Science
Mechanism of Action
The extract operates through a high concentration of phytochemicals, specifically chlorogenic, caffeic, and ferulic acids, which neutralize reactive oxygen species (ROS). It further supports skin clarity by exhibiting modest tyrosinase inhibition to prevent uneven pigmentation, while its antimicrobial properties help maintain a balanced skin microbiome.
