Safety and Efficacy Evaluation of the Monopolar Radiofrequency Device for the Improvement of Facial Wrinkles

The goal of this clinical trial is to evaluate the safety and efficacy of the monopolar radiofrequency therapy device developed by CLASSYS Inc. for improving facial and periorbital wrinkles. This is a prospective, multicenter, evaluator-blinded, randomized, parallel-controlled, non-inferiority clinical trial. The main questions the study aims to answer are: Does the monopolar radiofrequency device improve the appearance of facial and periorbital wrinkles? Is the safety profile of the monopolar radiofrequency device acceptable? Researchers will compare the investigational device to the Thermage CPT System (Solta Medical Co., Ltd.) to see if the monopolar radiofrequency device is non-inferior in terms of wrinkle improvement. Participants will: Undergo a single treatment session with either the investigational device or the control device. Be followed up for a period of 3 months to assess wrinkle improvement and safety outcomes. The primary outcome will be the improvement in facial and periorbital wrinkles, measured by the Facial Wrinkle and Elasticity Scale (FWES), 3 months post-treatment. Secondary outcomes include the Global Aesthetic Improvement Scale (GAIS) and a Visual Analog Scale (VAS) for pain. Safety evaluations will include adverse event (AE) and serious adverse event (SAE) monitoring.
