HI-Light Pilot Trial for Vitiligo: Hand Held NB-UVB for Early or Focal Vitiligo at Home

"Narrowband UVB is now the most common form of phototherapy used to treat skin diseases. Narrow-band refers to a specific wavelength of ultraviolet (UV) radiation, 311 to 312 nm. Hospital NB-UVB usually involves whole body cabinets suitable for extensive, generalised vitiligo i.e. large or multiple lesions. Usually the whole body is exposed to the UVB for a short time (seconds to minutes). NB-UVB is also used in the treatment of many other skin conditions including psoriasis and eczema.~Hand held phototherapy units use the same lamp as the whole body units (TLO1) but only suitable for the treatment of smaller areas of skin i.e. early and focal lesions of vitiligo.~Early reports showed that these units are also safe and effective for the treatment of psoriasis of the scalp."
