To date, there is no treatment with an adequate benefit-risk balance. Photodynamic therapy is proposed as one of the most effective therapeutic tools.

The objective of this review is to analyze the most recent evidence on the therapeutic performance of photodynamic therapy in the management of actinic keratosis. A literature search was conducted in the PubMed, Scopus, and MEDLINE databases. Based on the most recent randomized controlled trial comparing the use of dynamic phototherapy combined with aminolevulinic acid without incubation versus incubation for one hour, it was found that the intervention group had a higher percentage of lesion resolution compared to the control grou...
