Science
Mechanism of Action
This extract is abundantly rich in polyphenolic compounds, including various flavonoids (such as orientin, eriocitrin, and rutin), anthocyanins, lignans, and protocatechuic acid (PCA). These potent compounds collectively confer its antioxidant properties by efficiently scavenging free radicals, thereby protecting the skin from oxidative stress and environmental aggressors. Furthermore, its demonstrated antimicrobial activity helps maintain a healthy skin flora, while its anti-inflammatory and soothing properties work to calm irritation and reduce redness. The extract also functions as a skin conditioning agent, enhancing skin hydration.

The Formula
Formulation
Stability
The extract's color-imparting compounds, specifically anthocyanins and flavonoids, are pH-sensitive. They exhibit distinct color changes across various pH ranges (e.g., 8.9-4.12, 8.2-4.34, 9.1-5.35, 8.1-5.12), requiring careful pH management during formulation to ensure desired color stability.
Safety
Safety Profile
While formal safety assessments by major regulatory bodies like CIR, SCCS, or FDA are currently unavailable, general industry sources indicate this extract is 'generally non-irritating' and has 'no penalty' in safety categories by INCI Beauty. Research has noted 'high cutaneous toxicity' for an isolated constituent (Jacaranone), but this finding is not considered directly applicable to the extract's typical use in cosmetic formulations.
