Gynostemma pentaphyllum-derived extracellular vesicles alleviate skin aging by destabilizing STING

-derived extracellular vesicles (GPEVs), demonstrating their unprecedented efficacy in alleviating UVB-induced skin aging. Specifically, GPEVs restored epidermal integrity by inhibiting collagen degradation and DNA damage, while improving skin hydration. In vitro, the administration of GPEVs led to reduced SA-β-gal activity, enhanced cell proliferation, and diminished senescence-associated secretory phenotype (SASP). Mechanistically, GPEVs prevented CTCF-mediated transcriptional activation of aging-related genes via promoting targeted STING degradation. Notably, the therapeutic effects of GPEVs were entirely abolished upon STING agonism, thereby confirming the target specificity. Our study not only establishes GPEVs as a biocompatible nanotherapeutic agent for addressing skin aging but also represents a paradigm-shifting strategy for the utilization of plant-derived extracellular vesicles, bridging critical gaps in current anti-aging dermatology.
