Light therapy is a method used for the treatment of skin
diseases such as psoriasis and atopic dermatitis, psychiatric disorders, and
more comprehensively, anticancer therapy using the components of sunlight.
Among these, light therapy for skin diseases has a very long history. From around
2000 BC, ancient Egypt and India have been treating skin diseases by applying
plant extracts and sunshine.

In the 19th century, there was
a great deal of research and interest in phototherapy. In particular, Niels
Ryberg Finsen, a Danish doctor, was awarded the Nobel Prize in Physiology or
Medicine in 1903 for his treatment of tuberculosis skin disease using solar
light in a systematic and scientific way. In recent years, phototherapy has
also been shown to reduce the inflammatory symptoms of many diseases by
affecting the immune system.
