由于点阵激光具有疗效肯定,安全性高和停工期短等优点,已成功用于治疗痤疮瘢痕和光老化等.与传统的剥脱性和非剥脱性激光不同,点阵激光仅作用部分皮肤,保留周围正常皮肤,从而有利于快速愈合和减少停工期.点阵激光通过微治疗孔传递高能量到达真皮层,从而保证疗效,而避免传统剥脱性激光容易出现的风险为持续性色素减退和瘢痕.概述近几年剥脱性和非剥脱性点阵激光在瘢痕、光老化、萎缩纹、色素性疾病、脱发和点阵激光经皮给药等的临床应用、机制和疗效.

Because of definite efficacy,high safety and short downtime,fractional lasers have been successfully used for the treatment of acne scars and photoaging.Unlike traditional ablative and nonablative lasers,fractional lasers only act on some regions of the skin without involvement of surrounding nomal skin,allowing a rapid healing with short downtime.Fractional lasers deliver high energy to the dermis through micropores,which ensures efficacy and avoids common adverse reactions induced by traditional ablative lasers,such as permanent depigmentation and scarring.In this review,the authors summarize clinical application,action mechanism and efficacy of ablative and non-ablative fractional lasers in the treatment of scars,photoaging,striae atrophicae,pigmentary disorders,baldness,as well as in transdermal drug delivery.
