Modern aspects of photodynamic therapy of actinic keratoses

open access: yesBiomedical Photonics, 2019
Currently, photodynamic therapy (PDT) remains the most effective treatment for actinic keratosis (AK). With the increase in the incidence of AK, mainly due to the popularization of recreation in countries with increased insolation, there is an increasing
