Science
Mechanism of Action
This extract operates through a multifaceted mechanism, primarily acting as an antioxidant by both chelating ferrous ions and scavenging DPPH radicals, thereby mitigating oxidative stress. Its brightening effect stems from direct inhibition of tyrosinase activity, a key enzyme in melanin production. Furthermore, it actively enhances the skin's inherent moisture-retaining capabilities and supports the skin's natural repair processes, collectively contributing to anti-aging benefits.
