Treasure Valley Dermatology is proud to offer phototherapy for the treatment of many types of skin
disease. Phototherapy can be an effective way to treat psoriasis, atopic dermatitis (eczema), pruritis
(itching), vitiligo, and others. Phototherapy uses a specific wavelength of light called narrowband
ultraviolet B (NBUVB) to treat the skin.
What is ultraviolet B radiation (UVB)?
Ultraviolet (UV) rays are produced by the sun. Although they can’t be seen, they are an important part
of sunlight and are grouped into different wavelengths: UVA, UVB and UVC.
- UVA rays penetrate skin and cause it to darken or tan.
- UVB rays are mostly absorbed by the epidermis, which is the top layer of our skin and is responsible
- UVC rays are absorbed by the Earth's ozone layer, so they do not reach us.
A specific wavelength of UVB (311 to 312nm) thought to the most useful range for treating many
skin conditions. This is referred to as narrowband UVB, Treatment with UV light is often referred to as
What can narrowband UVB treat?
Narrowband UVB is the administration of ultraviolet light to treat various inflammatory skin diseases
including but not limited to psoriasis, eczema, vitiligo, and itching (pruritus).
What does treatment involve?
Specially trained nurses administer the treatment at the clinic. Patients step into a device that
resembles an upright tanning bed. However, this light will not make you develop a “tan”. Patients will
expose their affected skin to the light for a few seconds to a couple of minutes. Over a period of a few
weeks, patients can see significant improvement in many of the skin problems described above without
exposing the body to drugs that go inside the body and have the potential to cause side effects.
Treatments are repeated 2 or 3 times per week over several months. Patients may feel a warm sensation
during treatment, but it does not hurt.
Why should I have narrowband UVB treatment?
This treatment should help to improve your skin condition. It is often recommended if you have tried
creams without success. It is often used in combination with other treatments. Compared to other forms
of phototherapy, narrowband UVB has the following benefits:
- For many conditions, you are more likely to have longer periods where your skin condition disappears
or improves with narrowband UVB than with broadband UVB.
- For many (though not all) conditions, narrowband UVB is as effective as PUVA radiation), but with
fewer side effects.
- Risk of skin cancer has been shown to be significantly less with narrowband UVB phototherapy than
with other types of phototherapy or with natural sun exposure.
