How it works
The Birch Moisture Boosting Serum is a 30ml serum, used after toner and before moisturizer, morning and evening. The active it is built around is Allantoin, named fifteenth on its own ingredient list. The same list carries Dipotassium Glycyrrhizate, Gluconolactone and Tocopherol, so the active is not the only thing on it worth naming. How much of the Allantoin stays on the skin, and for how long, is decided by the serum format rather than by the list alone. Anua sells this Allantoin serum in Korea, and this is that version.

Key actives
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. On this serum's own ingredient list it is named fifteenth.
Dipotassium Glycyrrhizateactive
Dipotassium Glycyrrhizate is a water-soluble salt derived from licorice root. It is named twenty-eighth on this serum's list, alongside Allantoin.
Gluconolactoneexfoliant
Gluconolactone is a PHA, the gentlest exfoliant class. The panel names it twenty-sixth on this serum's list, beside Allantoin.
Tocopherolantioxidant
Tocopherol is vitamin E. It is an oil-soluble antioxidant that protects the oils in a formula from going rancid and works on skin as an emollient, and it is regularly paired with vitamin C because each keeps the other going for longer. The panel names it thirty-first on this serum's list, beside Allantoin.
Biosaccharide Gum-1polysaccharide
Biosaccharide Gum-1 is a fermentation-derived sugar polymer that binds to skin and holds a moisture film in place. It gives a silky, non-tacky feel. It is named twenty-seventh on this serum's list, alongside Allantoin.
Anua Birch Moisture Boosting 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 Allantoin and not three changes at once.
What else is on the list besides Allantoin?
Dipotassium Glycyrrhizate, Gluconolactone and Tocopherol. The order they are printed in on this serum's panel is the order on the box, so you can see where Allantoin sits relative to them. Further down the same panel: Biosaccharide Gum-1, Cucumis Sativus (Cucumber) Fruit Extract and Gardenia Florida Fruit Extract.

How to use
- Use the Birch Moisture Boosting 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 Allantoin 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.

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.

This means that gluconolactone acts as an exfoliating acid, but also as a moisturizer. It has moisturizing, soothing, and lightening properties, working well on dry skin.
