Science
Mechanism of Action
Works through multiple pathways: neutralizes free radicals via high concentrations of antioxidant compounds, reduces inflammation by suppressing nitric oxide production and downregulating pro-inflammatory cytokines TNF-alpha and IL-6, and provides DNA repair support through sulforaphane content while inhibiting tyrosinase for potential brightening effects.

Key findings
- 01 6% concentration significantly reduced inflammatory and non-inflammatory acne lesions over 30 days (International Journal of Herbal Medicine, 2023)
- 02 Topical application effectively inhibited epidermal hyperplasia and immune cell infiltration in contact dermatitis models (Pharmacognosy Magazine, 2018)
Transparency
Dusting Analysis
Given the proven efficacy at 1-6% concentrations and food-grade safety profile, concentrations below 0.5% would likely provide minimal therapeutic benefit beyond marketing claims.
