Mechanism of Action
These nano-sized exosomes function as highly efficient delivery vehicles, facilitating the penetration of bioactive compounds into skin cells through specific endocytic pathways like clathrin- and caveolae-mediated endocytosis, alongside membrane fusion. Once absorbed, they act as humectants, attracting and retaining moisture, while also conditioning and protecting the skin. Their core mechanism involves reducing pro-inflammatory cytokines such as TNF-α and IL-1β, simultaneously amplifying the skin's natural antioxidant defenses via the Nrf2/HO-1 pathway. This collective action supports wound healing, diminishes inflammation and redness, enhances skin hydration, and fortifies the skin barrier.

Key findings
- 01 Cellular studies demonstrate that Aloe-derived extracellular vesicles (EV_Aloe) exhibit minimal toxicity to macrophages at concentrations up to 200 µg/mL, effectively modulating macrophage polarization.
- 02 Aloe vera peel-derived extracellular vesicles (A-EVs) show dose-dependent antioxidant activity against oxidative stress in H2O2-treated HaCaT cells through Nrf2 activation, with SOD activity increasing by over 40% at higher doses.
- 03 Aloe saponaria-derived extracellular vesicles (AS-EVs) significantly reduce pro-inflammatory gene expression (IL-6, IL-1β) in LPS-stimulated macrophages, promote the proliferation and migration of human dermal fibroblasts, and enhance angiogenesis by improving tube formation in human umbilical vein endothelial cells.

Stability
Aloe vera-derived nanovesicles exhibit excellent intrinsic stability, showing superior resilience compared to traditional liposomes, even in harsh oxidative conditions. They remain stable for extended periods when stored at -80 °C, though the viscosity of the initial aloe juice can influence isolation efficiency and yield.
Safety
Safety Profile
While the CIR Expert Panel concluded that general Aloe Barbadensis Leaf ingredients are safe if anthraquinone levels do not exceed 50 ppm, and there are specific FDA and IARC classifications for whole leaf extract (not isolated vesicles), specific safety evaluations for Aloe-derived vesicles indicate low cytotoxicity, high biocompatibility, and no significant hemolysis or immune stimulation.
