How it works
The Vitamin C Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The antioxidant it is built around is Ascorbic Acid, named second on its own ingredient list. The same list carries Adenosine, 3-O-Ethyl Ascorbic Acid and Ferulic Acid, so the antioxidant is not the only thing on it worth naming. How much of the Ascorbic Acid stays on the skin, and for how long, is decided by the serum format rather than by the list alone. This is the Original Korean Formula, the serum Benton sells in Korea, Ascorbic Acid and all.

Key actives
Ascorbic Acidantioxidant
Ascorbic Acid is pure vitamin C, the most researched form and also the least stable: it needs a low pH and airtight packaging to stay active. It is an antioxidant used for the look of dullness and uneven tone. The name on the box points at it, and it is named second on this serum's own ingredient list.
Adenosineactive
Adenosine is a nucleoside that Korea's own cosmetic authority recognises as a wrinkle-care functional ingredient, which is why it appears on so many Korean lists at a low level. It is used for the look of fine lines and is stable and well tolerated. The panel names it fourteenth on this serum's list, beside Ascorbic Acid.
3-O-Ethyl Ascorbic Acidantioxidant
3-O-Ethyl Ascorbic Acid is a stable vitamin C derivative that skin converts to ascorbic acid. It survives in a formula far better than pure vitamin C and works at a gentler pH, so it suits skin that finds the pure acid uncomfortable. It is named eighth on this serum's list, alongside Ascorbic Acid.
Ferulic Acidantioxidant
Ferulic Acid is a plant antioxidant from bran and seeds. Its main formulation job is stabilising vitamins C and E so a serum keeps working for longer, which is why the three appear together so often. It is named fifteenth on this serum's list, alongside Ascorbic Acid.
Glutathioneantioxidant
Glutathione is a small peptide the body uses as one of its main antioxidants. In skincare it is used as an antioxidant and for the look of dullness; it is unstable in water, so formulas that carry it are usually built around protecting it. It is named seventeenth on this serum's list, alongside Ascorbic Acid.
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 Ascorbic Acid and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Ascorbic Acid and all. We match this serum to its Korean barcode before it reaches the shelf, which is the check that tells you which market release you are holding.
What else is on the list besides Ascorbic Acid?
Adenosine, 3-O-Ethyl Ascorbic Acid and Ferulic Acid. The order they are printed in on this serum's panel is the order on the box, so you can see where Ascorbic Acid sits relative to them. Further down the same panel: Glutathione, Tocotrienols and Tocopherol.

Payment and security

How to use
- Apply it after your toner, while the face is still slightly damp, so a thin layer spreads without dragging.
- Three or four drops cover the whole face; press it in with the flats of the fingers rather than rubbing.
- Follow with a moisturizer within a minute so the thin layer has something holding it down.
- Do not stack it under a second serum doing the same job, since more layers is not the same as more result.
Worth knowing
- New to this formula or to the brand: patch-test on the inner arm and wait a day before applying it to the face.
- Discontinue use and rinse the area with water if redness, itching or irritation develops.
