Science
Mechanism of Action
Functions through four primary biological actions: inhibiting NF-κB hypertranscription to prevent collagen degradation, acting as a phytoestrogen to stimulate dermal density, providing antioxidant protection via tectorigenin isoflavones, and modulating androgen-related pathways to suppress excessive sebum synthesis.

Key findings
- 01 A 5% concentration demonstrated a 16.2% improvement in skin lifting and a 15.5% enhancement in tone uniformity.
- 02 At 3%, the extract successfully inhibited NF-κB pathways responsible for photo-aging and collagen fiber breakdown.
- 03 Inclusion at 1% showed significant anti-sebum activity by modulating testosterone-induced lipid production in human sebocytes.

Dusting Analysis
While many formulas include this ingredient for label appeal at negligible levels, clinical data suggests a minimum of 1% is required for sebum control and a full 5% for measurable lifting and elasticity benefits.
The Formula
Formulation
Stability
Thermally stable up to 90°C. Maintaining a pH below 8.0 is critical to prevent color darkening and loss of absorbance integrity.
Synergies
