Science
Mechanism of Action
Daphne Feddei Leaf Extract functions as a robust antioxidant, actively inhibiting oxidation reactions and safeguarding formula integrity against deterioration caused by oxygen. In vitro studies confirm its significant scavenging capacity against free radicals and demonstrate an ability to inhibit nitric oxide production, thereby exerting anti-inflammatory effects. The broader *Daphne* genus is rich in bioactive compounds such as flavonoids, lignans, and terpenoids, which collectively contribute to antioxidant, anti-inflammatory, analgesic, and antimicrobial activities. While specific to a related species, *Daphne odora*, cellular assays have indicated potential for enhanced hydration, improved moisture retention, sebum regulation through 5αR1 induction, and accelerated epidermal healing rates, suggesting broader benefits within the genus.
