Key actives
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 the entry this serum is named after, and the list carries it.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. The panel names it eighteenth on this serum's list, beside 3-O-Ethyl Ascorbic Acid.
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 nineteenth on this serum's list, beside 3-O-Ethyl Ascorbic Acid.
Madecassosideactive
Madecassoside is the centella triterpene most associated with the look of redness, and the one brands lead with in cica products. It is water soluble and stable, so it appears in essences as readily as in creams. It is named twenty-eighth on this serum's list, alongside 3-O-Ethyl Ascorbic Acid.
Proteaseactive
Protease is an enzyme that breaks down protein. In a cleanser or peel it loosens the protein bonds holding dead surface cells together, which is a gentler route to smoothness than an acid or a scrub. It is named thirtieth on this serum's list, alongside 3-O-Ethyl Ascorbic Acid.
How to use
- Apply two to three drops after toner or essence and before your moisturizer, once or twice a day. Press it into the face and neck with clean palms rather than rubbing, and give it a minute to absorb before layering a cream on top.
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 3-O-Ethyl Ascorbic Acid and not three changes at once.
Is this the Korean-market serum or a US version?
The Korean-market one, 3-O-Ethyl 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 3-O-Ethyl Ascorbic Acid?
Niacinamide, Allantoin and Madecassoside. The order they are printed in on this serum's panel is the order on the box, so you can see where 3-O-Ethyl Ascorbic Acid sits relative to them. Further down the same panel: Protease, Gluconolactone and Lactobacillus Ferment Lysate.

How it works
The Green Tea Enzyme Vitamin C Brightening Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The antioxidant it is built around is 3-O-Ethyl Ascorbic Acid, named fifth on its own ingredient list. The same list carries Niacinamide, Allantoin and Madecassoside, so the antioxidant is not the only thing on it worth naming. How much of the 3-O-Ethyl 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 innisfree sells in Korea, 3-O-Ethyl Ascorbic Acid and all.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with 3-O-Ethyl Ascorbic 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.
