Science
Mechanism of Action
This extract acts as a potent antioxidant by scavenging free radicals and upregulating the skin's endogenous antioxidant enzyme expression. Its anti-aging efficacy stems from inhibiting matrix metalloproteinase (MMP-2, MMP-9, and MMP-3) activity via the MAPK signaling pathway, thereby preventing collagen degradation induced by oxidative damage, such as from hydrogen peroxide (H2O2).

Key findings
- 01 In human dermal fibroblasts, Pourthiaea Villosa Leaf Extract (PVDE) demonstrated significant antioxidant effects, including ABTS and DPPH radical scavenging activity, and an increase in antioxidant enzyme expressions.
- 02 PVDE exhibited anti-aging effects by effectively blocking hydrogen peroxide (H2O2)-induced matrix metalloproteinase (MMP-2, MMP-9, and MMP-3) activity through MAPK signaling pathways in human dermal fibroblasts, thus protecting the collagen matrix from degradation.
