Key actives
Inonotus 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.
Rosmarinus 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.
Centella 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.
Glycyrrhiza 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.
Olea 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.
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.
Where does this wash-off mask go in my routine?
After cleansing, in place of the toner step, on one or two evenings a week. Toner goes on before it, 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.

How it works
The Bulgarian Rose Pore Tightening Clay Pack is a 100ml wash-off mask, used after cleansing, in place of the toner step, on one or two evenings a week. 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.
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.
