ANUA Birch 70% Moisture Boosting Serum 30ml

ANUA Birch 70% Moisture Boosting Serum 30ml leans on a 70% concentration of birch sap, known scientifically as Betula Platyphylla Japonica Juice, a natural moisture reservoir traditionally valued for its amino acid and mineral content. Trehalose and panthenol add further hydration, while a gentle PHA, gluconolactone, supports smoother texture without the irritation stronger acids can cause.
