Used as a natural antioxidant in cosmetic formulations to protect skin from oxidative stress and UV-induced damage. It also inhibits tyrosinase activity, promoting even skin tone and reducing hyperpigmentation such as freckles, age spots, and melasma. Employed in herbal supplements for its anti-inflammatory, immune-boosting, and potential anticancer properties. Acts as a bioactive marker in quality control of plant extracts, particularly in flavonoid-rich botanicals. Applied in research settings to study flavonoid metabolism and structure-activity relationships in polyphenolic compounds.
