PHAROS excimer lasers are xenon chloride (XeCl) lasers that deliver concentrated, but painless, high-dose monochromatic 308nm UVB phototherapy directly to psoriatic and depigmented lesions without exposing surrounding healthy tissue.  Unlike conventional UVB systems that emit wavelengths from 290 to 320nm, PHAROS excimer lasers deliver only monochromatic 308nm, clinically proven the most efficacious wavelength for treating psoriasis, vitiligo, atopic dermatitis, and leukoderma. Continuously adjustable from 3.24 cm2 to 2 mm round with constance fluence, PHAROS' infinitely variable spot size handpiece and aiming beam allow precise target treatment of affected tissue quickly, easily, and accurately without collateral damage to healthy skin.  By enabling physicians to precisely target only affected skin cells, PHAROS excimer lasers safely deliver higher treating dosages than are possible using conventional UVB or PUVA. 

For patients, this means short treatment times of 5-7 minutes for up to 10% body surface area.

It also means that psoriasis patients may need only 6 to 10 treatments, rather than 30 or more conventional UVB or PUVA sessions. 

Moreover, while each patient is unique, psoriasis patients may enjoy several months treatment-free remission after completing 6 to 10 laser sessions.

For vitiligo patients, repigmentation often begins after as few as 6 sessions.  While the degree and speed of repigmentation is greatly effected by the anatomical location of the disease, most treatment regimens consist of 15 to 30 sessions on a twice or thrice-weekly schedule. 

For both psoriasis and vitiligo patients, these positive patient outcomes after very few treatments encourage patient compliance and enhance satisfaction.
