Phototherapy or light therapy is a form of treatment for the skin by using the wavelength of artificial light from ultraviolet (blue light), part of the solar spectrum.


In this way, light of a certain wavelength can be delivered with a higher intensity. Phototherapy was first used in the treatment of psoriasis, eczema (eczema), vitiligo (pigment cells damaged causing white patches), lymphoma in the skin and some cases of itchy skin (mainly due to kidney or liver disease). However, phototherapy is not suitable for all forms of psoriasis and eczema. Phototherapy can even aggravate the disease.


There are two types of phototherapy, namely UVA and UVB. UVA phototherapy is usually given in conjunction with a light sensitivity tablet called psoralen (PUVA therapy). UVA is part of the UV spectrum associated with pigmentation. UVB is the most common type of phototherapy. UVB is the most beneficial part of sunlight to treat skin diseases.
