How it works
The Bulgarian Rose Pore Tightening Clay Pack is a 100ml wash-off mask, used after cleansing. The plant extract it is built around is Inonotus Obliquus (Mushroom) Extract, named seventeenth on its own ingredient list. The same list carries Rosmarinus Officinalis (Rosemary) Leaf Extract, Centella Asiatica Extract and Glycyrrhiza Glabra (Licorice) Root Extract, so the plant extract is not the only thing on it worth naming. How much of the Inonotus Obliquus (Mushroom) Extract stays on the skin, and for how long, is decided by the wash-off mask format rather than by the list alone. This is the Original Korean Formula, the wash-off mask isoi sells in Korea, Inonotus Obliquus (Mushroom) Extract and all.

Key actives
17Inonotus Obliquus (Mushroom) Extractplant extract
Chaga mushroom extract, from the fungus that grows on birch. It carries beta glucan polysaccharides and melanin pigments, so it holds water and can darken a formula. On this wash-off mask's own ingredient list it is named seventeenth.
18Rosmarinus Officinalis (Rosemary) Leaf Extractplant extract
Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid. It is named eighteenth on this wash-off mask's list, alongside Inonotus Obliquus (Mushroom) Extract.
All products with Rosmarinus Officinalis (Rosemary) Leaf Extract
21Centella Asiatica Extractplant 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. The panel names it twenty-first on this wash-off mask's list, beside Inonotus Obliquus (Mushroom) Extract.
22Glycyrrhiza Glabra (Licorice) Root Extractplant extract
Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives. The panel names it twenty-second on this wash-off mask's list, beside Inonotus Obliquus (Mushroom) Extract.
All products with Glycyrrhiza Glabra (Licorice) Root Extract
24Olea Europaea (Olive) Leaf Extractplant extract
Olive leaf extract, carrying oleuropein. It is used as a plant antioxidant, and it is a different ingredient from the pressed fruit oil. It is named twenty-fourth on this wash-off mask's list, alongside Inonotus Obliquus (Mushroom) Extract.
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 Inonotus Obliquus (Mushroom) Extract and not three changes at once.
Is this the Korean-market wash-off mask or a US version?
The Korean-market one, Inonotus Obliquus (Mushroom) Extract and all. We match this wash-off mask to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
Does this wash-off mask contain fragrance?
Yes. The ingredient list names Limonene. It sits on the panel printed on this page, so you can read the position for yourself before you buy. If fragrance components are something you avoid, this wash-off mask is not the one.
What else is on the list besides Inonotus Obliquus (Mushroom) Extract?
Rosmarinus Officinalis (Rosemary) Leaf Extract, Centella Asiatica Extract and Glycyrrhiza Glabra (Licorice) Root 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 Inonotus Obliquus (Mushroom) Extract sits relative to them. Further down the same panel: Olea Europaea (Olive) Leaf Extract, Castanea Crenata (Chestnut) Shell Extract and Salix Alba (Willow) Bark Extract.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants and mineral oil or petrolatum.

Ingredient list read from isoi.co.kr on 30 August 2026.
34 of 40 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.
- Cetyl Ethylhexanoate emollient
- Cetyl Ethylhexanoate is a synthetic ester used as a dry-feeling emollient. It spreads easily, leaves a silky rather than oily finish, and helps disperse pigments and UV filters evenly.
- Cetearyl Alcohol fatty alcohol
- Cetearyl Alcohol is a waxy solid, not the drying kind of alcohol. It is a blend of cetyl and stearyl alcohols used to thicken a cream and keep oil and water from separating, and it softens skin as it does so.
- Pentaerythrityl Tetraisostearate emollient
- A thick, cushioned ester that gives lip and balm formulas their gloss and their cling. It is heavy enough to stay where it is put.
- Limnanthes Alba (Meadowfoam) Seed Oil emollient
- Meadowfoam Seed Oil is over 95 percent long-chain fatty acids, which makes it exceptionally stable against going rancid. It is an emollient that leaves a soft, sealed feel.
- Glyceryl Stearate emulsifier
- Glyceryl Stearate is glycerin joined to stearic acid, and one of the most used emulsifiers in skincare. It holds oil and water together and thickens the result, and it softens skin at the same time.
- Shea Butter emollient
- Shea Butter is the fat pressed from the shea nut, rich in oleic and stearic acids and unsaponifiable plant sterols. It is a heavy emollient and partial occlusive, which is why it sits in balms and night creams rather than in essences.
- Olea Europaea (Olive) Fruit Oil emollient
- Olive Fruit Oil is high in oleic acid and plant sterols. It is a rich emollient that suits dry skin and is heavy enough that blemish-prone skin often does not get on with it.
- Arachidyl Alcohol fatty alcohol
- Arachidyl Alcohol is a long-chain fatty alcohol used as a thickener and emollient, usually alongside behenyl alcohol.
- Behenyl Alcohol fatty alcohol
- Behenyl Alcohol is a long-chain fatty alcohol used to thicken and stabilise a cream. It gives a richer, more velvety body than cetyl alcohol.
22 more explained
- Arachidyl Glucoside emulsifier
- Arachidyl Glucoside is a sugar-derived co-emulsifier, usually supplied with arachidyl and behenyl alcohols as a plant-based cream base.
- Prunus Armeniaca (Apricot) Kernel Oil emollient
- Apricot kernel oil, a light oil high in oleic acid. It absorbs quickly and is used where a formula needs softening without heaviness.
- 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.
- Inonotus Obliquus (Chaga Mushroom) Extract plant extract
- Chaga mushroom extract, from the fungus that grows on birch. It carries beta glucan polysaccharides and melanin pigments, so it holds water and can darken a formula.
- Rosmarinus Officinalis (Rosemary) Leaf Extract plant extract
- Rosemary Leaf Extract carries rosmarinic and carnosic acids, both effective antioxidants. It is often there to keep the oils in a formula from going rancid.
- Chamomilla Recutita (Matricaria) Flower/Leaf Extract plant extract
- German chamomile, taken from flower and leaf together. It carries bisabolol and the blue azulenes and is used for the look of reactive, reddened 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.
- Glycyrrhiza Glabra (Licorice) Root Extract plant extract
- Licorice Root Extract carries glabridin and liquiritin. It is one of the classic plant ingredients used for the look of uneven tone and redness, and it appears in almost every brightening formula that avoids synthetic actives.
- Olea Europaea (Olive) Leaf Extract plant extract
- Olive leaf extract, carrying oleuropein. It is used as a plant antioxidant, and it is a different ingredient from the pressed fruit oil.
- Rosa Damascena Flower Oil fragrance component
- Rosa Damascena Flower Oil is rose essential oil, one of the most expensive materials in perfumery. It scents a formula, and like every essential oil it is a class reactive skin often does not tolerate.
- Castanea Crenata 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.
- 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.
- 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.
- Calendula Officinalis (Pot Marigold) Flower Extract plant extract
- Marigold flower extract, one of the oldest plant ingredients used for the look of reddened, easily bothered skin. It carries carotenoids and flavonoids.
- Citrus Aurantium Bergamia (Bergamot) Fruit Oil fragrance component
- Bergamot Fruit Oil is a citrus essential oil and the top note of eau de cologne. It scents a formula; citrus oils are the aromatic class most likely to bother reactive skin.
- Rosmarinus Officinalis (Rosemary) Leaf Oil fragrance component
- Rosemary Leaf Oil is an essential oil carrying camphor and cineole. It scents a formula and is a stronger aromatic than most.
- Pelargonium Graveolens Flower Oil fragrance component
- Pelargonium Graveolens is rose geranium. Its flower oil is an essential oil used to scent a formula, carrying citronellol and geraniol.
- Lavandula Angustifolia (Lavender) Oil fragrance component
- Lavender Oil is an essential oil carrying linalool and linalyl acetate. It scents a formula, and linalool is one of the fragrance components EU labelling requires to be named separately.
- 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.
- Paeonia Suffruticosa Root Extract plant extract
- Paeonia Suffruticosa is tree peony, a long-standing East Asian medicinal plant. Its root extract carries paeoniflorin and is used for the look of reddened skin.
- Limonene fragrance component
- Limonene is the citrus-peel aromatic. It appears here because EU labelling requires 26 fragrance components to be named individually rather than hidden inside "fragrance", and it is one of them.

How to use
- Apply an even layer over cleansed skin, avoiding the eye and lip area, leave on for the time stated on the packaging, then rinse thoroughly with lukewarm water.
Worth knowing
- Introduce any new product gradually rather than adding several new steps to a routine at once, so a reaction is easy to trace back to the right cause.
- Patch test on a small area first and wait a day before applying it to the full face, especially the first time you use it.
