DENDROPANAX MORBIFERUS ADVENTITIOUS ROOT EXTRACT.

This extract exerts its beneficial effects through several distinct mechanisms within the skin. It functions as a potent antioxidant by effectively scavenging reactive oxygen species (ROS), thereby mitigating cellular oxidative stress and encouraging healthy cell proliferation. For its anti-hyperpigmentation and brightening effects, it inhibits tyrosinase expression and reduces melanin synthesis, while also modulating melanin transfer to keratinocytes. Key constituents like Viscumneoside III contribute to this tyrosinase inhibition, along with the downregulation of critical melanogenesis pathways including cAMP, PKA/CREB, p38 MAPK, MITF, TRP-1, and TRP-2. Furthermore, it demonstrates anti-inflammatory properties by suppressing the expression of interleukin markers (ILs), diminishing nitric oxide (NO) production, and inhibiting the JAK2/STAT pathway, which is crucial for reducing skin inflammation, including dermatitis. In terms of anti-aging and anti-wrinkle benefits, it stimulates collagen synthesis and inhibits collagenase (MMP-1) and elastase, enzymes responsible for collagen degradation, thus enhancing skin elasticity. The extract also exhibits antimicrobial activity against common skin bacteria such as Staphylococcus epidermidis and Staphylococcus aureus, and contributes to skin hydration.
