Narrow Band Ultra Violet B Light is a relatively new technology on
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, the most
beneficial component of natural sunlight) while minimizing exposure to
superfluous UV radiation.
This allows patients to receive photo-therapy treatments with less
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 requires no
supplemental drugs.) These benefits have made Narrow Band UVB systems
increasingly popular with vitiligo patients and their doctors.
Even better is that Narrow B UVB light systems are available in
home-sized panel systems and cabinets, which many are finding far more
convenient than frequent trips to their dermatologist's office. Though
many people buy complete surrounding cabinets, some doctors suggest
that panels are actually more effective, and that the optimum distance
from the bulbs for the area being treated is about 7 inches. Time
exposures should be discussed with your dermatologist prior to using a
light panel or cabinet, as the exposure times vary greatly depending
on how long you have been treating, and your skin tone.
Narrow band UVB virtually eliminates superfluous and harmful UV by
emitting only 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.
