How many phototherapy sessions will I need?

Phototherapy normally involves several treatment sessions per week, and how many you need depends on the type of phototherapy you are having. Your dermatologist will tell you how many treatment sessions you can expect to need before you start your treatment. Treatments will continue until your skin is clear. You may also need occasional maintenance sessions in the future.
