Science
Mechanism of Action
Selectively inhibits tyrosinase enzyme activity to regulate melanin production, while functioning as an anti-irritant that dampens inflammatory responses to environmental stressors including UV exposure, visible light, and pollutants
Research
Clinical Evidence
High confidence0.5%
Key findings
- 01 Human cell culture and volunteer studies at 0.1-1.0% demonstrated significant tyrosinase inhibition with measurable melanin reduction and visible brightening effects
- 02 Clinical trials at 0.5% in combination with niacinamide showed proven reduction in dark spot intensity and size through targeted oxidative stress mitigation
Transparency
Dusting Analysis
Effective concentrations start at 0.1%, making sub-threshold amounts functionally inactive for brightening benefits
