“A regular skin checkup can literally save your life.” Jennifer Krasnoff, MD

UVB (ultraviolet B light) is the most common form of phototherapy used to treat various skin diseases including psoriasis, vitiligo, eczema, itching, and disorders including striae alba and hypopigmented scars. 308-nm Laser Phototherapy is an advanced form of UVB phototherapy that delivers targeted, high-dose, monochromatic therapeutic light directly to affected tissue without exposing healthy skin.
The 308-nm Phototherapy Laser creates a concentrated, but painless, beam of light that is applied through a handpiece directly to the skin. By targeting only the affected tissue without exposing healthy skin, the laser delivers high-dose treatment that may promote faster clearing and longer remission than conventional UVB phototherapy. While treatment times vary, most sessions for diseases last about 5 to 25 minutes and sessions for striae and scars take 1 to 2 minutes.

This treatment is NOT A CURE, but 308-nm UVB laser phototherapy may effectively control or improve your disease or disorder. Patients have used this treatment successfully for many years and often are able to maintain clearance of improved skin over extended periods of time, often 6 months or more. Occasionally, maintenance treatments may be recommended to sustain disease clearing or cosmetic repigmentation.

Each condition and patient will vary in the number of treatments needed and the time it will take to reach clearing. Most patients initially require 2 treatments each week to clear their lesions. It may take 12 to 15 treatments to improve psoriasis and cosmetic conditions and 15 to 30 treatments to improve vitiligo. Not all patients will clear completely. Many patients go into remission and may then stop treatments.

The expected benefits of 308-nm UVB laser phototherapy are:

  • Improvement of existing lesions and hypopigmented areas
  • Reduction of new lesions
  • Remission - in many cases 308-nm UVB laser phototherapy has resulted in a near total clearing of the disease process. The duration of this remission varies with each patient. Maintenance therapy may be required.

Risks and side-effects of phototherapy:

  • The most common side effect of this therapy is UVB-induced sunburn, which tends to be mild and short-lived. This may occur at any time during therapy. Certain drugs may also cause you to get a sunburn. Please let your doctor/nurse know of any medications you are taking, or any that you begin while undergoing therapy. If sunburns occur, antibiotic ointment or steroid cream may be used after treatment.
  • Other possible but rare side effects include blistering and hyperpigmentation, which tend to be mild and short-lived. If blistering occurs, antibiotic ointment or steroid creams may be used after treatment.
  • It is possible with any form of UV light that an increased incidence of skin cancer may occur later in some patients, usually only with many UV light treatments over extended areas of skin. The targeted nature of 308-nm UVB laser phototherapy, short treatment time, and the low number of treatments may reduce this risk.
  • UV treatments may cause dryness and itching.
  • UV treatments age the skin over time and may increase freckles and pigmentation of the skin. The targeted nature of 308-nm UVB laser phototherapy, short treatment time, and the low number of treatments may reduce this risk.
  • Ultraviolet rays may damage the eyes and increase your risk of cataracts. This is preventable with protective eye goggles worn during treatment. These will be given to you and are required for treatment.
  • UV light may cause exacerbation of other medical conditions such as lupus erythematosus that have sensitivity to UV wavelength.

I have fully read and fully understand the above information regarding 308-nm UVB laser phototherapy. I also understand that no one completely knows the long-term effects of UVB phototherapy including 308-nm UVB laser phototherapy. I realize that these treatments do not cure my skin disorder and that I may need maintenance therapy. My practitioner has explained the nature, purpose, and expected benefits of 308-nm UVB laser phototherapy, as well as the risks. I have also been presented with the alternative treatments and their potential risk. My questions were answered regarding the procedure. I authorize my doctor (above) to prescribe light therapy.
This authorization extends to his/her associates, including other physicians and assistants selected by him/her, to carry out phototherapy. I understand that I am free to withdraw my consent and stop treatment at any time.

Additionally, I consent to be photographed before, during, and after the laser phototherapy; that these photographs shall be the property of the above doctors and may be used as they deem proper for scientific and educational purposes.
