How it works
The Fact Man Blemish Care All-in-One Serum is a 100ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Arbutin, named seventh on its own ingredient list. The same list carries Allantoin, Avena Sativa (Oat) Kernel Extract and Rubus Idaeus (Raspberry) 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 serum format rather than by the list alone. isoi sells this Arbutin serum in Korea, and this is that version.
Key benefits
- Arbutin, the active this serum is built around
- Allantoin on the same list, an active
- Avena Sativa (Oat) Kernel Extract, Rubus Idaeus (Raspberry) Fruit Extract and Angelica Keiskei Extract on the same list, plant extracts
- Bambusa Vulgaris Extract and Camellia Sinensis Leaf Extract further down the same list
- Artemisia Princeps Leaf Extract and Calendula Officinalis Flower Extract further down the same list
- Arbutin named seventh on the manufacturer list printed on this page
How to use
- Apply morning and night after toner or essence and before moisturizer, pressing a small amount into the skin and letting it absorb fully before the next step.
Where does this serum go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than a serum goes on before it, and anything richer goes on after. 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 serum contain fragrance?
Yes. The ingredient list names Citral, Limonene and Linalool. 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 serum is not the one.
What else is on the list besides Arbutin?
Allantoin, Avena Sativa (Oat) Kernel Extract and Rubus Idaeus (Raspberry) Fruit Extract. The order they are printed in on this serum's panel is the order on the box, so you can see where Arbutin sits relative to them. Further down the same panel: Angelica Keiskei Extract, Bambusa Vulgaris Extract and Camellia Sinensis Leaf Extract.
Not on the ingredient list below: fragrance or parfum, silicones, parabens, sulfate surfactants, mineral oil or petrolatum and added color.

31 of 32 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.
- Ethanol 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.
- 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.
- 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.
- 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.
- Trehalose humectant
- Trehalose is a sugar that some desert plants use to survive drying out. In skincare it is a humectant that holds water in the outer layer and helps a formula feel comfortable rather than tight.
- 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.
- 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.
- 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.
- Rubus Idaeus (Raspberry) Fruit Extract plant extract
- Raspberry fruit extract, carrying fruit acids, sugars and anthocyanins. It is used as an antioxidant-rich conditioning extract.
19 more explained
- Angelica Keiskei Extract plant extract
- Ashitaba extract, a Japanese angelica relative rich in chalcones. It is used as an antioxidant conditioning extract.
- Bambusa Vulgaris Extract plant extract
- Bamboo extract. Bamboo concentrates silica as it grows, so the extract is used as a hydrating, mineral-bearing ingredient.
- Camellia Sinensis Leaf Extract plant extract
- Camellia Sinensis is the tea plant. Green tea leaf extract carries catechins, among the most studied plant antioxidants, and is used for the look of redness and oily shine.
- Artemisia Princeps (Mugwort) Leaf 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.
- 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.
- Arginine amino acid
- Arginine is an amino acid that does two jobs here: it holds water in the outer layer of skin, and it neutralises acidic gelling agents, which is why it often stands in for a synthetic pH adjuster.
- Carbomer thickener
- Carbomer is a synthetic polymer that only gels once a base neutralises it, which is why arginine or tromethamine sits nearby on the list. It gives the clear, non-stringy gel texture a xanthan formula cannot reach.
- 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.
- Sorbitan Sesquioleate emulsifier
- Sorbitan Sesquioleate is a water-in-oil emulsifier and pigment disperser. Cleansing oils use it so water can be worked into the oil at the rinse.
- 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.
- 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.
- 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.
- 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.
- Citral fragrance component
- Citral is a sharp lemon aromatic found in lemongrass and citrus oils. It is one of the 26 fragrance components EU labelling requires to be named.

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.
