I saw your post from 2024 and want to share something that may be useful. Regarding us of PDT and the pain that it produces I am a frequent patient of PDT and in past two years have tried a “pain free” approach that was researched at the Cleveland Clinic and was discussed in dermatology journals including the National Library of Medicine, about 4 or 5 years ago. This alternative approach has the chemical solution applied to the skin and then followed immediately by 30 minutes under the light. No incubation period like before. The pain during the 30 minutes is very slight, by comparison to traditional regimen. And the pain level day 1 to 3 after is far less in my experience. I have had this approach 3 times versus a dozen or more under the conventional method over the past ten years.
The redness and crusting that I have afterward seems to be much less. Overall healing time is about the same.
I used to dread the PDT appointment and now it is no big deal! Per the research done the effectiveness of the process on treating the skin is equal . My dermatologist was aware of this option agreed to trying it after a i brought up the Cleveland Clinic article.
Obviously check with your doctor and refer them to the Cleveland Clinic information on file at their Department of Dermatology.
