Abstract

ABSTRACT The photothermal effect of lasers is minimized and the photoacoustic effect is maximized as the pulse duration is shortened. Therefore, picosecond lasers with a short pulse and high peak power can be used to effectively treat various pigment disorders by reducing tissue damage. The first picosecond lasers were used for tattoo removal; they are also widely used for pigment treatment because of their reduced side effects compared with nanosecond lasers. Recently, picosecond lasers have been shown to be effective in the treatment of various skin conditions such as acne scars and large pores. There are many studies on picosecond lasers; however, there are no studies on a laser with a pulse duration of 300 ps. This report describes the use of a 300 ps Nd:YAG laser for treating pigment disorders and for skin rejuvenation in four Asians, with no side effects. Determining the clinical significance of the 300 ps pulse duration through comparative studies with various picosecond lasers is needed.

脉冲持续时间为300ps的激光在亚洲人皮肤年轻化和治疗色素沉着障碍方面的疗效:一系列四例。

随着脉冲持续时间的缩短，激光的光热效应最小化，光声效应最大化。因此，具有短脉冲和高峰值功率的皮秒激光可以通过减少组织损伤来有效地治疗各种色素紊乱。皮秒激光首次用于去除纹身;与纳秒激光相比，它们的副作用更小，因此也被广泛用于色素治疗。最近，皮秒激光已被证明是有效的治疗各种皮肤状况，如痤疮疤痕和大毛孔。皮秒激光器的研究有很多;然而，目前还没有关于脉冲持续时间为300ps的激光的研究。本报告描述了在四个亚洲人身上使用300ps Nd:YAG激光治疗色素紊乱和皮肤年轻化，没有副作用。需要通过与各种皮秒激光器的比较研究来确定300ps脉冲持续时间的临床意义。
