Why Narrow Band?
UVB Narrow Band causes less sun
burning or erythemal effect than
other treatments such as UVB
Broadband. The chart above shows
that the skin's erythemal (sun
burning sensitivity) is at its max
at around 297 nm and that UVB NB
with it's spectra centered around
311-313 nm generates very low
erythemal response. This allows the
user to have longer treatment times
before "seeing" an erythemal
response. UVB NB is fast becoming
the recommended treatment to replace
Broadband UVB and PUVA. Most of
Amjo's sales today are UVB Narrow
Band units.
Clinical studies have shown that the
peak therapeutic effectiveness of
UVB to be between 295 to 313 nm and
that wavelengths below (shorter)
than roughly 300 nm are more likely
to cause a strong erythemal response
or severe burning. UVB Narrow Band
is in the 311-313 nm range and
causes less burning than shorter
wavelengths.
For Psoriasis:
Now dermatologists can gain the
advantage over persistent and
chronic cases of psoriasis with UVB
Narrow Band technology. Narrow Band
UVB has been shown to provide faster
clearing of psoriatic plaques when
compared to traditional Broad Band
UVB.
For Vitiligo:
Today UVB Narrow Band technology is
proving to be very useful in the
treatment of Vitiligo. It is
replacing traditional PUVA
phototherapy treatment. UVB Narrow
Band requires no photo-sensitizing
agents.
It is said that because the shorter
wavelengths are eliminated and that
exposure times can be increased. The
311-313 nm range is less than 1% of
the total range of wavelengths from
sunlight; it is a powerful and
targeted treatment. Narrow Band UVB
has proven to be the most effective
phototherapy treatment option for
thousands of psoriasis patients all
over the world. Now 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, further demonstrating that
it will become the phototherapy
treatment option of choice.
