1. We will lead you to our procedure room and informed consent will be obtained.
2. We will cleanse your face with alcohol/acetone
3. Levulan (a photosensitizing chemical) will be applied to the treatment area.
4. The Levulan will need to incubate for one to two hours prior to illumination with light. You are permitted to leave the office during the incubation, but you are not permitted to wash your face during this time.
In general, lesions on the face need to incubate for 60 minutes, whereas lesions on the scalp need to incubate for 60 to 120 minutes depending on the thickness of the lesions. In addition, the scalp will be occluded with Saran wrap after application of Levulan to enhance penetration.
On occasion, loose scale or crust will be gently removed from the skin surface.
5. Once incubation is complete, you will be positioned underneath the U blue light (for 17 minutes) at which time the photodynamic reaction occurs.
6. It is normal to experience a burning sensation while you are exposed to the light. We will hand you a fan to help cool the area during the treatment. But if the reaction is too intense, we can temporarily pause the treatment. Less than 3% of people discontinue treatment due to severe burning and stinging.
