Science
Mechanism of Action
It functions by inhibiting melanogenesis through tyrosinase and tyrosine kinase suppression, thereby regulating melanin distribution. Additionally, it bolsters skin barrier function via filaggrin and involucrin stimulation, providing antioxidant and anti-inflammatory protection.
