GinExtraMed: Focus on Rosa canina L. Extract Encapsulated into Glycethosomes and Allanthosomes for Accelerating Skin Wound Healing

Background/Objectives: Over the last decade, the development of innovative wound products has continued to be a focus of intense research to meet the huge demand of patients. The aim of this work was to develop novel medicated Spanish broom wound dressings capable of releasing Rosa canina extract, recognized for its high antioxidant activity. Methods: Rosa canina extract was encapsulated in two different nanocarriers, namely glycethosomes and allanthosomes. The physico-chemical and functional characteristics of the obtained vesicles were described, including their size, particle size distribution, zeta potential, and encapsulation efficiency (EE). In addition, vesicles cytotoxicity and cell proliferation were evaluated on human fibroblasts. Furthermore, loaded vesicles were sunk into Spanish broom dressings, analyzed by confocal microscopy, and, finally, evaluated for their wound healing ability by scratch test. Results: Both carriers are nanometric in size, with a good EE (>70%), and a negative zeta potential. Additionally, vesicles are biosafe, non-cytotoxic, and lead to complete closure of the scratch in about 30 h. Conclusions: The findings showed that the developed Spanish broom dressings have the potential to be an efficient and innovative wound care product for accelerating skin wounds.
