Light therapy, also known to many as phototherapy, is another treatment that can be used to help alleviate some of the varied symptoms of psoriasis. During the process, a medical professional shines ultraviolet light on the skin, and these treatments must be scheduled on a regular basis. Keep in mind that overexposure to sunlight or UV rays can often make psoriasis worse, so don’t try to compensate with using a tanning bed if you can’t get into the doctor’s office for the treatment. Light therapy is completely different, and must be administered in a doctor’s office.
