How it works
The Onion Newpair Booster Shot 2000 is a 50ml serum, used after toner and before moisturizer, morning and evening. The plant extract it is built around is Allium Cepa (Onion) Bulb Extract, named eighth on its own ingredient list. The same list carries Niacinamide, Hydrolyzed Sponge and Adenosine, so the plant extract is not the only thing on it worth naming. How much of the Allium Cepa (Onion) Bulb Extract stays on the skin, and for how long, is decided by the serum format rather than by the list alone. Isntree sells this Allium Cepa (Onion) Bulb Extract serum in Korea, and this is that version.

Key actives
Allium Cepa (Onion) Bulb Extractplant extract
Onion Bulb Extract carries quercetin and sulphur compounds. Korean formulas use it for the look of blemish marks and uneven tone, and it is the namesake ingredient of the onion skincare line. The name on the box points at it, and it is named eighth 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 Allium Cepa (Onion) Bulb Extract.
Hydrolyzed Spongeactive
Hydrolyzed Sponge is processed freshwater sponge, which carries fine silica spicules. In a formula it works as a mild physical exfoliant. It is named twentieth on this serum's list, alongside Allium Cepa (Onion) Bulb 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. It is named twenty-fourth on this serum's list, alongside Allium Cepa (Onion) Bulb Extract.
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. The panel names it thirty-eighth on this serum's list, beside Allium Cepa (Onion) Bulb Extract.
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 Allium Cepa (Onion) Bulb Extract and not three changes at once.
What else is on the list besides Allium Cepa (Onion) Bulb Extract?
Niacinamide, Hydrolyzed Sponge and Adenosine. The order they are printed in on this serum's panel is the order on the box, so you can see where Allium Cepa (Onion) Bulb Extract sits relative to them. Further down the same panel: Madecassoside, Allantoin and Resveratrol.
