilla Koreana Extract, Usnea Barbata Extract and Zanthoxylum Piperitum Fruit Extract. Korean pasque flower extract, a native anemone relative. It is used as a conditioning plant extract, usually beside other Korean herbal extracts.

Inside the formula
Inside the formula
What does Allantoin do in this sheet mask?
Allantoin sits in the middle of the ingredient list as a settling, comfort-focused ingredient common across Korean toners and creams.
Is Adenosine also in this formula?
Adenosine sits in the middle of the ingredient list. It is a wrinkle-care ingredient in Korea, included here for fine-line support rather than as a filler. It sits alongside Allantoin on MEDIHEAL's ingredient list for this product.
How is this sheet mask used in a routine?
Unfold the sheet and smooth it onto a cleansed face, adjusting it around the eyes, nose and mouth. Leave it on for 15 to 20 minutes, then remove and pat any remaining essence into the skin rather than rinsing it off. It works as an occasional, concentrated step layered over a completed routine, not a daily one.
Who is this sheet mask suited for?
Sensitive skin, Normal skin are the best fit for this sheet mask. Patch test on the inner arm before first full use, as with any new skincare product.

31 of 33 explained
- Aqua 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.
- Propylene Glycol humectant
- Propylene Glycol is a small glycol used as a humectant and solvent. It hydrates and helps actives dissolve; newer formulas often swap it for propanediol, which does the same job with a lighter feel.
- 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.
- 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.
- 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.
- 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.
- Pulsatilla Koreana Extract plant extract
- Korean pasque flower extract, a native anemone relative. It is used as a conditioning plant extract, usually beside other Korean herbal extracts.
- Usnea Barbata Extract plant extract
- Beard lichen extract, carrying usnic acid. It resists microbes, so formulas use it both as a plant extract and as part of a preservative system.
- Zanthoxylum Piperitum Fruit Extract plant extract
- Zanthoxylum Piperitum is Korean pepper. Its fruit extract is used as a conditioning plant extract and is often paired with pulsatilla and usnea in Korean formulas.
- 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.
- Bis-PEG-18 Methyl Ether Dimethyl Silane silicone
- A water-soluble silicone used for a light, silky slip without an oily film. It also helps other ingredients spread evenly.
- PEG-60 Hydrogenated Castor Oil emulsifier
- PEG-60 Hydrogenated Castor Oil is a castor-oil-derived solubiliser. It is what keeps fragrance and oil-soluble ingredients dissolved in a watery formula so it stays clear.
19 more explained
- 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.
- 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.
- Hydroxyethylcellulose thickener
- Hydroxyethylcellulose is a cellulose thickener that builds a clear, smooth gel and holds the rest of the formula in suspension.
- Sodium PCA humectant
- Sodium PCA is one of the substances skin makes for itself to hold water, part of what dermatology calls the natural moisturising factor. Added to a formula it is a strong humectant that suits skin that dehydrates quickly.
- 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.
- 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.
- 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.
- Phenoxyethanol preservative
- Phenoxyethanol is the most widely used cosmetic preservative outside the paraben family. It keeps a water-containing formula from growing bacteria and mould, and is capped at one percent in most markets, so it always sits low on a list.
- Punica Granatum Fruit Extract plant extract
- Pomegranate fruit extract, carrying ellagic acid and punicalagins. It is used as a plant antioxidant.
- 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.
- Alcohol solvent
- Alcohol here means ethanol. It dissolves ingredients water cannot, evaporates fast so a formula sets quickly and does not feel heavy, and thins texture. In quantity it can leave dry or reactive skin feeling tight, which is why many Korean formulas avoid it and some deliberately use it for a fast, weightless finish.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- Mentha Piperita Leaf Extract plant extract
- Peppermint leaf extract, the water-based extract rather than the essential oil, so it carries far less menthol. It is used as a refreshing herbal extract.
- Oryza Sativa Extract plant extract
- Rice Extract is the anchor of the Korean rice-skincare category. It carries starches, amino acids and ferulic acid, and it is used for the look of dullness and for a soft, blurred finish.
- 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.
- Natto Gum humectant
- Polyglutamic Acid comes from fermented soy and holds several times more water than hyaluronic acid for its weight. It forms a light film on the surface, so it is often layered with hyaluronic rather than replacing it.
- Xanthan Gum thickener
- Xanthan Gum is a polysaccharide made by fermenting sugar. It thickens a watery formula into a gel and holds the whole thing in suspension so nothing separates. Too much of it and a serum turns stringy, which is why it appears in fractions of a percent.
- Charcoal Powder absorbent
- Activated charcoal, a very porous carbon powder. Its surface binds oil and pigment, and it is what makes a mask or cleanser black.
