Science
Mechanism of Action
The extract operates through a high-affinity radical scavenging system, utilizing its phenolic fractions to neutralize reactive oxygen species (ROS). It further mitigates skin aging by suppressing pro-inflammatory cytokines such as IL-6 and TNF-α, while simultaneously inhibiting tyrosinase and elastase enzymes to preserve structural proteins and even skin tone.

Clinical Evidence
Medium confidence2.5%
Key findings
- 01 In vitro analysis demonstrates significant radical scavenging with an IC50 as low as 1.88 µg/ml (ABTS) and 5.72 µg/ml (DPPH).
- 02 Formulation data indicates effective tyrosinase inhibition and fibroblast anti-senescence activity at concentrations between 0.5% and 5%.
Transparency
Dusting Analysis
Due to its complex phytochemical profile, it is often included at negligible levels (<0.1%) for label claims. To achieve measurable anti-aging and brightening effects, a minimum threshold of 0.5% is recommended.
