Monopolar radiofrequency for dermal temperature regulation and remodeling: A porcine model study

Abstract

BackgroundNoninvasive monopolar radiofrequency (NMRF) is widely used for dermal and subdermal volumetric heating, yet detailed research on its effects on dermal temperature is scarce.AimsThis study evaluates the impact of NMRF on dermal temperature and its potential for dermal remodeling using a porcine model.MethodsNoninvasive monopolar radiofrequency was applied to porcine skin with temperature monitoring via optic fiber technology and forward‐looking infrared thermal imaging. Safety was evaluated using nitro blue tetrazolium chloride assessments, and effectiveness was determined through histological examinations before and after treatment.ResultsNoninvasive monopolar radiofrequency treatment in a porcine model achieved effective dermal remodeling with no thermal damage, recording peak temperatures of 50°C, 60°C, and 70°C. Histological analysis showed increased collagen density, indicating successful tissue remodeling.ConclusionNoninvasive monopolar radiofrequency is effective in delivering controlled dermal heating and enhancing collagen synthesis, promoting safe and efficient skin tightening and dermal remodeling in a porcine model. It presents a viable option for skin rejuvenation therapies.
