摘要皮肤光老化影响美观且与皮肤肿瘤相关，对光老化进行客观有效的评估非常重要。组织病理是光老化诊断的金标准，但因有创，不宜重复使用，不利于光老化的动态监测和评估。皮肤影像技术可在体、实时、无创地实现二维或三维图像分析，能够补充皮肤光老化的视觉评估。本文综述皮肤镜、反射共聚焦显微镜、皮肤高频超声和光学相干断层扫描在评估光老化方面的研究进展。

abstractsSkin photoaging not only affects the appearance, but also is associated with skin tumors. It is very important to objectively and effectively evaluate photoaging. Histopathological examination is the gold standard for the diagnosis of photoaging, but it can not be used repeatedly because of its invasiveness, and is not suitable for dynamic monitoring and evaluation of photoaging. Skin imaging technologies can realize in vivo, real-time and non-invasive two- or three-dimensional image analysis, which facilitate the visual assessment of skin photoaging. This review summarizes research progress in dermoscopy, reflectance confocal microscopy, high-frequency ultrasound and optical coherence tomography in evaluation of photoaging.
