Fractional laser in the treatment of melasma

点阵激光是皮肤激光美容领域的一种新技术,近年来在黄褐斑的治疗中显示出良好的前景.点阵激光的作用原理是局灶性光热作用,是选择性光热作用的一个重要拓展和延伸.点阵激光可分为非剥脱性点阵激光和剥脱性点阵激光,对黄褐斑有一定的疗效,改善程度不一,有的甚至加重,其疗效与治疗参数的选择、皮肤类型、术后护理、黄褐斑类型等有关.不良反应主要为短暂性红斑、水肿、灼热和疼痛感等,患者可耐受,但炎症后色素沉着发生率相对较高.Fractional laser,a new design for cosmetology,has shown a promising prospect in the treatment of melasma. It acts mainly through local photothermolysis, a new concept of selective photothermolysis.There are two kinds of fractional laser,nonablative and ablative,both of which are somewhat effective in the treatment of melasma.The efficacy of fractional laser is associated with therapeutic parameters,Fitzpatrick skin types,post-therapeutic management,types of melasma,and so on.The side effects of fractional laser mainly include temporary erythema,edema,burning and pain,which are often tolerable.Postinflammatory hyperpigmentation appears to be the most common adverse reaction.中国科技核心期刊(ISTIC)0281-833
