The field of nonsurgical laser resurfacing for aesthetic enhancement continues to improve with new research and technological advances. Since its beginnings in the 1980s, the laser-resurfacing industry has produced a multitude of devices employing ablative, nonablative, and fractional ablative technologies. The three approaches largely differ in their method of thermal damage, weighing degrees of efficacy, downtime, and side effect profiles against each other. Nonablative technologies generate some interest, although only for those patient populations seeking mild improvements. Fractional technologies, however, have gained dramatic ground on fully ablative resurfacing. Fractional laser resurfacing, while exhibiting results that fall just short of the ideal outcomes of fully ablative treatments, is an increasingly attractive alternative because of its far more favorable side effect profile, reduced recovery time, and significant clinical outcome.
非手术激光美容领域随着新的研究和技术进步不断发展。自 20 世纪 80 年代以来，激光美容行业已经生产出了多种采用磨蚀性、非磨蚀性和分数磨蚀性技术的设备。这三种方法在热损伤方式、疗效、停机时间和副作用方面存在很大差异。虽然非磨蚀性技术只对那些寻求轻度改善的患者群体有一定的吸引力，但它们还是引起了人们的兴趣。然而，分数性技术在完全磨蚀性换肤方面取得了显著进展。尽管分数性激光换肤的效果仅略低于完全磨蚀性治疗的理想效果，但由于其副作用谱更有利、恢复时间更短以及显著的临床效果，它已成为一种越来越有吸引力的替代方法。
