Birch 70 Moisture Boosting Serum — 30ml

The serum version of the birch ritual: 70% Japanese white birch water, subacidic and featherlight, keeping pH balanced and moisture topped up.

THE RITUAL — After toner, before cream. Layer it under the Birch 70 cream for the full effect.

Why we chose it. The treat step of the Birch 70 ritual — made to layer under the cream. The two together are the Barrier Duo.
