How it works
The Green Tangerine Vita-C E TXA Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Tranexamic Acid, named fifth on its own ingredient list. The same list carries Niacinamide, Adenosine and Nicotinamide Mononucleotide, so the active is not the only thing on it worth naming. How much of the Tranexamic 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 goodal sells in Korea, Tranexamic Acid and all.

Key actives
Tranexamic Acidactive
Tranexamic Acid is a synthetic amino acid derivative used for the look of stubborn discolouration and post-blemish marks. It is water soluble, stable and comfortable next to niacinamide, which is how it is usually paired. On this serum's own ingredient list it is named fifth.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named sixth on this serum's list, alongside Tranexamic Acid.
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 twenty-fourth on this serum's list, beside Tranexamic Acid.
Nicotinamide Mononucleotideactive
Nicotinamide Mononucleotide is a nucleotide built from vitamin B3 and a sugar phosphate. Korean formulas use it as a conditioning active, usually alongside niacinamide itself. The panel names it forty-sixth on this serum's list, beside Tranexamic Acid.
Nicotinamide Adenine Dinucleotideactive
Nicotinamide Adenine Dinucleotide, usually written NAD, is a coenzyme every living cell carries, built from vitamin B3. In a formula it is used as a conditioning active at very low levels. It is named forty-seventh on this serum's list, alongside Tranexamic 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 Tranexamic Acid and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, Tranexamic 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 Tranexamic Acid?
Niacinamide, Adenosine and Nicotinamide Mononucleotide. The order they are printed in on this serum's panel is the order on the box, so you can see where Tranexamic Acid sits relative to them. Further down the same panel: Nicotinamide Adenine Dinucleotide, Adenosine Triphosphate and Gluconolactone.

How to use
- Cleanse and tone, then apply this while the skin is still slightly damp so it spreads without dragging.
- Use one or two pumps for the whole face and press it in with flat palms rather than rubbing in circles.
- Wait until the surface feels tacky rather than wet, then put your moisturiser on top.
- Do not use it as your only layer on dry skin, since a light fluid left uncovered is the first thing to evaporate.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Tranexamic Acid on the list.
- Gluconolactone on this list makes this serum an exfoliating step, so do not stack it with another one on the same night.
