Facial skin resurfacing is now possible using short-pulse, high-energy carbon dioxide (CO2) lasers. The laser utilized in this particular paper is the Ultra-pulse CO2 laser. The Ultra-pulse laser represents the first CO2 laser able to vaporize tissue in a single pulse with the use of a large spot size. This laser utilizes the principles of selective photothermolysis. The high-power pulses are completed in less than the thermal relaxation time of skin, estimated to be less than 1 millisecond. This translates into rapid vaporization of tissue with little heat conduction to surrounding tissues. It also should allow a reproducibility of results between practitioners with set parameters not possible with previous CO2 lasers. Clinically, this laser is useful for the removal of skin lesions, and the resurfacing of areas of sun damage, wrinkles and scars. The immediate haemostasis and excellent visibility allows for precise vaporization of abnormal tissue. Rapid and pain-free wound healing is usual. The complication rate would appear to compare very favourably with dermabrasion and chemical peeling techniques.
现在使用短脉冲、高能量二氧化碳（CO2）激光可以进行面部皮肤磨削。本文中使用的激光是超脉冲CO2激光。超脉冲激光是第一种能够通过使用大光斑尺寸在单个脉冲中汽化组织的CO2激光。这种激光利用了选择性光热解原理。高功率脉冲在皮肤的热弛豫时间（估计小于1毫秒）内完成。这意味着组织迅速汽化，很少有热量传导到周围组织。这也应该允许在设定参数下，不同从业者之间的结果具有可重复性，而这是以前的CO2激光所无法实现的。临床上，这种激光可用于去除皮肤病变，以及对受阳光损伤、皱纹和疤痕区域进行皮肤磨削。即时止血和极佳的视野使得能够精确汽化异常组织。通常伤口愈合迅速且无痛。与磨皮术和化学剥脱技术相比，其并发症发生率似乎非常有利。
