与使用高频超声皮肤成像的微聚焦超声相比，红外技术对面部皮肤厚度的影响：一项随机临床试验

摘要(中文译文)

基于能量的设备在面部皮肤老化的美容医学治疗中发挥着关键作用。非剥脱性热提拉可改善皮肤紧致度和弹性。本随机试验评估Zaffiro®红外技术与微聚焦超声（MFU）对真皮厚度及面部皮肤年轻化的影响。三十名健康女性按1：1随机分为两组：Zaffiro®组（n=15）和MFU组（n=15）。每组接受单次治疗，并于30、60和90天时进行评估。采用高频超声成像评估真皮厚度。记录皱纹严重程度（Fitzpatrick皱纹量表）、受试者整体美学改善量表（SGAIS）、患者满意度及治疗耐受性。两组真皮厚度均增加约40%。皱纹减少幅度在Zaffiro组达52.8%，MFU组为40.5%。30天时，62%的Zaffiro组患者报告显著改善，MFU组为15%。30天时满意度分别为85%（Zaffiro）和61%（MFU）；90天时两组均为92.5%。两种技术均改善了真皮厚度和皱纹严重程度。Zaffiro在美学效果和舒适度方面表现出更早且更大的改善，使其成为一种有利的无创治疗方法。

Abstract

Energy-based devices play a crucial role in aesthetic medicine for treating facial skin aging. Non-ablative thermolifting improves skin firmness and elasticity. This randomized trial evaluates Zaffiro® infrared technology and microfocused ultrasound (MFU) on dermal thickness and facial skin rejuvenation. Thirty healthy women were randomized (1:1) into two groups: Zaffiro® ( = 15) and MFU ( = 15). Each received a single treatment session and was evaluated at 30, 60, and 90 days. High-frequency ultrasound imaging assessed dermal thickness. Wrinkle severity (Fitzpatrick Wrinkle Scale), Subject Global Aesthetic Improvement Scale (SGAIS), patient satisfaction, and treatment tolerance were recorded. Both groups showed a ~ 40% increase in dermal thickness. Wrinkle reduction reached 52.8% in Zaffiro vs 40.5% in MFU. At 30 days, 62% of Zaffiro patients reported significant improvement vs 15% in MFU. Satisfaction was 85% (Zaffiro) and 61% (MFU) at 30 days; 92.5% in both groups at 90 days. Both technologies improved dermal thickness and wrinkle severity. Zaffiro demonstrated earlier and greater improvements in aesthetics and comfort, making it a favorable noninvasive treatment.
