Narrowband UVB Therapy Information and Instructions

Narrowband UVB Therapy Information (NBUVB)

Narrowband is a specific wavelength of ultraviolet light (311nm), one of the types of ultraviolet light in sunlight.  It works by reducing inflammatory cells that are over-active in various skin conditions.

UVB are short light waves that can cause redness or tenderness 8-24 hours after exposure.

It generally will take 10-12 or more treatments before skin improvement is noticeable, depending on the condition being treated.

General Guidelines

  • Narrowband therapy times will slowly increase, starting at about 60 seconds and increasing about 10% each visit.
  • You can expect your skin to tan, and occasionally burn, as we increase the dose.
  • Always skip a day between treatments.
  • Expose only your affected skin – cover the unaffected skin with sunscreen or clothing. (Apply sunscreens at home before coming for a treatment.)
  • If male genitalia are not involved, but the buttocks need to be exposed, hold a towel or a napkin over the genitalia. (Bring these from home).
  • Always wear UV protection goggles and underwear during treatment. Goggles will be provided and stored for you on-site. You will be charged a one-time fee of $10.00 for the goggles.
  • Response is slow – it will likely take at least 2-3 months before you notice much improvement.
  • Once a good response has been obtained, we will taper off your frequency and eventually stop treatments all together.
  • Do not apply prescription creams or moisturizers before light treatments, but do apply them afterward.
  • If you experience redness or tenderness after a treatment, do not come in for the next treatment until the skin returns to normal. ALWAYS REPORT redness or tenderness to the staff so your UV dosage can be adjusted. If you develop blistering after a treatment, phone our office and speak with a staff member for further instructions.
  • Some medication can make your skin more prone to burning. Report any new medications to the staff.
  • Increased skin wrinkling may be seen in the years following phototherapy, due to increased sun exposure. This is dependent on the amount of Narrowband therapy used.
  • Skin cancer rates have not been rising in the 50 years since starting Narrowband therapy medical use, but it is a theoretical risk, as you are getting more sunlight. This, too, is dependent on the amount of therapy required.
  • Please see your Dermatologist for regular follow-up visits to monitor your progress.
