Science
Mechanism of Action
Functions as a multi-pathway brightening agent by inhibiting tyrosinase enzyme activity to reduce melanin production by 17-36%, while simultaneously neutralizing free radicals through Nrf2 pathway activation and chelating metal cofactors essential for pigment formation
Research
Clinical Evidence
High confidence3%
Key findings
- 01 Clinical trial with 15 women aged 45-76 showed visible age spot reduction and improved skin evenness at 3% concentration after 4 weeks twice-daily application
- 02 In vitro studies confirmed 17-36% melanin biosynthesis reduction through tyrosinase inhibition at 1-3% concentrations
