Abstract: 【Abstract】 Actinic keratosis (AK) is a kind of precancerous skin lesions related to long-term light exposure, and photodynamic therapy is one of its main treatment methods. Compared with conventional photodynamic therapy (C-PDT), daylight photodynamic therapy (DL-PDT) with daylight as a light source has advantages of more convenient operation, less pain and higher patient acceptability, but it is liable to be affected by weather and other factors. DL-PDT is suitable for the treatment of grade Ⅰ or Ⅱ AK on the head and face, and its efficacy may be affected by pretreatment, photosensitizers, irradiation dose, etc. This review mainly elaborates the advantages of DL-PDT and introduces its operation methods to help clinicians choose the best treatment protocol for AK.
