What it is
Betula Alba Leaf Extract is obtained from the leaves of the white or silver birch tree and contains flavonoids and other plant polyphenols. It is used in skincare as a plant-derived conditioning ingredient often associated with a soothing feel. In sunscreens it is included as a minor botanical component rather than as a functional UV ingredient.
Safety & warnings
Generally well tolerated when used topically at typical low cosmetic levels. Birch-derived materials can occasionally be relevant for individuals with known birch-pollen allergies, and as with any plant extract composition varies by source.
Origin & sourcing
Plant-derived, obtained from the leaves of Betula alba (white birch), a tree common across Europe and northern Asia.
Questions everyone asks
Is this the same as birch sap or bark?
No. This ingredient is specifically a leaf extract of white birch, which differs from birch sap, juice, or bark-derived materials.
What does it do in a formula?
It acts as a botanical skin-conditioning and antioxidant additive, not as a sunscreen active.
