Targeted uv phototherapy 308-NM Excimer Lamp UVB phototherapy UV light for dermatological disorders for vitiligo

308-NM Excimer Lamp TS

The 308-nm excimer lamp represents the latest advance in the concept of selective totherapy, for Psoriasis and vitiligo attracting most attention.

Â

Induced rates of repigmentation seem to be higher than with narrowband UV-B. Moreover, the selectivity ofthetreatment prevents irradiation of healthy skin and limits unsightly tanning of surrounding skin.

Â

Introduction of the 308-nm excimer lamp

Â

The excimer lamp emits a wavelength of 308 nm produced using xenon and chlorine gases. These technical characteristics provide with many advantages over conventional totherapies. High fluencies are possible, which can be useful in thick plaques of psoriasis.

Â

It is also possible to selectively turn the beam of light and thus to treat the specific area involved, sparing healthy skin.

It is easier to reach areas that are usually difficult to treat, such as mucosa.

Â

The use of a monochromatic wavelength of 308 nm gives tobiological effects theoretically superior to those provided by NB-UVB,

Â

Stimulation of melanocyte migration and proliferation from progenitor niches located in hair follicles is certainly the major factor. This stimulation is due to the direct action of UV on melanocytes but also to the action of cytokines secreted by keratinocytes.

Â
