Chronic diabetic foot ulcers (CDFUs) are complex pathological processes involving persistent inflammation, significantly impacting a patient's quality of life. Resveratrol (RES), recognized for its potent antioxidant and anti-inflammatory properties, faces challenges regarding its permeability. This study aimed to develop Resveratrol glycerosomal nanovesicles (RES-GLY-NVs) for topical application to enhance skin permeation. The optimized formulation was integrated into a 2 % HPMC gel and subjected to comprehensive physicochemical characterization, skin deposition, in vitro release, microbiological, antioxidant, and in vivo assessments. Results revealed RES-GLY-NVs with particle size ranging from 82.19 ± 6.51 nm to 145.70 ± 1.39 nm with PDI less than 0.5, encapsulation efficacy ranging from 89.14 ± 1.39 % to 96.09 ± 2.13 % and a zeta potential ranging from −27.93 ± 6.47 mV to −49.33 ± 1.89 mV. The release profile of RES was obviously ranging from % 54.40 ± 1.71 to 77.47 ± 0.54 % after 8 h. In vitro cell assessment revealed that RES-GLY-NVs have no cytotoxicity on normal cells. The optimized RES-GLY-NVs-HPMC gel displayed pseudoplastic rheological behavior and significantly enhanced RES flux and permeability through excised rat skin compared to plain gel. The In vivo study and histological evaluation of diabetic rats ensured that RES-GLY-NVs-HPMC gel acts as a more effective healing adjunct compared to free RES and conventional therapy. These findings encourage the utilization of RES-GLY-NVs-HPMC gel as a wound-healing drug delivery system in chronic diabetes-related wounds and ulcers.
