Acne scarring is a common sequela of acne vulgaris, which seriously affects facial esthetics. The treatment options for acne scars vary depending on the development stage, color, type, and location of scarring. The objective and precise assessment of acne scars is a prerequisite for treatment, and it is also an important means of monitoring the treatment effect. The traditional methods to evaluate the types and severity grade of acne scars are primarily based on subjective assessment by physicians, which lacks objectivity and accuracy. Novel noninvasive skin imaging techniques, such as skin surface imaging analysis systems, dermoscopy, reflectance confocal microscopy (RCM), high-frequency ultrasound (HFUS), optical coherence tomography (OCT), and multiphoton tomography (MPT), provide new tools for the rapid and objective assessment of acne scars. This article reviews the progress of skin imaging techniques in the diagnosis, classification, and efficacy evaluation of acne scars.
痤疮瘢痕是寻常型痤疮的常见后遗症，严重影响面部美观。痤疮瘢痕的治疗选择取决于瘢痕的发展阶段、颜色、类型和位置。痤疮瘢痕的客观、准确评估是治疗的前提，也是监测治疗效果的重要手段。传统的评估痤疮瘢痕类型和严重程度的方法主要基于医生的主观评估，缺乏客观性和准确性。新型无创皮肤成像技术，如皮肤表面成像分析系统、共聚焦皮肤显微镜、反射共聚焦显微镜、高频超声、光学相干断层扫描和多光子断层扫描，为痤疮瘢痕的快速客观评估提供了新工具。本文综述了皮肤成像技术在痤疮瘢痕诊断、分类和疗效评估中的研究进展。
