Science
Mechanism of Action
This extract operates through a four-pronged approach: it inhibits the NF-κB signaling pathway to quell inflammatory responses, downregulates tyrosinase activity to prevent hyperpigmentation, neutralizes reactive oxygen species (ROS) via its high flavonoid content, and boosts Natural Moisturizing Factors (NMF) to stabilize the lipid barrier.

Clinical Evidence
High confidence0.2%
Key findings
- 01 In DPPH assays, a 0.2% concentration exhibited antioxidant properties comparable to pure Vitamin C (L-Ascorbic Acid).
- 02 Concentrations ranging from 0.05% to 0.5% reduced inflammatory markers NO and PGE2 by up to 60% and 23% in cell models.
- 03 At 0.02%, the extract was shown to effectively modulate T-cell activity, indicating high efficacy in anti-allergic applications.
Transparency
Dusting Analysis
Because it is effective at very low concentrations (as low as 0.02%), many mass-market brands include it at 'trace' levels below 0.01% for marketing purposes. For true therapeutic benefits, particularly for soothing and antioxidant protection, concentrations should meet or exceed 0.05%.
The Formula
