Science
Mechanism of Action
The extract operates via multiple biological pathways: it neutralizes oxidative stress by scavenging free radicals, inhibits tyrosinase to modulate melanin production, and suppresses degradative enzymes like collagenase, elastase, and matrix metalloprotein-1 (MMP-1) to preserve dermal structural integrity. Additionally, its antimicrobial properties help maintain a balanced skin microbiome.
Research
Clinical Evidence
High confidence0.03%
Key findings
- 01 Demonstrated significant enzymatic inhibition with an IC50 of 0.01813% for antityrosinase activity and 0.03264% for anti-MMP-1 activity.
- 02 Achieved half-maximal antioxidant scavenging (DPPH) at a precision concentration of 0.01235%.

Dusting Analysis
While many formulas include this extract at trace levels for marketing 'botanical' appeal, clinical data confirms that concentrations below 0.01% may fail to reach the IC50 threshold required for meaningful antioxidant or anti-aging enzymatic inhibition.
The Formula
Formulation
Stability
Aqueous extracts maximize phenolic and flavonoid recovery. Formulations should be maintained within a pH range of 3.5 to 7.0 to ensure constituent stability.
Synergies
- Vitamin C
- Carotenes
- Triterpenes
Conflicts
- High-concentration limonene/linalool sources (increased sensitization risk)
- EU-regulated furocoumarin limits in sun-care products
Safety
Safety Profile
Safe up to 8% in non-sensitizing formulations. Formulators must monitor the cumulative concentration of linalool and limonene hydroperoxides, which are potential sensitizers.
