About Phototherapy
What is Phototherapy?
Phototherapy uses specific wavelengths of the sun's natural spectrum for the treatment of psoriasis.

What is the difference between UVB "Broadband"
and UVB "Narrowband"?

Conventional "Broadband" UVB lamps emit light in a broad spectrum that includes both the therapeutic wavelengths specific to the treatment of skin diseases plus the shorter wavelengths which can result for sunburn. Sunburn has a negative therapeutic benefit, increases the risk of skin cancer, and limits the amount of therapeutic UVB that can be taken. "Narrowband" UVB lamps, on the other hand, emit light over a very short range of wavelengths concentrated primarily in the therapeutic range. UVB Narrowband is therefore safer and more effective than conventional UVB Broadband.

Is narrowband Phototherapy safe?

Yes - Traditional phototherapy methods have been used for well over 25 years with very few side effects. Many common drugs on the market have known and proven side effects, and have only been in circulation for a few years and so there is little knowledge of long term side effects.
