anua Birch 70 Moisture Boosting Serum 30ml

There's something unexpected about this serum: its base isn't plain water, but 70% Japanese white birch juice. That single detail changes everything — the texture, the way it hydrates, and how readily the skin takes it in. Every other ingredient follows the same thinking: each one is there for a reason, nothing is just padding.

Texture and actives — The serum is built around a slightly acidic formula — its pH is calibrated to sit close to the skin's own, which helps avoid any disruption at the moment of application. Betula Platyphylla Japonica Juice (Japanese white birch juice) makes up 70% of the base and helps the skin hold onto moisture. Layered on top of that is a system of ten forms of hyaluronic acid: Sodium Hyaluronate, Hydroxypropyltrimonium Hyaluronate, Sodium Acetylated Hyaluronate, Hydrolyzed Hyaluronic Acid, Hyaluronic Acid, Sodium Hyaluronate Crosspolymer, Hydrolyzed Sodium Hyaluronate, Potassium Hyaluronate — molecules of varying molecular weights that work at different depths within the skin. Panthenol supports the skin barrier. Rounding things out is what the brand calls the ABC Complex: Allantoin (soothing), Betaine (moisture balance) and Cucumis Sativus Fruit Extract (cucumber extract, for sensitive skin). Vegan formula, not tested on animals.

In your routine — Morning or evening, after cleansing and before moisturiser. Use a modest amount — the serum spreads easily across the whole face, then gently pat it in with your fingertips to help absorption. It sinks in without leaving any residue, which makes it easy to layer — under sunscreen in the morning or a richer treatment at night.
