What Is Narrow Band UVB?

Narrow Band Ultra Violet B Light is a relatively new technology for the vitiligo front. In the past, most doctors have used the PUVA system, which involved the use of Ultra Violet A light exposure and the taking of Psoralen pills. However, side effects for many people were unbearable. Narrow Band UVB light panels and cabinets solve the problems of over-exposure to ultraviolet by maximizing delivery of narrow-band UVB radiation (in the 311-312 nanometer range) while minimizing exposure to superfluous UV radiation.

The narrow band allows patients to receive photo-therapy treatments with lower risk of severe burning or pathogenic exposure to UV in harmful ranges. It also avoids the adverse side effects of the psoralens used in conventional PUVA therapy, since UVB treatment does not require that any medications be taken. These benefits have made Narrow Band UVB systems increasingly popular with vitiligo patients and their doctors. Even home systems are available, though home units should always be used under the care and monitoring of a physician。

Narrowband UVB lamps (NB-UVB) are available on all National Biological home Phototherapy units.

1 Narrow band UVB light treatment uses the optimal part of the UVB light spectrum which slows growth of psoriasis lesions or re-pigmentation of one's natural skin coloring.

2 Exposure time of narrowband UVB lamps can be longer than with traditional broadband UVB yielding more effective results. Recent studies have shown 75% clearing (PASI 75) with narrowband UVB.

3 Erythemal reaction is nearly eliminated with narrowband UVB light.

4 Risks and side effects of other treatments such as systemic drugs have not been found with narrowband UVB light therapy.

NB-UVB therapeutic advantages for your skin condition

Many experts have proved that Vitiligo - Narrowband UVB lights are useful in the treatment of Vitiligo. Narrowband UVB light treatment is replacing traditional PUVA phototherapy treatment. UVB narrowband lamps for vitiligo require no photo-sensitizing agents。

On the other hand,Narrow band UVB deadly eliminates surplus and harmful UV by emitting wavelengths of 311-312 nanometers. Conventional broad band UVB lamps emit a variety of wavelengths ranging from 280-330 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. The 311-312 range is considered by many to afford optimum safety.
