Faster recovery and fewer scars are ideal wound healing. We have demonstrated that the cannabinoid receptor 2 (CB 2 ) agonist Gp1a is beneficial to skin wound healing, which inhibits inflammation and fibrogenesis while promoting re-epithelialization. However, the systemic administration is imprecise and overqualified for a local skin wound. Herein, we prepared Gp1a-gel using triglycerol monostearate (Tm) hydrogel and detected whether the Gp1a-gel worked effectively on mouse skin excision wounds. The results showed that Gp1a-gel might sustainably increase the CB 2 for at least 8 days. It decreased inflammation and fibrogenesis while promoting wound enclosure and re-epithelialization. These results suggested Gp1a-gel may utilize as a potential formulation strategy to treat the skin wound.
