Science
Mechanism of Action
Activates the NRF2 cellular defense pathway, upregulating key antioxidant enzymes including HO-1 and NQO1 to create a biological shield against environmental oxidative stress. Simultaneously inhibits tyrosinase enzyme activity to reduce melanin synthesis for brightening effects, while suppressing inflammatory cascades through NF-κB and MAPK pathway modulation.
Research
Clinical Evidence
High confidence1%
Key findings
- 01 Demonstrated potent antityrosinase activity with IC50 of 38.17 mg/L for hyperpigmentation reduction (0.1-2.0%)
- 02 Significantly reduced UVB-induced oxidative damage and inflammatory markers TNF-α and NO in dermal cells (0.5-2.0%)
Transparency
Dusting Analysis
Given the demonstrated efficacy starting at 0.1% concentration, formulations below 0.05% would likely provide minimal functional benefit and constitute dusting.
The Formula
Formulation
Stability
Most stable in hydroglycolic or aqueous solutions; heat-sensitive and should be incorporated during cooling phase of emulsions to preserve bioactivity
Synergies
- Vitamin C
