Abstract:
Background:This study focuses on the development of a hydrogel wound patch incorporating natural extracts, designed to function as a sun patch. By maintaining a moist environment and delivering bioactive compounds, the patch promotes wound healing while also providing cooling and ultraviolet (UV) protection. This dual-purpose approach enhances skin recovery and shields damaged areas from external stressors. The study aims to optimize the formulation and evaluate its efficacy for both therapeutic and cosmetic applications.
Methods:Hydrogel solutions prepared using acrylamide, glycerol, and carboxymethyl cellulose were enriched with extracts from Saururus chinensis, Styrax japonicus, and Centella asiatica. The enriched solutions were processed into patches and tested for their adhesion, cooling effects, and UV protective abilities. Additionally, the wound healing efficacy was evaluated in a mouse model.
Results:The hydrogel patches demonstrated comparable adhesion properties, effective skin cooling, and high UV protection rates similar to those of commercially available products. In the mouse model, the patches significantly improved wound closure and tissue regeneration in the experimental group as compared to the control group.
Conclusion:The study confirms that hydrogel sun patches enriched with natural extracts have the ability to effectively promote wound healing and offer substantial UV protection and cooling benefits, demonstrating their potential medical and cosmetic applications.
