The star of this lotion isn't water—it's birch sap, packed with amino acids and antioxidants that hydrate like a drink of water for your skin, minus the heaviness.
Birch Sap (70%)
Lightweight hydration that calms redness and replenishes without clogging pores.
Panthenol
Strengthens skin barrier and soothes post-exfoliation sensitivity.
Allantoin
Gentle healer that softens and reduces irritation.
"Birch sap is like nature's electrolyte drink for skin—it delivers hydration where oily complexions need it most, without the grease."
