Skin Didn't Respond to PDT for Back Acne

Question viewed 150 times
I recently underwent PDT with Levulan (60 min) and Blu-U (9 mins) for back acne. Why does my skin not feel burned or appear red?

Need a longer incubation time
I think you need a longer incubation time (ie let the product sit on your back for longer) as well as possibly more time under the blue light.
