Abstract: Objective To evaluate the efficacy and safety of AlumaTM functional aspiration controlled electrothermal stimulation （FACES） radiofrequency in the treatment of skin wrinkles and laxity on the face and neck. Methods A total of 30 volunteers with aging skin were recruited in the study. All volunteers were treated with AlumaTM FACES radiofrequency for 6 times at 2-week interval. Photographs were taken for volunteers before every treatment and 1 month after the last treatment. Improvement in lesions was objectively assessed by two double-blinded physicians based on the photographs of volunteers taken before the first, fourth and sixth treatment, and 1 month after the last treatment. Patient satisfaction was measured by questionnaire. Adverse effects were recorded. Results Totally, 24 volunteers completed the treatment. Improvement of lesions was achieved in 66.7% of the volunteers after 3 treatments, 90.5% after 5 treatments, and 94.4% one month after the last treatment. About 50% of the volunteers were satisfied with the effect after 3 treatments, 90.5% after 5 treatments, and 100% one month after the last treatment. Slight purpura was the most common side effect. Conclusion Radiofrequency therapy is effective for skin wrinkles and laxity on the face and neck, without obvious side effect.
