Science
Mechanism of Action
Hosta Longipes Extract exerts its effects by inhibiting nitric oxide (NO) production, thereby reducing inflammatory responses in the skin. It also provides antioxidant protection, combating oxidative stress. Furthermore, it actively contributes to skin brightening by blocking melanocortin 1 receptor signaling, which is crucial in melanin synthesis. Its efficacy is attributed to key active compounds such as steroidal saponins, flavonoid glycosides (including longipenane and its derivatives), and essential fatty acids like linolenic and linoleic acid.
