Traditional treatments may pose safety risks and cause side effects. As an emerging research direction, plant-derived exosome-like nanoparticles (PDNPs) show promise in combating aging. Aloe vera, known for its natural active ingredients that benefit the skin, aloe-derived exosome-like nanoparticles (ADNPs) have not yet been studied for their potential in delaying skin aging.Methods: In this study, nanoparticles were isolated from two different sites, aloe vera gel and aloe vera rind (gADNPs and rADNPs), and characterized by TEM, SEM, AFM, NTA and BCA. The effects were evaluated by constructing in vitro and in vivo models and using RT-qPCR, immunofluorescence, and histopathological analysis.Results: The results first revealed the exceptional anti-aging effects of ADNPs. We found that ADNPs promoted the nuclear translocation of Nrf2, alleviated oxidative stress and DNA damage induced by UV exposure, and inhibited the elevation of β-gal and SASP. In vivo, ADNPs reduced MDA and SOD levels in mouse skin tissue and delayed skin photoaging. Moreover, safety assessments confirmed the excellent biocompatibility of ADNPs.Conclusion: ADNPs delay skin photoaging through the Nrf2/ARE pathway, holding potential clinical application value, and may provide new therapeutic strategies for future medical cosmetology and skin disease prevention.
