UVB Phototherapy has become one of the most frequently used treatments for psoriasis and a wide range of skin diseases, including atopic dermatitis, vitiligo, early stages of mycosis fungoides, and pruritic disorders.
Phototherapy or light therapy is a prescription treatment that is typically prescribed by a dermatologist. Phototherapy involves exposing the skin to ultraviolet light on a regular basis and under medical supervision. Treatments are done in a doctor's office or psoriasis clinic or at home with a phototherapy unit. The key to success with light therapy is consistency.
Ultraviolet B (UVB) which is present in natural sunlight, is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells. Treatment involves exposing the skin to an artificial UVB light source for a set length of time on a regular schedule. This treatment is administered in a doctor's office or clinic or at home with a phototherapy unit.
UVB treatment is offered in different ways. This can include small units for localized areas such as the hands and feet and full-body units. Patients attend for phototherapy two to four times weekly. If whole-body treatment is recommended, the patient is placed in a specially designed cabinet containing fluorescent light tubes. The amount of UV is carefully monitored by the phototherapy staff. A number of protocols exist depending on the individual's skin type, age, skin condition and other factors.

Is this treatment appropriate for my skin type?
While people with moderate to severe psoriasis can benefit from light therapy, each person's skin reacts to phototherapy differently, both in how much improvement they see in their psoriasis symptoms and in how long those benefits last. People with photosensitivity issues should avoid light therapy, as should people with a history of skin cancers, lupus, and pregnant women.
Are there any risks associated with this treatment?
Occasionaly a sunburn of the skin can occur. However multiple long term studdies of narrow broadband UVB therapy have not shown any increase in skin cancer.
How often will I need this treatment?
People usually undergo 3 - 5 light therapy sessions per week over the course of 2–3 months. People usually see an improvement in 2–4 weeks, depending on the type of light therapy. The average remission time is 3–12 months.
Do I need to do anything pre-treatment?
- Moisturize your skin regularly, especially right before light therapy.
- Avoid any photosensitising medications prior to therapy.
