Science
Mechanism of Action
This extract operates through several biological pathways: it neutralizes oxidative stress via high-capacity radical scavenging and suppresses inflammatory markers like nitric oxide. On a structural level, it inhibits collagenase and hyaluronidase enzymes to prevent the breakdown of the skin's support matrix, while simultaneously acting as a tyrosinase inhibitor to regulate melanin production and brighten the complexion.

Clinical Evidence
Medium confidence5%
Key findings
- 01 Observed radical scavenging activity reaching 90.38% in standardized 70% ethanol peel extracts.
- 02 Achieved an IC50 for collagenase inhibition at 26.045 μg/mL, indicating high potency for anti-aging applications.
- 03 Demonstrated significant anti-acne and antioxidant synergy in 20% gel formulations during standardized testing.
Transparency
Dusting Analysis
While it shows bioactivity at very low concentrations (μg/mL range), many commercial products include it at 'label-only' levels below 0.1% to avoid the complexities of phototoxicity management while claiming its botanical benefits.
The Formula
Formulation
Stability
The extract is naturally acidic; increasing concentrations can significantly lower the final formulation pH and decrease the viscosity of gel-based systems.
Synergies
- Broad-spectrum sunscreens
- Vitamin C
- Niacinamide
Conflicts
- High-level photosensitizers
- pH-sensitive thickeners
Safety
Safety Profile
Safety is contingent on the concentration of 5-methoxypsoralen (5-MOP), which must not exceed 15 ppm in leave-on products due to phototoxicity risks. Formulations must be tested to ensure they are non-sensitizing.
