The study analyzed dermoscopic images before and after laser treatment of vasodilatory dermatosis in 18 patients with a total of 37 lesions. The vascular characteristics of the lesions were recorded and the status of their disappearance was evaluated after one month. Total vascular function scores were significantly different from individual vascular scores before and after treatment. The clearance rate after one session was 75.7% (28 of 37 lesions). There were significant differences in scores between cleared and untreated lesions. Vascular color was identified as an independent factor influencing lesion clearance. Lesions with scores below 9.5 are more likely to be removed in a single session. Before treatment, the dermatoscope objectively assesses the vascular structures and makes it possible to predict the success of therapy for personalized plans.
