Background/purposeA relatively long incubation time is needed for photosensitizer absorption in conventional photodynamic therapy (PDT) for actinic keratosis (AK). The use of ablative CO2 fractional lasers (AFXLs) to increase drug delivery could shorten the incubation time. Here, we aimed to compare the efficacy between AFXL‐assisted PDT with a short incubation time and conventional PDT for AK.
