Phototherapy might sound complicated, but it's really quite simple. It involves exposing your skin to ultraviolet (UV) light. It's a treatment you can do on your own or have a medical professional perform.
Do-it-yourself phototherapy is as simple as exposing your skin to natural sunlight. However, for the best way to do so without also putting yourself at greater risk for sun damage or skin cancer, you should ask your doctor for guidelines.
