How it works
The Bulgarian Rose Whitening Laser Spot is a 20ml product. The active it is built around is Arbutin, named seventh on its own ingredient list. The same list carries Allantoin, Olea Europaea (Olive) Leaf Extract and Calendula Officinalis Flower 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 product format rather than by the list alone. This is the Original Korean Formula, the product isoi sells in Korea, Arbutin and all.
Key benefits
- Arbutin, the active this product is built around
- Allantoin on the same list, an active
- Olea Europaea (Olive) Leaf Extract, Calendula Officinalis Flower Extract and Scutellaria Baicalensis Root Extract on the same list, plant extracts
- Paeonia Suffruticosa Root Extract and Glycyrrhiza Glabra (Licorice) Root Extract further down the same list
- Cetyl Ethylhexanoate and Macadamia Ternifolia Seed Oil further down the same list
- Arbutin named seventh on the manufacturer list printed on this page
How to use
- Dab a small amount directly onto the area of concern after your other routine steps, morning and night, rather than spreading it over the whole face.
Is this the Korean-market product or a US version?
The Korean-market one, Arbutin and all. We match this product to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
Does this product contain fragrance?
Yes. The ingredient list names Citronellol and Geraniol. They sit 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 product is not the one.
What else is on the list besides Arbutin?
Allantoin, Olea Europaea (Olive) Leaf Extract and Calendula Officinalis Flower Extract. The order they are printed in on this product's panel is the order on the box, so you can see where Arbutin sits relative to them. Further down the same panel: Scutellaria Baicalensis Root Extract, Paeonia Suffruticosa Root Extract and Glycyrrhiza Glabra (Licorice) Root Extract.
Not on the ingredient list below: fragrance or parfum, denatured or SD alcohol, silicones, parabens, sulfate surfactants and mineral oil or petrolatum.

32 of 37 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.
- Caprylic/Capric Triglyceride emollient
- Caprylic/Capric Triglyceride is the light fraction of coconut oil, with the heavy parts removed. It is the workhorse emollient of modern formulas: it softens skin, dissolves oil-soluble actives and absorbs without the greasy weight of a whole plant oil.
- 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.
- Macadamia Ternifolia Seed Oil emollient
- Macadamia Seed Oil is unusually high in palmitoleic acid, a fatty acid that human sebum also contains, which is why it absorbs faster than most nut oils. It is a cushioning emollient for dry skin.
- 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.
- 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.
- 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.
- 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.
- 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.
- 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.
- Arachidyl Alcohol fatty alcohol
- Arachidyl Alcohol is a long-chain fatty alcohol used as a thickener and emollient, usually alongside behenyl alcohol.
20 more explained
- 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.
- Polyglyceryl-3 Methylglucose Distearate emulsifier
- Polyglyceryl-3 Methylglucose Distearate is a sugar-derived emulsifier known for a light, non-soapy feel. It builds gel-creams that do not read as rich.
- 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.
- Arachidyl Glucoside emulsifier
- Arachidyl Glucoside is a sugar-derived co-emulsifier, usually supplied with arachidyl and behenyl alcohols as a plant-based cream base.
- 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.
- Simmondsia Chinensis (Jojoba) Seed Oil emollient
- Jojoba Oil is a liquid wax rather than a true oil, and its structure is close to human sebum, which is why it absorbs so readily. It is an emollient that leaves a soft, non-greasy finish.
- 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.
- 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.
- Hippophae Rhamnoides (Sea Buckthorn) Fruit Oil emollient
- Oil from the pulp of the sea buckthorn berry rather than from its seed. The pulp oil is the richer and more strongly coloured of the two.
- 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.
- 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.
- 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.
- 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.
- 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.
- Citronellol fragrance component
- Citronellol is a rose-geranium aromatic and one of the 26 fragrance components EU labelling names individually.
- Geraniol fragrance component
- Geraniol is a rose-scented aromatic found in geranium and citronella oils. It is one of the 26 declarable fragrance components.

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.
