Coptis Japonica Root Extract

A traditional East Asian medicinal extract containing berberine and other alkaloids, used in cosmetics for antimicrobial and antioxidant claims. Modern cosmetic safety data is limited; it is generally reported as well tolerated, though patch testing is advisable for those with a history of contact sensitivity to botanicals.

Cosmetic information for general education, not medical advice. A verdict is a reading of the published evidence, never a guarantee for your skin: any ingredient can irritate someone, so patch test new products and see a professional if you react. Concern is graded on cited evidence, never on hazard-score lists. See how we score.
