Science
Mechanism of Action
The ingredient operates through several synergistic pathways. Grifola Frondosa contributes to skin brightening by inhibiting tyrosinase, thereby reducing melanin formation. It also exhibits anti-inflammatory actions by modulating inflammatory cytokines and chemokines, potentially through p38 and ERK MAPK signaling pathways, offering relief for inflammatory conditions. Both Grifola Frondosa and Ilex Paraguariensis provide robust antioxidant defense, neutralizing free radicals with polyphenols, flavonoids (e.g., quercetin, rutin), and xanthines. Ilex Paraguariensis further supports anti-aging by preventing skin epithelium protein damage and offers skin conditioning, potentially forming a protective layer. Additionally, Ilex Paraguariensis extracts possess antimicrobial and antifungal properties, including activity against *Malassezia furfur*. Fermentation concentrates and optimizes these compounds, enhancing their effectiveness and skin penetration.
