DENDROPANAX MORBIFERUS STEM SAP.

The mechanism of Dendropanax Morbiferus Stem Sap on skin is rooted in its diverse array of bioactive constituents, including polyphenols, flavonoids, terpenoids, and polyacetylenes. It exhibits significant antioxidant activity by directly scavenging free radicals and upregulating endogenous antioxidant enzymes such as superoxide dismutase (SOD) and catalase (CAT), thereby minimizing oxidative stress and lipid peroxidation. For inflammation, it intervenes by inhibiting pro-inflammatory cytokines (e.g., TNF-α, IL-6), modulating NF-κB/MAPK pathways, and reducing nitric oxide production, which collectively mitigates inflammatory skin responses. Its skin brightening effects are achieved through the inhibition of tyrosinase activity and melanin synthesis, alongside the downregulation of key melanogenesis-related proteins like MITF, TRP-1, and TRP-2. Furthermore, the sap demonstrates anti-aging properties by significantly inhibiting both collagenase and elastase enzymes, crucial for maintaining skin structural integrity. Additional benefits include antimicrobial efficacy against various pathogens and contributions to skin hydration.
