Science
Mechanism of Action
This extract operates through several key mechanisms to benefit skin health. Primarily, it functions as a potent antioxidant, effectively neutralizing free radicals and mitigating oxidative stress induced by environmental aggressors like pollution and UV radiation. For skin brightening, it precisely inhibits tyrosinase, the crucial enzyme in melanin production, which aids in fading existing hyperpigmentation and preventing the formation of new dark spots. Additionally, it exhibits anti-inflammatory properties, offering a calming effect on irritated skin, and may contribute to anti-aging by protecting skin cells from UV-induced damage and potentially supporting the synthesis of collagen and elastin, thereby diminishing the appearance of fine lines and wrinkles. It can also support skin barrier function, promote hydration, and has demonstrated antimicrobial effects.

Key findings
- 01 Exhibited significant 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity with an IC50 of 1.6 µg/mL in vitro, indicating robust antioxidant effects.
- 02 Inhibited H2O2-induced apoptosis and notably enhanced the viability of Chinese hamster lung fibroblast (V79-4) cells in vitro.
- 03 Dose-dependently augmented the activities of key endogenous antioxidant enzymes: superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) in V79-4 cells.
- 04 Demonstrated potent inhibitory activity against tyrosinase, the enzyme central to melanin synthesis, and effectively reduced melanin content in B16F10 melanoma cells.
- 05 Cosmetic compositions containing this extract, within a range of 0.0001-10 wt.%, are effective in safeguarding the skin from environmental stresses.
