How it works
The Heartleaf 77 B3 Zinc Trouble Serum is a serum, used after toner and before moisturizer, morning and evening. The active it is built around is Exosomes, named thirtieth on its own ingredient list. The same list carries Niacinamide, Zinc PCA and Adenosine, so the active is not the only thing on it worth naming. How much of the Exosomes stays on the skin, and for how long, is decided by the serum format rather than by the list alone. Anua sells this Exosomes serum in Korea, and this is that version.

Key actives
Exosomesactive
Exosomes are the tiny membrane-bound packets cells release to carry molecules between them. In Korean formulas they are a recent conditioning ingredient, usually plant or ferment derived and declared at very low levels. 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 second on this serum's list, beside Exosomes.
Zinc PCAactive
Zinc PCA pairs zinc with the humectant PCA. It is used in oily and blemish-prone formulas for the look of shine and visible pores, and it hydrates at the same time. The panel names it tenth on this serum's list, beside Exosomes.
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 twentieth on this serum's list, alongside Exosomes.
Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named twenty-second on this serum's list, alongside Exosomes.
Anua Heartleaf 77 B3 Zinc Trouble Serum
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 Exosomes and not three changes at once.
What else is on the list besides Exosomes?
Niacinamide, Zinc PCA and Adenosine. The order they are printed in on this serum's panel is the order on the box, so you can see where Exosomes sits relative to them. Further down the same panel: Dipotassium Glycyrrhizate, Allantoin and Gluconolactone.

How to use
- Use the Heartleaf 77 B3 Zinc Trouble Serum after toner and before moisturizer, morning and evening.
- Three or four drops covers the whole face. Press it in with flat palms instead of rubbing it around.
- Toner first so the surface is damp, then this, then about a minute before your moisturizer goes over the top.
- Twice a day, every day. Do not stack it with a second serum of the same kind; two hydrating serums in one routine do the work of one.
Worth knowing
- Patch test this serum on a small area and wait a day before using it more widely, especially with Exosomes on the list.
- Citric Acid and Gluconolactone on this list makes this serum an exfoliating step, so do not stack it with another one on the same night.
