Objective: To investigate the effectiveness and safety of 4 MHz monopolar radiofrequency in enhancing facial wrinkles. Methods: A prospective experimental study was conducted involving 62 facial skin aging patients treated at the Medical Cosmetic Dermatology Department of Shangqiu First People’s Hospital between June 2022 and December 2022. These patients received treatment using a 4 MHz monopolar radiofrequency device. Patients with facial skin aging underwent Fitzpatrick facial wrinkle grading and VISIA image acquisition at baseline, immediately after treatment, and 30‐ and 90‐days post‐treatment; adverse events were also recorded. Results: After administering noninvasive radiofrequency treatment to 62 patients with facial skin aging, 41 demonstrated significant improvement 90 days post‐treatment, with 17 classified as effective and 4 as ineffective. The overall clinical effectiveness rate was 93.55%. Ninety days following radiofrequency therapy, Fitzpatrick facial wrinkle grading was repeated for the patients with facial skin aging. Fifteen patients were classified as Grade I, 28 as Grade II, and 19 as Grade III, revealing significant differences before and after treatment ( χ 2 = 16.1, p = 0.013). Adverse reactions were limited to mild erythema and edema, and no complications such as postinflammatory hyperpigmentation, epidermal burns, fat atrophy, or scarring, were observed in any patients. Conclusion: The application of monopolar radiofrequency for facial rejuvenation is safe, effective, and associated with minimal adverse reactions.
