Science
Mechanism of Action
GEVs operate through multifaceted cellular pathways to enhance skin health. They exert anti-senescence and anti-pigmentation effects by precisely downregulating specific molecules associated with skin aging and melanogenesis in both dermal fibroblasts and melanocytes exposed to UV radiation. These vesicles promote skin regeneration by stimulating cell migration and activating the TGF-β/SMAD signaling pathway, which upregulates essential collagen synthesis genes. GEVs effectively penetrate skin cells, increasing the synthesis of crucial structural proteins such as collagen, elastin, and fibronectin, and stimulating keratinocyte proliferation via the AKT/mTOR pathway. Furthermore, they provide protection against UV irradiation and oxidative stress by suppressing activator protein-1 (AP-1) signaling and mitigating the generation of reactive oxygen species (ROS). Their anti-inflammatory action involves reducing the expression of inflammatory proteins like COX-2 and IL-6, and modulating key signaling pathways by inhibiting H2O2-induced ERK and JNK phosphorylation while suppressing MEK1/2.

The Formula
Formulation
Stability
As nano-sized lipid bilayer structures, the stability of Panax Ginseng Adventitious Root Extracellular Vesicles relies critically on maintaining membrane integrity. Formulations should be carefully monitored through physicochemical checks (pH, osmolality, viscosity/rheology) both before and after vesicle incorporation to ensure vehicle compatibility. Conditions that could compromise membrane integrity or promote aggregation should be avoided. A skin-compatible pH range of approximately 4.5–6.5 is generally recommended for topical formulations containing plant-derived extracellular vesicles, though isolation protocols have utilized a pH of 7.4.
Safety
Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has deemed Panax spp. root-derived ingredients generally safe under current practices of use and concentration. It is important to note that this assessment pertains to ginseng root ingredients broadly and not specifically to the extracellular vesicles. However, in vitro studies have demonstrated high cell viability (>80%) at elevated concentrations of ginseng root-derived extracellular vesicles, indicating a low cytotoxicity profile.
