latest advance in the concept of selective phototherapy, for Psoriasis and vitiligo 

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

MANY STUDIES HAVE EVALUATED THIS NEW DEVICE IN A NUBER OF DERMATOLOGIC DISORDERS.

Advantages of the 308-nm excimer lamp

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

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.

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

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.

Monochromatic beam of lighting, consistent high fluencies, reducing treatment sessions and cycles.

Selectively treat a lesion while sparing surrounding healthy skin, with the specific treatment handler.
