In brief: Light therapy

Depending on the type and extent of your psoriasis, your doctor may recommend that you have ultraviolet (UV) light therapy.



You have the light therapy in a machine that looks similar to a shower cubicle, containing fluorescent tubes.
• Ultraviolet B (UVB) light therapy involves shining artificial UVB light on to your skin. UVB light occurs naturally in sunlight. You will usually have the therapy two to three times a week for up to eight weeks.
• Sometimes UVB light therapy is used in combination with topical treatments such as coal tar preparations. This combination may be effective at helping to control your symptoms by making your skin more sensitive to UVB light.
• Psoralen and UVA light therapy (PUVA) involves combining a medicine (psoralen) that sensitises your skin to sunlight with a controlled dose of UVA light. You may have psoralen as a tablet or applied directly to your skin. You usually have the treatment twice a week for up to 10 weeks.
