How it works

The Yuja C Serum is a 50ml serum, used after toner and before moisturizer, morning and evening. The plant extract it is built around is Citrus Junos Fruit Extract, named twenty-first on its own ingredient list. The same list carries Niacinamide, Adenosine and 3-O-Ethyl Ascorbic Acid, so the plant extract is not the only thing on it worth naming. How much of the Citrus Junos Fruit Extract stays on the skin, and for how long, is decided by the serum format rather than by the list alone. HANYUL sells this Citrus Junos Fruit Extract serum in Korea, and this is that version.

Key actives

Citrus Junos Fruit Extractplant extract

Yuja fruit extract, the Korean citrus preserved as yuja tea. It carries vitamin C, fruit acids and flavonoids. The name on the box points at it, and it is named twenty-first on this serum's own ingredient list.

Niacinamideactive

Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. The panel names it fifth on this serum's list, beside Citrus Junos Fruit Extract.

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 twentieth on this serum's list, beside Citrus Junos Fruit Extract.

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. The panel names it twenty-fourth on this serum's list, beside Citrus Junos Fruit Extract.

Beta-Caroteneantioxidant

Beta-Carotene is an orange plant pigment and a vitamin A precursor. It is used as an antioxidant and it tints a formula, which is often why it is there. The panel names it twenty-sixth on this serum's list, beside Citrus Junos Fruit Extract.

How to use

  1. Use this serum AM and/or PM, as the serum step, after toner or essence and before moisturizer. Pat or smooth it on rather than rubbing, and give it a moment to settle before layering the next step.

Worth knowing

  • Patch test this serum on a small area and wait a day before using it more widely, especially with Citrus Junos Fruit Extract on the list.
  • This list names Limonene and Linalool, so skip it if fragrance components are something you avoid.
