Light therapy, that is, use of artificial or natural ultraviolet light is used to treat psoriasis.
Sunlight (Ultraviolet light) kills active T cells when the skin is exposed to it. This slows down the formation of skin cells and reduces inflammation and scaling. Care should be taken because intense exposure of ultraviolet light damage skin and worsen symptoms.
Ultraviolet B (broadband UVB) phototherapy in controlled doses may be used to treat mild to moderate symptoms of psoriasis. It's well suited to treat resistance psoriasis, single patches and widespread psoriasis. Moisturizer can then be used to decrease UVB side effects such as redness, dry and itchy skin.
Narrowband UVB therapy is a new treatment type of psoriasis and more effective than UVB (broadband) treatment. It's administered on the skin three times a week until the skin shows improvement and thereafter on weekly basis. However, it may cause severe burns on the skin.
Geockerman theraphy combines UVB and coal tar treatment. Coal tar enables good reception of UVB light into the skin making the combination more effective than the above types of psoriasis treatments.
Excimer laser involves use of a controlled UVB light beam and of a known wavelength, directed on the affected skin to control inflammation and scaling. Its side effects are blistering and redness.
