<scp>UniPolar</scp> Radiofrequency for Treatment of Facial Aging Signs and Skin Laxity

ABSTRACT Background Radiofrequency (RF) technologies are widely used for noninvasive skin rejuvenation. Unlike other RF technologies, unipolar RF emits an electromagnetic field that produces controlled heat within the adjacent area, promoting collagen remodeling and improving the visible signs of skin aging. Objective This study evaluated the safety and efficacy of unipolar RF in improving facial skin laxity and wrinkles. Methods A retrospective analysis was conducted on n = 93 patients treated with a unipolar RF applicator. Clinical outcomes were assessed using the Global Aesthetic Improvement Scale (GAIS) and Modified Fitzpatrick Wrinkle and Elastosis Scale (MFWS). Blinded evaluators compared pre‐ and posttreatment photographs, and patient‐reported outcomes, treatment‐associated pain, and overall satisfaction were also analyzed. Results GAIS showed overall improvement (mean score 1.9 ± 0.5) and MFWS values decreased following treatments (mean change −0.3 ± 0.3; p &lt; 0.001). A significant negative correlation between GAIS and MFWS reduction ( p &lt; 0.001) as well as a positive correlation for higher treatment numbers and GAIS outcome were found. Patients rated their satisfaction as “satisfied” to “much satisfied.” No serious adverse events were reported. Conclusion Unipolar radiofrequency demonstrated significant improvements in facial skin laxity and wrinkles with minimal discomfort and a high safety profile.
