Conventional vs. daylight methyl aminolevulinate photodynamic therapy for actinic keratosis of the face and scalp: an intra‐patient, prospective, comparison study in Italy

Abstract

MAL DL-PDT showed similar efficacy to c-PDT in the treatment of AK I of the face/scalp but was less effective than c-PDT for AKs II and III. DL-PDT was better tolerated being associated with lower pain and occurrence of fewer adverse events. Clinical response to DL-PDT was significantly moderated by outdoor temperature, increasing at higher temperatures.
