Narrow Band UVB


Narrow Band UVB has proven to be the most effective phototherapy treatment option for thousands of psoriasis patients all over the world.

With more research being done every day on conditions such as eczema, vitiligo, and mycosis fungoides, Narrow Band UVB continues to show its versatility with its promising results.

Why Narrow Band UVB is different

  • Conventional broad band UVB lamps emit a variety of wavelengths ranging from 280-330 nm.
  • Narrow Band UVB virtually eliminates superfluous and harmful UV by emitting only wavelengths 311-312 nm.
  • Clinical studies show the peak therapeutic effectiveness of UVB to be within the range of 295-313 nm, but wavelengths below 300 nm can cause erythema or severe burning and increase the risk of skin cancer.

Benefits of Narrow Band Phototherapy

  • Eliminating UV in wavelengths below 311 nm permits higher intensities and longer exposure times, so patients can derive the maximum benefit from phototherapy.
  • This increased effectiveness permits more aggressive treatment regimens, resulting in a shorter course of treatment. Extensive research* confirms that patients not only avoid the danger of serious burning from sub-erythemal exposure, they may also enjoy longer remission periods after treatment. Remission periods are similar to those with PUVA therapy and markedly superior to broad band UVB treatment. Studies show 38-40 percent of narrow band treated patients require no additional therapy for at least 12 months.
