Science
Mechanism of Action
Functions through multiple pathways including peroxidase enzyme activity to neutralize reactive oxygen species, downregulation of inflammatory gene expression, and inhibition of lipid accumulation in skin cells. The concentrated glucosinolates and phenolic compounds provide enhanced UV-protective benefits by strengthening internal antioxidant defense systems.

Clinical Evidence
High confidence2%
Key findings
- 01 ROS generation inhibition and anti-inflammatory activity at 1.0-3.0% concentration
- 02 Preadipocyte proliferation reduction and lipid accumulation inhibition at 25-100 ng/ml
- 03 Enhanced ABTS radical scavenging ability under UVB exposure conditions
Transparency
Dusting Analysis
Given the clinically effective range of 1.0-3.0%, concentrations below 0.1% would likely provide minimal benefit and could indicate dusting practices.
