Betula Alba Bark/Leaf Extract

Betula alba (silver birch) bark and leaf extract is derived from the birch tree native to northern Europe. The extract contains compounds including betulin, flavonoids, and tannins, which give it astringent and mild antimicrobial properties.In skincare formulations, this ingredient is primarily used for its toning and cleansing action. It has a long history in traditional herbalism and folk skincare, though its use in modern cosmetics remains relatively modest.

Betula alba extract works primarily through its tannin content, which binds to proteins in the outer layers of skin, creating a mild tightening or astringent effect. This can temporarily reduce the appearance of pores and help blot excess oil.The flavonoids present may also offer antioxidant support, though the degree to which these compounds penetrate and benefit deeper skin layers remains unclear. The extract's traditional use as a skin tonic suggests cumulative mild benefits with regular application, though more modern clinical data is limited.

Birch extract is typically found in cleansers, toners, and lightweight serums. For best results, use consistently as part of your routine—astringent benefits tend to build over time rather than offer immediate results. It works well in combination with hydrating or barrier-supporting ingredients to avoid any drying effects, particularly if you have sensitive or dry skin.

Generally well-tolerated and considered safe for use in cosmetics. Individuals with known birch pollen allergy may wish to patch-test first, though topical sensitisation is uncommon.
