A faster healing process was observed in superficial skin wounds after irradiation with the EMOLED photocoagulator. The instrument consists of a compact handheld photocoagulation device, useful for inducing coagulation in superficial abrasions. In this work we present the results of an in vivo study, in a murine model. Two superficial wounds were produced on the back of 12 mice: one area was left untreated, the other one was treated with EMOLED. Healthy skin was used as a control. The animals were sacrificed 3 hours, 12 hours, 1 day, 6 day after treatment. The treatment effects on back skin was monitored by visual observations, histopathological analysis, immuno-histochemical analysis, and nonlinear microscopic imaging performed at each follow up time, finding no adverse reactions and no thermal damage in both treated areas and surrounding tissues. In addition, a faster healing process, a reduced inflammatory response, a higher collagen content, and a better-recovered skin morphology was evidenced in the treated tissue with respect to the untreated tissue. These morphological features were characterized by means of immuno-histochemical analysis, aimed at imaging fibroblasts and myofibroblasts, and by SHG microscopy, aimed at characterizing collagen organization, demonstrating a fully recovered aspect of dermis as well as a faster neocollagenesis in the treated regions. This study demonstrates that the selective photothermal effect we used for inducing immediate coagulation in superficial wounds is associated to a minimal inflammatory response, which provides reduced recovery times and improved healing process.
