Science
Mechanism of Action
Works by inhibiting tyrosinase enzyme activity to reduce melanin production while simultaneously scavenging reactive oxygen species and boosting endogenous antioxidant enzymes like SOD and GPX. Additionally modulates inflammatory pathways by suppressing IL-6 and TNF-alpha cytokines through NF-kB pathway regulation.

Dusting Analysis
Given the demonstrated efficacy at 0.1-0.5% concentrations and potent activity at low doses, formulations below 0.05% may indicate dusting rather than therapeutic intent.
The Formula
Formulation
Stability
Maintains stability in aqueous systems but polyphenolic components degrade under UV exposure and elevated temperatures. Commonly stabilized with propanediol or glycerin.
