Excimer Laser Therapy (XTRAC)

Psoriasis Treatment

XTRAC is the only FDA-cleared, clinically-proven excimer laser that clears the skin of psoriasis—and it works fast, with many patients seeing significant improvement and long-lasting results. Because XTRAC delivers a highly targeted, therapeutic beam of UVB light only to areas of the skin affected by psoriasis, healthy skin surrounding the lesions is unaffected.

XTRAC clears the symptoms, prolongs the results, and returns skin to a clinically healthy state, all in record time. With consistently predictable results, patients experience more good days than bad days.

Quick Facts:

  • Effective treatment—symptoms reduced generally in 10-12 treatment sessions
  • Simple, painless treatment—sessions are very short
  • Relief without messy creams and daily skin care regimen
  • Covered by many insurance plans

Vitiligo Treatment

XTRAC treatments can minimize and, in many cases, even get rid of vitiligo depigmented patches. The XTRAC excimer laser delivers a targeted beam of UVB light and only the areas of skin affected by vitiligo receive the laser energy.

Though the laser spot size measures only 18mm x 18mm, due to rapid exposure times, relatively large, discrete areas can be treated in just 5 to 10 minutes, which is much quicker than the duration of conventional phototherapy light sessions. Most importantly, patients receiving XTRAC treatments achieve complete response rates faster than other lasers.
