How it works
The Onion Newpair B5 Ampoule is a 50ml ampoule, used after toner and before moisturizer, morning and evening. The plant extract it is built around is Allium Cepa (Onion) Bulb Extract, named first on its own ingredient list. The same list carries Niacinamide, Allantoin and Caffeine, 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 ampoule format rather than by the list alone. This is the Original Korean Formula, the ampoule Isntree sells in Korea, Allium Cepa (Onion) Bulb Extract and all.

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. It is the entry this ampoule is named after, and the list carries it.
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. It is named fourth on this ampoule's list, alongside Allium Cepa (Onion) Bulb Extract.
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 twelfth on this ampoule's list, beside Allium Cepa (Onion) Bulb Extract.
Caffeineactive
Caffeine constricts small blood vessels near the surface, which is why eye products use it for the look of puffiness and shadow. It is water soluble and works only while it is on the skin. The panel names it fifteenth on this ampoule's list, beside Allium Cepa (Onion) Bulb Extract.
Acetyl Glucosamineactive
Acetyl Glucosamine is the sugar unit hyaluronic acid is built from. It is used as a humectant and, at higher levels, for the look of uneven tone, often paired with niacinamide. It is named sixteenth on this ampoule's list, alongside Allium Cepa (Onion) Bulb Extract.
Isntree Onion Newpair B5 Ampoule
Where does this ampoule go in my routine?
After toner and before moisturizer, morning and evening. Anything thinner than an ampoule 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.
Is this the Korean-market ampoule or a US version?
The Korean-market one, Allium Cepa (Onion) Bulb Extract and all. We match this ampoule 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 Allium Cepa (Onion) Bulb Extract?
Niacinamide, Allantoin and Caffeine. The order they are printed in on this ampoule'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: Acetyl Glucosamine, Adenosine and Tranexamic Acid.

How to use
- Use the Onion Newpair B5 Ampoule after toner and before moisturizer, morning and evening.
- Half a dropper, or two or three drops, is the amount for a whole face. Press it in rather than spreading it thin.
- It sits between the toner and the moisturizer, and it is the layer most worth leaving alone for a minute before anything covers it.
- Twice a day, every day. Do not use it as a spot application on one area; an ampoule is a routine step, not a targeted dose.
Worth knowing
- Patch test this ampoule on a small area and wait a day before using it more widely, especially with Allium Cepa (Onion) Bulb Extract on the list.
- Introduce this ampoule on its own for the first week, so anything your skin does is traceable to the Allium Cepa (Onion) Bulb Extract rather than to three changes at once.

What skin-care professionals say about the key actives in this formula, quoted from the medical sources linked beside each.
Allantoin can tone down the dryness of the individual cells. It increases the water content of the skin, which means it helps to hydrate and moisturize.
Wilma Bergfeld, MDDermatologist, Cleveland Clinic It has also been proven that caffeine stimulates lipolysis, which Lupo et al postulated may contribute to improvements in lower eyelid sagging and puffiness.

Niacinamide helps reduce the appearance of pores in a few ways. By strengthening the skin barrier and improving elasticity, pores appear less noticeable and more even.
