Photodynamic therapy for precancerous lesions

I am 48 and my doctor saw a legion on my nose she did not like . I met with two dermatologists and both recommended the levulan photodynamic therapy. The actual process was easy and not as painful as others described. I waited two hours in the office with the stuff on my face. I watched Netflix’s. The light was then put on for twenty minutes , not a big deal.
I looked like I had a bad sunburn. I drove home with my face covered and spent the next three days in my house in the dark. I was taking no chances.
I am not on day 4 and the blisters are looking better , but there is a lot of peeling .
