Skin imaging technologies for photoaging / 中华皮肤科杂志

ABSTRACT

Skin 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.
