• Schedule appointments 2-3 times weekly with at least 48 hours between sessions.
  • The XTRAC laser works best for areas of vitiligo on the face, neck, and upper chest.
  • Hands, feet, fingers, and toes typically do not respond as well as other areas of the body to UVB phototherapy.
  • Repigmentation of treated areas may take 30 or more treatment sessions depending on individual response to UVB light.
  • Moderate skin tenderness (similar to a mild sunburn) lasting 24-72 hours indicates a good therapeutic response to the XTRAC laser treatment.
  • Once repigmentation of treated areas is achieved, results may be permanent.


  • Blistering is a normal side effect of XTRAC therapy and may occur on treated areas.
  • Hyperpigmentation (tan spots) may develop and will fade over time once therapy is complete.


  • Skin should be clean and dry when you arrive for your appointment.
  • Do not apply creams, lotions or medications.
  • Review all areas of vitiligo with the clinician.
  • Review all side effects of prior treatments with the clinician.
  • Wear protective eyewear provided by the XTRAC clinician.


  • Schedule next appointment before leaving the office.
  • Treat your skin as you usually would and apply any medications, creams, lotions, etc. freely.
  • Keep treated areas free from excessive sun exposure between treatment sessions.
