<b>Background:</b> Abnormal scarring and fibrotic skin disorders arise from dysregulated wound healing processes. While Aloe vera is widely recognized for its therapeutic properties, the potential of its extracellular vesicles (Av-EVs) remains underexplored.<b>Objective:</b> This study aimed to isolate and characterize Av-EVs and evaluate their antioxidant, anti-inflammatory, and antifibrotic properties <i>in vitro</i>, focusing on the impact of extraction method and plant maturity.<b>Methods:</b> Av-EVs were isolated from mature and young Aloe vera leaves using manual (NB) or blender-based (B) homogenization. Vesicles were characterized by nanoparticle tracking analysis, transmission electron microscopy, and protein quantification. Antioxidant and cytotoxicity assays (DPPH, alamarBlue) were followed by functional anti-inflammatory and antifibrotic analyses respectively in LPS-stimulated THP-1 macrophages and TGF-β1/Vitamin C-activated human dermal fibroblasts (RT-qPCR, immunofluorescence, proteomics).<b>Results:</b> NB-derived EVs from mature leaves exhibited the most potent activity across all assays, showing superior antioxidant capacity, greater suppression of pro-inflammatory cytokines, enhanced M2 macrophage polarization, and significant downregulation of COL1A1 and α-SMA. In contrast, B-derived and young leaf-derived EVs showed reduced bioactivity, with young EVs failing to inhibit fibrotic markers.<b>Conclusion:</b> Manually extracted Av-EVs from mature leaves demonstrate superior multifunctional bioactivity, highlighting their potential as plant-derived nanotherapeutics for fibrotic scar modulation.
