Where does this wash-off mask go in my routine?

After cleansing, and the rest of the routine goes on after you take the wash-off 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 Artemisia Princeps Leaf Extract and not three changes at once.

What else is on the list besides Artemisia Princeps Leaf Extract?

Allantoin, Beta-Glucan and Castanea Crenata (Chestnut) Shell Extract. The order they are printed in on this wash-off mask's panel is the order on the box, so you can see where Artemisia Princeps Leaf Extract sits relative to them. Further down the same panel: Origanum Vulgare Leaf Extract, Chamaecyparis Obtusa Leaf Extract and Salix Alba (Willow) Bark Extract.

Isntree Mugwort Calming Clay Mask 100ml

37 of 38 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.
Kaolin absorbent: Kaolin is white clay, the mildest of the cosmetic clays. It absorbs oil and lifts loose debris from the surface without stripping, which is why it is the clay used on drier 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.
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.
Bentonite absorbent: Bentonite is a volcanic clay that swells in water. It absorbs oil, thickens a mask, and holds pigments and powders evenly suspended.
Artemisia Princeps 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.
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.
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.
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.
Illite absorbent: Illite is a clay, often sold as French green clay. It takes up oil and water, which is why it appears in wash-off masks and powder cleansers.
Artemisia Princeps Leaf Powder absorbent: Korean mugwort leaf ground to a powder. In a formula it is a mild physical grain and an absorbent, and it colours the product green.
Camellia Sinensis Leaf Water plant extract: Camellia Sinensis Leaf Water is green tea distillate used in place of plain water as a base. It is far more dilute than the extract, so it sets the base rather than supplying the antioxidants.

25 more explained

Castanea Crenata (Chestnut) Shell Extract plant extract: Chestnut Shell Extract carries tannins and is used as an antioxidant plant extract, most often in formulas aimed at visible pores.
Origanum Vulgare Leaf Extract plant extract: Oregano leaf extract, rich in the phenols carvacrol and thymol. It is used as an antioxidant plant extract and brings its own herbal scent with it.
Chamaecyparis Obtusa Leaf Extract plant extract: Chamaecyparis Obtusa is hinoki cypress. Its leaf extract carries aromatic plant compounds and is used in Korean formulas aimed at oily, congested skin.
Salix Alba (Willow) Bark Extract plant extract: Willow Bark Extract carries salicin, the plant compound salicylic acid is related to. The two are not interchangeable: willow bark is a mild clarifying extract, not a BHA exfoliant at the levels used in cosmetics.
Avena Sativa (Oat) Kernel Extract plant extract: Oat Kernel Extract carries beta-glucan and avenanthramides, and it is one of the most reliably tolerated ingredients in skincare. It is used for the look of reddened, itchy-feeling skin.
Cynara Scolymus (Artichoke) Leaf Extract plant extract: Artichoke Leaf Extract carries cynaropicrin and other plant antioxidants. It is used in formulas aimed at the look of visible pores and dullness.
Lactobacillus/Soybean Ferment Extract ferment: This is soybean fermented by lactobacillus. The fermentation breaks soy proteins into smaller pieces, which is what makes the extract easier for a formula to carry.
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.
Cinnamomum Cassia Bark Extract plant extract: Cassia cinnamon bark extract, a traditional herbal ingredient carrying cinnamaldehyde and tannins. It is used in warming, antioxidant-rich blends.
Scutellaria Baicalensis Root Extract plant extract: Scutellaria Baicalensis is Chinese skullcap. Its root extract carries baicalin, a well studied plant antioxidant, and it is used for the look of redness.
Montmorillonite absorbent: A swelling clay that takes up many times its own weight in water. It absorbs oil in a mask and thickens an oil phase in a stick.
Phaseolus Angularis Seed Powder absorbent: Adzuki bean ground to a powder. In a formula it is the physical grain of a scrub and an absorbent that takes up a little oil.
Canadian Colloidal Clay absorbent: A fine mineral clay sold by its place of origin rather than its mineral name. Like the other cosmetic clays it absorbs oil and thickens a mask.
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.
Beta-Glucan polysaccharide: Beta-Glucan is a polysaccharide from oats or yeast. It holds a large amount of water, forms a soothing film, and is one of the ingredients formulators reach for in products aimed at reactive skin.
Methylpropanediol humectant: Methylpropanediol is a small glycol used to hydrate and to help water-soluble actives penetrate the outer layer of skin more evenly. It leaves almost no tack, which suits watery textures.
Algin thickener: Algin is a brown-seaweed polysaccharide. It thickens, forms a film, and sets into a rubbery gel when calcium is added, which is how a peel-off modelling mask works.
Magnesium Aluminum Silicate thickener: A refined clay mineral used to thicken water and hold powders and pigments suspended so a formula does not separate.
Cetyl Alcohol fatty alcohol: Cetyl Alcohol is a waxy fatty alcohol from coconut or palm, unrelated to drying ethanol. It thickens creams, stabilises the emulsion and leaves skin feeling softer.
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.
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.
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.
Tromethamine pH adjuster: Tromethamine neutralises acidic thickeners such as carbomer so they gel, and holds a formula near skin-friendly pH. It is used at a fraction of a percent.
Polyquaternium-51 film former: Polyquaternium-51 is a polymer, sometimes sold as Lipidure, built on the same phosphorylcholine structure as a cell membrane. It holds water in a film on the surface and gives a distinctive soft, dry 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.

How it works

The Mugwort Calming Clay Mask is a 100ml wash-off mask, used after cleansing. The plant extract it is built around is Artemisia Princeps Leaf Extract, named sixth on its own ingredient list. The same list carries Allantoin, Beta-Glucan and Castanea Crenata (Chestnut) Shell Extract, so the plant extract is not the only thing on it worth naming. How much of the Artemisia Princeps Leaf Extract stays on the skin, and for how long, is decided by the wash-off mask format rather than by the list alone. Isntree sells this Artemisia Princeps Leaf Extract wash-off mask in Korea, and this is that version.

How to use

Use the Mugwort Calming Clay Mask after cleansing.
A thin even layer over the areas you want it on, kept clear of the eye area and the lips.
Rinse with lukewarm water at the time the pack gives, then go straight into a hydrating layer and your moisturizer the same evening.
Once or twice a week. Do not leave it on longer than the pack says in the hope of more effect; a mask past its time works against the surface it is on.

Worth knowing

Patch test on the inner arm before a first full-face application if skin tends to react easily.
Store away from direct sunlight and high heat to keep the texture and scent stable over time.
Introduce one new active at a time when adding this into an existing routine.

Additionally, it has been shown to improve dry skin in those with atopic dermatitis. It also can be good for those with acne-prone skin because of the antibacterial and anti-inflammatory benefits.
Marisa K. Garshick, MDDermatologist, The Zoe Report
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.
