Treating Psoriasis With Narrow Band UVB
What is UV Radiation?
UV radiation is part of the light spectrum that reaches the earth from the sun. It contains wavelengths shorter than visible light, making them unseen to the naked eye. Classified as UVA, UVB, or UVC, these waves are divided into two wave ranges, UVA I, which are 340-400 nanometers (nm, or billionths of a meter), and UVA II which are 320-340 nanometers. UVB measures from 290 to 320 nm. Most UVC does not reach the earth because the ozone absorbs its shorter rays before it reaches earth.
UVB Phototherapy as a Treatment for Psoriasis
Not all UV radiation is harmful. Some offer a great benefit to the treatment of the skin. Because our dermatology office uses narrow band UVB, the elimination of harmful and unessential elements allows its therapeutic benefit to treat the affected skin. Narrow band UVB uses wavelengths of 311-312 nm. UVB is present in natural sunlight, and is an effective treatment for psoriasis.
Different Types of UVB Phototherapy and Why Narrow Band UVB Treatment is Preferred
Two types of UVB treatment are commonly used, broad band and narrow band. The difference between them is that narrow band UVB light release a smaller range of ultraviolet light. Studies indicate that narrow-band UVB clears psoriasis faster and patients remain in remission longer than those treated with broad-band UVB do. In addition, there is the possibility of fewer treatments.
Treatment Expectations Following Your Dermatologist Visit
Narrow band UVB treatment limits the exposure of the skin and decreases the chance for burning and irritation. Limited exposure to the UVB wavelengths also reduces the risk of skin cancer. Before improving, a patient’s psoriasis may temporarily worsen during the course of treatment. As treatment continues, the symptoms will resolve and the patient will have a good outcome.
UVB enters affected skin and slows the growth of damaged skin cells. To treat skin conditions such as psoriasis, we expose the area to an artificial UVB source for a specified time on a regular schedule.
