Narrowband UVB – now considered the gold standard of treatment for vitiligo covering more than 20% of the body. Narrowband UVB (NB) uses the portion of the UVB spectrum from 311-312 nm. This region has been determined to help stimulate pigment cells to produce melanocytes in less time than it takes to burn the skin. NB can be used on children old enough to stand still and keep goggles on. Only full sized body units provide the immune suppression needed for stabilization that may halt further pigment loss, as the handheld units only treat isolated areas. Eye protection is worn during treatment to protect the eyes, but isn’t necessary once the treatment is over.” VSI website

“Present in natural sunlight, UVB is an effective treatment for psoriasis. UVB penetrates the skin and slows the growth of affected skin cells. Treatment involves exposing the skin to an artificial UVB light source for a set length of time on a regular schedule. This treatment is administered in a medical setting or at home.

Several studies indicate that narrow-band UVB clears psoriasis faster and produces longer remissions than broad-band UVB, and can be combined with other topical and/or systemic agents to enhance efficacy… Combining UVB with systemic therapies may increase efficacy dramatically and allow for lower doses of the systemic medication to be used.” NPF website

“Phototherapy is used for widespread eczema or for localized eczema (such as hands and feet) that is unresponsive to topical treatments. For some, it can be a way to avoid using systemic treatments such as cyclosporine or methotrexate. The phototherapy machines used by doctors emit UVB light at 311-312 nm range, which is the most beneficial portion of natural sunlight for skin diseases. It also avoids the UVA aspect of sunlight which is very damaging to skin.” NEA website
