Objectives: Skin laxity due to aging is a disease directly related to the patient's psychological problems and the quality of life that interferes with daily life. Therefore, prevention and timely treatment are needed. Radiofrequency has emerged as a leading technology for preserving facial elasticity, attributed to its enduring effects and significant improvement outcomes. Radiofrequency therapy is based on the principle of using high-frequency electrical energy to transfer heat energy to body tissues. Introduction: We developed a Monopolar Radiofrequency device to improve patient comfort during the procedure and achieve treatment effectiveness in a single session through enhanced energy delivery. This study presents the outcomes of applying innovative technology while developing a monopolar radiofrequency device. Materials / method: The developed device measures impedance in real-time and provides feedback regardless of skin type. Patients find enhanced energy delivery favorable because it improves their pain during the procedure and achieves treatment effectiveness with only one session. This enables customized treatments tailored to individual skin conditions, leading to more effective outcomes. Achieving uniformity in the heating pattern has minimized uneven areas on the skin surface, enhancing safety and efficacy. Results: The treatment mechanism combines cooling and heating to deliver uniform energy to subcutaneous tissue while cooling the epidermis. We observed temperature changes in tissue depth depending on the irradiation method, confirming the efficacy of various cooling combinations and the impact of cooling time on temperature changes. Regardless of the irradiation method, cooling was consistently applied to the skin surface while heat was generated in deep tissues. Conclusion: Developing a monopolar radiofrequency treatment device represents a novel approach to facial rejuvenation. Incorporating technical features such as heat transfer methods, skin surface cooling, pain reduction with vibration, and real-time impedance matching enhances treatment effectiveness and patient satisfaction. These technical advancements provide a new perspective on facial rejuvenation, offering a promising solution for addressing aging-related concerns with improved efficacy and comfort.
