How it works
The ReDRN Exosome Ampoule is a 15ml ampoule, used after toner and before moisturizer, morning and evening. The active it is built around is Niacinamide, named seventh on its own ingredient list. The same list carries Sodium DNA, Allantoin and Adenosine, so the active is not the only thing on it worth naming. How much of the Niacinamide 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 Dr. nineteen sells in Korea, Niacinamide and all.

Key actives
Niacinamideactive
Niacinamide is vitamin B3, and it is the most studied active in Korean formulation. On this ampoule's own ingredient list it is named seventh.
Sodium DNAactive
Sodium DNA is the salt of DNA, in Korean skincare almost always salmon derived, and it is the ingredient behind the PDRN category. It is used as a humectant and for the look of tired skin; the fragments themselves are what the name PDRN refers to. The panel names it fifteenth on this ampoule's list, beside Niacinamide.
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. It is named nineteenth on this ampoule's list, alongside Niacinamide.
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-sixth on this ampoule's list, beside Niacinamide.
Retinolactive
Retinol is the alcohol form of vitamin A and the strongest retinoid available without a prescription. Skin converts it in two steps to retinoic acid, and it is used at night, at low percentages, for the look of fine lines and rough texture. It is named forty-fourth on this ampoule's list, alongside Niacinamide.
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 Niacinamide and not three changes at once.
Is this the Korean-market ampoule or a US version?
The Korean-market one, Niacinamide 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 Niacinamide?
Sodium DNA, Allantoin and Adenosine. The order they are printed in on this ampoule's panel is the order on the box, so you can see where Niacinamide sits relative to them. Further down the same panel: Retinol, Bifida Ferment Filtrate and Tocopherol.

How to use
- Use the ReDRN Exosome Ampoule after toner and before moisturizer, morning and evening.
- Apply a moderate amount onto the skin and gently pat for better absorption.
- 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 Niacinamide on the list.
- Retinol is on this list, so keep this ampoule to the evening and build the nights up slowly rather than starting nightly.

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.
