Science
Mechanism of Action
This extract executes its effects through a multi-faceted mechanism. It robustly scavenges reactive oxygen species (ROS), thereby reducing oxidative stress, and activates the Nrf2/HO-1 signaling pathway while concurrently downregulating the MAPK and NF-κB pathways to mitigate inflammatory responses. Its anti-aging action involves shielding keratinocytes from UVB/H2O2-induced oxidative damage, enhancing type 1 procollagen gene activity, and decreasing expression of matrix metalloproteinases (MMPs), COX-2, IL-6, and hyaluronidase. For antimelanogenic benefits, it precisely reduces melanin production, lowers tyrosinase and microphthalmia-associated transcription factor (MITF) protein levels, and diminishes phosphorylation of p38 and JNK. Additionally, the extract induces autophagy, promoting cellular renewal by increasing GFP-LC3B expression and decreasing melanin content in melanoma cells.
