Science

This botanical extract operates on multiple dermal pathways. In vitro studies indicate its antimicrobial action through the disruption of bacterial quorum sensing and antifungal activity against specific species, such as Aspergillus spp. Bioactive compounds like flavonoids, polyphenols, and essential oils contribute to its antioxidant capacity and direct antimicrobial effects. Furthermore, tannins within the extract provide astringent properties, while quercetin offers significant anti-inflammatory benefits, promoting a soothed skin environment.
