Collection: Round Lab Birch Juice

Birch sap is what the whole line runs on, gathered in spring in the birch forests of Inje, before the leaves come out, through a small hole in the trunk. How much of it a product carries varies more than you might expect: the cream, toner and cleanser all state 10,000 ppm, while the sun stick holds 1,045 — nearly ten times less, because a stick is for topping protection up rather than for maximum hydration. The cleanser is slightly acidic, pH 5.0 to 6.0.
