Abstract:
Objective:To observe the efficacy and safety of micro-focusing ultrasound (MFU) combined with dye pulsed light (DPL) in the treatment of facial skin aging.Methods:A retrospective study was conducted in 133 patients treated for facial skin aging at Zhiyan Medical Beauty Clinic, the Fifth Affiliated Hospital of Guangzhou Medical University, and Sun Yat-sen Memorial Hospital of Sun Yat-sen University from May to September 2023. There were 46 males and 87 females, aged 24-45 (34.5±3.7) years. Patients were divided into two groups based on the treatment they received: combined treatment group: 55 cases, treated with MFU combined with DPL; control group: 77 cases, treated with MFU only. After the completion of treatment in all patients, three clinical physicians evaluated the pre-treatment and immediate post-treatment photos for efficacy, including improvement, deterioration, and ineffectiveness. The pain degree scores and skin reaction scores were compared between the two groups. The occurrence of adverse reactions was recorded.Results:After treatment, the improvement rate of all patients was 100 % (133/133). The pain score of the combined treatment group was 0.10 (0.05, 0.20) points, and that of the control group was 0.75 (0.60, 0.90) points. The difference was statistically significant between the two groups ( Z=-6.66, P<0.001). The skin reaction score of the combined treatment group was 0.40 (0.20, 0.60) points, and that of the control group was 1.20 (0.90, 1.50) points. The difference was statistically significant between the two groups ( Z=-5.18, P<0.001). There were no treatment site wounds and other serious adverse reactions during the treatment of all patients. Conclusion:MFU combined with DPL is effective in the treatment of facial skin aging without serious adverse reactions.
