Fractional laser resurfacing has become an important technique in the management of a number of skin conditions, such as photoaging and scars. A variety of laser wavelengths and delivery systems have been introduced to improve immediate and long-term therapeutic results. The simultaneous emission of CO(2) laser and radiofrequency waves combines epidermal coagulation for a resurfacing effect and dermal denaturization for deeper remodelling. The authors present this new machine together with a preclinical histological study and pilot study on 15 patients suffering from acne scars.
分次激光换肤已成为治疗多种皮肤疾病（如光老化和疤痕）的一项重要技术。人们已引入多种激光波长和传输系统，以改善即时和长期治疗效果。二氧化碳激光和射频波的同时发射，结合了用于换肤效果的表皮凝固和用于更深层重塑的真皮变性。作者介绍了这种新机器，并展示了一项针对15名痤疮疤痕患者的临床前组织学研究和初步研究。
