15Euterpe Oleracea (Acai) Fruit Extractplant extract
Acai fruit extract, from the Amazonian palm berry. It carries anthocyanins, the same purple pigment polyphenols found in blueberry, and is used as a plant antioxidant. It is named fifteenth on this sheet mask's list, alongside Arbutin.

Where each key active sits on the declared ingredient list, by entry number. Position is proportion: the further forward, the larger its share.
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 Arbutin and not three changes at once.
Does this sheet mask contain fragrance?
Yes. The ingredient list names Linalool. 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 sheet mask is not the one.
What else is on the list besides Arbutin?
Angelica Keiskei Extract, Olea Europaea (Olive) Leaf Extract and Euterpe Oleracea (Acai) Fruit Extract. The order they are printed in on this sheet mask's panel is the order on the box, so you can see where Arbutin sits relative to them. Further down the same panel: Vaccinium Angustifolium Fruit Extract, Vaccinium Macrocarpon (Cranberry) Fruit Extract and Rosmarinus Officinalis (Rosemary) Extract.
Not on the ingredient list below: fragrance or parfum, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

Ingredient list read from isoi.co.kr on 30 August 2026.
25 of 31 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.
- 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.
- Betaine humectant
- Betaine is a sugar-beet-derived humectant that cells use to hold water. In a formula it hydrates and takes the edge off cleansers and acids, which is why it often appears alongside them.
- Arbutin active
- Arbutin is the naturally occurring form of the same compound, from bearberry and related plants, used for the look of uneven tone. The alpha isomer is the more stable of the two.
- 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.
- 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.
- Angelica Keiskei Extract plant extract
- Ashitaba extract, a Japanese angelica relative rich in chalcones. It is used as an antioxidant conditioning extract.
- Rosa Damascena Flower Water plant extract
- Rosa Damascena Flower Water is the water left from distilling rose petals. It is used in place of plain water as a base and carries the scent and trace compounds of the distillation.
- 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.
- Euterpe Oleracea Fruit Extract plant extract
- Acai fruit extract, from the Amazonian palm berry. It carries anthocyanins, the same purple pigment polyphenols found in blueberry, and is used as a plant antioxidant.
- Vaccinium Angustifolium (Blueberry) Fruit Extract plant extract
- Lowbush blueberry fruit extract, high in anthocyanins. Berry extracts are used as plant antioxidants and can tint a formula.
13 more explained
- Vaccinium Macrocarpon (Cranberry) Fruit Extract plant extract
- Cranberry fruit extract, acidic and high in proanthocyanidins. It is used as an antioxidant berry extract.
- Rosmarinus Officinalis (Rosemary) Extract plant extract
- Rosemary extract with the plant part unstated. Rosemary carries rosmarinic and carnosic acid, and it is also used 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.
- Calendula Officinalis 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Linalool fragrance component
- Linalool is a floral aromatic found in lavender, bergamot and coriander. It is one of the 26 fragrance components EU labelling requires to be declared by name.

How it works
The Bulgarian Rose Blemish Care Mask is a sheet mask, used after toner, in place of your serum step, in the evening. The active it is built around is Arbutin, named fourth on its own ingredient list. The same list carries Angelica Keiskei Extract, Olea Europaea (Olive) Leaf Extract and Euterpe Oleracea (Acai) Fruit Extract, so the active is not the only thing on it worth naming. How much of the Arbutin stays on the skin, and for how long, is decided by the sheet mask format rather than by the list alone. isoi sells this Arbutin sheet mask in Korea, and this is that version.
How to use
- Apply to clean skin following the timing on the pack, then remove or rinse as directed. Most masks in this format are a once- or twice-weekly treatment step rather than a daily one.
Worth knowing
- Follow the timing on the pack; leaving a mask on well past the stated time does not add benefit and can irritate skin.

What professionals say
What professionals say
What skin-care professionals say about skin care, quoted from the medical sources linked beside each.
Arbutin works to inhibit tyrosinase, an enzyme present in melanocytes, the pigment-producing cells in the skin. This results in less pigment, dark spots and skin lightening.
Tiffany Jow Libby, MDBoard-certified dermatologist, mindbodygreen Pretty much every step of a Korean skin care routine is going to have some component of hydration.
