Overview
The purpose of the study is to test a new video device for actinic keratoses. The device takes images of your skin lesions during the treatment, to learn whether this device can predict how well the treatment is working.
Description
This intervention is designed to help establish what the optimal conditions are for treating actinic keratoses with photodynamic therapy (PDT). The primary outcome of this study is to determine whether the rate of singlet oxygen (sO2) production and/or the initial intralesional photosensitize (PpIX) levels, can predict the clinical responsiveness of AK lesions to PDT. Participants will receive standard red light PDT treatment, except that lesions will be carefully counted beforehand. During the window of red light illumination, photos and a video of one area of skin will be taken to allow us to monitor the progress of the treatment. Any remaining lesions will be counted upon follow-up.
