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. This is the Original Korean Formula, the serum Anua sells in Korea, Allantoin and all.

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. The panel names it twenty-eighth on this serum's list, beside 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. It is named thirty-first on this serum's list, alongside 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.
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.
Is this the Korean-market serum or a US version?
The Korean-market one, Allantoin and all. We match this serum 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 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 it after your toner, morning or night, while the skin is still slightly damp from that step.
- Take a few drops and press it over the whole face and neck rather than rubbing it into one area.
- Follow with a moisturiser, since a serum on its own has nothing holding it in place.
- Do not apply it to dry skin, because you will end up using twice as much for a thinner layer.
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.

What professionals say
What professionals say
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 contains liquiritin, an active compound that helps to disperse and remove existing melanin in the skin.

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.
