What it is
Berberis Vulgaris Root Extract is derived from the roots of the barberry shrub, which are naturally rich in the yellow alkaloid berberine and related compounds. In formulations it is used as a plant-based conditioning and antioxidant ingredient. It appears in sunscreens as a minor botanical addition rather than as a sun-protective active.
Safety & warnings
Used topically at low levels, the root extract is generally well tolerated. Composition can vary with source and extraction, and as with any botanical, occasional sensitivity is possible in predisposed individuals.
Origin & sourcing
Plant-derived, obtained from the roots of Berberis vulgaris (common barberry), a thorny deciduous shrub native to Europe and parts of Asia.
