Purpose: extract (GLE) can enhance mitochondrial function to promote wound healing in aging skin. Methods: Natural senescent human foreskin fibroblasts (BJ) were treated with varying concentrations of GLE, and safe concentrations were determined using the cell counting kit-8 (CCK-8) assay. The levels of mitochondrial reactive oxygen species (ROS) and mitochondrial membrane potential (MMP) were measured. Animal experiments were conducted to validate GLE's effects on wound healing by assessing adenosine triphosphate (ATP) and ROS levels in skin tissues. Results: GLE exhibited no cytotoxicity within a concentration range of 0-100 µg/mL. Simultaneously treating senescent BJ cells with 50 µg/mL or 100 µg/mL of GLE can significantly enhance cell viability. Treatment with 100 µg/mL GLE significantly increased MMP levels while reducing mitochondrial ROS levels. Hydrogel containing 2% GLE applied to injured skin promoted wound healing, increased the ATP level of the wound tissue, and decreased ROS levels in skin tissues. Conclusion: These findings suggest that GLE can improve mitochondrial function in aging skin and promote wound healing.
