UVB narrow band phototherapyt

UVB Narrow Band - The Gold Standard

--------------------------------------------------------------------------------
UVB Narrowband Technology

UVB Narrowband is not a panacea but it perhaps comes close when one is talking about Ultraviolet Phototherapy. Here at Amjo 95% of our sales are now UVB NB (Narrow Band or UVB 311). PUVA and UVB Broadband are almost non-existent in our world.

UVB Narrow Band sometimes called UVB 311 is a subset of the UVB Wideband or Broadband spectrum. The UVB band comprises the range of wavelengths between 290 nm and 320 nm while UVB Narrowband is a "narrow band" of wavelengths centered at roughly 311 nm..

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 our sales today are UVB Narrow Band.

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.

One can find UVB Narrow Band Bulbs in the following systems:

The Dermalight 80 or Handisol NB - Hand Held Wand

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.

Today, our sales are primarily UVB Narrow Band. Many people undergoing PUVA treatment enjoy the switch as they no longer need the concurrent drug therapy which for some causes nausea and other challenges.
