Key actives
Arbutinactive
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. On this serum's own ingredient list it is named seventh.
Allantoinactive
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. The panel names it tenth on this serum's list, beside Arbutin.
Avena Sativa (Oat) Kernel Extractplant 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. The panel names it eleventh on this serum's list, beside Arbutin.
Rubus Idaeus (Raspberry) Fruit Extractplant extract
Raspberry fruit extract, carrying fruit acids, sugars and anthocyanins. It is used as an antioxidant-rich conditioning extract. It is named twelfth on this serum's list, alongside Arbutin.
Angelica Keiskei Extractplant extract
Ashitaba extract, a Japanese angelica relative rich in chalcones. It is used as an antioxidant conditioning extract. The panel names it thirteenth on this serum's list, beside Arbutin.
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.

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.
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.

What professionals say
What professionals say
What skin-care professionals say about the key actives in this formula, 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 Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic
1 more professional perspective
It’s an excellent skin protectant. It can moisturize inflamed or irritated skin very well.
