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 Houttuynia Cordata Extract and not three changes at once.

What else is on the list besides Houttuynia Cordata Extract?

Allantoin, Ceramide NP and Glycosphingolipids. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Houttuynia Cordata Extract sits relative to them. Further down the same panel: Illicium Verum (Anise) Fruit Extract, Centella Asiatica Extract and Chamomilla Recutita (Matricaria) Flower Extract.

Key actives

1Houttuynia Cordata Extractplant 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. It is the entry this sheet mask is named after, and the list carries it.

10Illicium Verum (Anise) Fruit Extractplant extract

Star Anise Fruit Extract carries aromatic plant compounds. It is used as a conditioning extract and contributes scent. The panel names it tenth on this sheet mask's list, beside Houttuynia Cordata Extract.

11Allantoinactive

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. It is named eleventh on this sheet mask's list, alongside Houttuynia Cordata Extract.

All products with Allantoin

17Ceramide NPbarrier lipid

Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy. It is named seventeenth on this sheet mask's list, alongside Houttuynia Cordata Extract.

18Glycosphingolipidsbarrier lipid

Glycosphingolipids are ceramide-family lipids carrying a sugar group. They belong to the same lipid structure between skin cells and are used to make a formula feel more conditioning. The panel names it eighteenth on this sheet mask's list, beside Houttuynia Cordata Extract.

Anua Heartleaf 77% Soothing Sheet Mask

25 of 25 explained

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.
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.
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.
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.
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.
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.
Caprylyl Glycol preservative booster: Caprylyl Glycol is a glycol that conditions skin and, more importantly, strengthens a preservative system so less of the traditional preservative is needed. It appears in most modern formulas built without parabens.
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.
Illicium Verum (Anise) Fruit Extract plant extract: Star Anise Fruit Extract carries aromatic plant compounds. It is used as a conditioning extract and contributes scent.
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.
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.

13 more explained

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.
Chamomilla Recutita (Matricaria) Flower Extract plant extract: Chamomile Flower Extract is one of the oldest ingredients in skincare, carrying bisabolol and chamazulene. It is used for the look of redness in formulas for reactive skin.
Hippophae Rhamnoides Fruit Extract plant extract: Sea Buckthorn Fruit Extract is high in vitamin C and carotenoids, which give it a strong orange colour. It is used as an antioxidant extract.
Hamamelis Virginiana (Witch Hazel) Leaf Extract plant extract: Witch hazel leaf extract, taken from the leaf rather than the bark. Like the bark it carries tannins and gives an astringent feel.
Ceramide NP barrier lipid: Ceramide NP is the most used cosmetic ceramide, the same class of lipid that makes up roughly half the mortar between cells in the outer layer of skin. Added to a cream it slots into that structure, which is why ceramide formulas feel less leaky rather than merely greasy.
Glycosphingolipids barrier lipid: Glycosphingolipids are ceramide-family lipids carrying a sugar group. They belong to the same lipid structure between skin cells and are used to make a formula feel more conditioning.
Hydrogenated Lecithin emulsifier: Hydrogenated Lecithin is lecithin with its unsaturated bonds filled in, which makes it far more stable. It emulsifies and is the standard shell for the liposomes that carry actives into the outer layer of skin.
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.
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.
Polyglyceryl-4 Caprate emulsifier: Polyglyceryl-4 Caprate is a mild sugar-derived solubiliser used to dissolve fragrance and oil into watery formulas.
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.
Squalane emollient: Squalane is the stable, saturated version of squalene, a lipid human skin already makes. It is a light emollient that absorbs quickly, does not oxidise, and is one of the few oils widely considered safe for blemish-prone skin. Most cosmetic squalane is now from sugarcane or olive rather than shark.

How it works

The Heartleaf 77% Soothing Sheet Mask is a 1ea sheet mask, used after toner, in place of your serum step, in the evening. The plant extract it is built around is Houttuynia Cordata Extract, named first on its own ingredient list. The same list carries Allantoin, Ceramide NP and Glycosphingolipids, so the plant extract is not the only thing on it worth naming. How much of the Houttuynia Cordata Extract stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. Anua sells this Houttuynia Cordata Extract sheet mask in Korea, and this is that version.

How to use

Use the Heartleaf 77% Soothing Sheet Mask 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 Houttuynia Cordata Extract on the list.
Introduce this sheet mask on its own for the first week, so anything your skin does is traceable to the Houttuynia Cordata Extract rather than to three changes at once.

What professionals say

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.

Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic
Ceramides are part fatty acid and part amino acid and are able to be the grout that keeps the building blocks of the skin together and functioning as a barrier between the inside and outside world.
Amy Kassouf, MDDermatologist, Cleveland Clinic

1 more professional perspective

Its potential for skincare is promoted because of its anti-inflammatory (think blemishes, rashes, eczema) and hydrating properties.
