Science
Mechanism of Action
The extract regulates the filaggrin (FLG) cycle, promoting its degradation into Natural Moisturizing Factors (NMFs) like Pyrrolidone Carboxylic Acid (PCA) for rapid hydration. Simultaneously, it stimulates new FLG synthesis to repair the skin barrier while utilizing its high flavonoid content (rutin and quercetin) to neutralize free radicals and suppress inflammatory cytokines like TNF-α.

Key findings
- 01 A 2% concentration demonstrated a 59.6% inhibition of UVB-induced redness, significantly outperforming tocopheryl acetate at 22%.
- 02 Application at 5% concentration yielded measurable, long-lasting hydration improvements across facial and body skin within 30 minutes of use.
- 03 In reconstructed epidermis models, a 3% concentration successfully increased filaggrin synthesis within a 24-hour period.

Dusting Analysis
While frequently listed in 'natural' formulas for marketing purposes at concentrations below 0.5%, the clinical data suggests that a minimum of 2% is required to achieve meaningful photoprotective and barrier-repair results.
