Science
Mechanism of Action
This extract operates through several key mechanisms: its rich content of flavonoids and phenolic acids provides robust antioxidant defense, neutralizing free radicals to prevent oxidative stress. It exhibits anti-inflammatory action by significantly inhibiting COX-1 and COX-2 enzymes, thereby reducing redness and irritation. Furthermore, it promotes localized blood circulation, aids in moisture retention, helps restore the skin's natural protective barrier, and provides antibacterial activity, which can be beneficial against infections and acne-causing bacteria.

Stability
Optimal stability and viscosity for topical applications have been observed at a precise pH of 7.4. The inclusion of Disodium EDTA within neutralizing solutions further enhances its stability, suggesting a potential benefit from chelating agents in formulation.
Conflicts
- While no specific incompatibilities are listed, there is a noted likelihood of irritation when combined with other potentially problematic ingredients, suggesting caution during formulation development.
Safety
Safety Profile
Formal safety assessments by major regulatory bodies such as CIR, SCCS, or FDA are currently lacking. Dermal toxicity remains undetermined. While general toxicity studies in animal models suggest good safety at lower concentrations, there is a noted likelihood of irritation, particularly when combined with other potentially problematic ingredients, as highlighted by expert opinions.
