Science
Mechanism of Action
This extract's beneficial effects stem from its diverse flavonoid composition, including polymethoxyflavones, which function as potent antioxidants by neutralizing free radicals. Furthermore, select constituents have demonstrated moderate in vitro tyrosinase inhibitory activity, indicating a potential mechanism to reduce melanin synthesis and contribute to skin brightening.
