Evaluation of skin barrier function based on skin dermoscopic features in patients with rosacea

[...]we analyzed dermoscopic images as a skin barrier function evaluation method and compared the results with those of the GPSkin Barrier, establishing the feasibility of dermoscopy as a skin barrier function evaluation method. The study protocol was approved by the Institutional Review Board of the First Affiliated Hospital of Nanjing Medical University (No. 2020-SRFA-082). [...]specific dermoscopic features could be used as indicators of skin barrier function in patients with rosacea, suggesting that these skin barrier function changes may be “visualized.”
