Is phototherapy a common treatment for pityriasis rosea?

Phototherapy can take the form of exposing the skin to sunlight or to an ultraviolet B light. Either one can help alleviate the symptoms of pityriasis rosea. It reduces itching and heals the rash faster. The ultraviolet B light (or UVB) exposure is done at the doctor's office. If you would like to try natural sunlight, you should consult your doctor first. Both types of phototherapy may cause the spots of the rash to darken and remain visible after the rash is gone.
