Summary
Photodynamic therapy (PDT) is a treatment option for acne patients who fail to respond to conventional therapy. Although potent, we experience side effects such as erythema, exfoliation and dyspigmentation. In attempt to specify treatment and shorten the incubation time, we injected 5-aminolevulinic acid (ALA) to the individual lesion. The results of intralesional injection ILI-PDT and conventional PDT are compared in this study.
