Science

Mechanism of Action

This extract operates through multiple pathways to enhance skin vitality. It provides robust antioxidant defense by shielding the skin from free radicals and environmental aggressors. By inhibiting inflammatory pathways and possessing anti-histaminic properties, it effectively mitigates skin irritation and redness. It actively supports skin regeneration, promoting healthy cellular turnover and fortifying the skin barrier. Furthermore, it stimulates fibroblast proliferation, aids re-epithelialization, and facilitates extracellular matrix maturation, thereby accelerating wound healing. Its inherent antifungal and antimicrobial actions contribute to overall skin health, while its conditioning effects visibly improve skin texture and suppleness.
