PDT (Photodynamic Therapy) is a procedure that is used to treat precancerous and cancerous skin lesions as well as to improve dull, sun damaged skin and active acne. It treats the skin cancer without leaving any scars.


  • Works on all skin types
  • Very safe and no scarring
  • Therapeutic and cosmetic improvement

How it works

A clear solution called Levulan is applied to the skin surface and left on anywhere from 1 to 4 hours. The prescribing doctor will determine the precise time. Then the Levulan is activated by our special LED light therapy for about 20 minutes.

What to expect

Your visit to Vancouver Laser for PDT will take anywhere from 2 – 5 hours depending on your incubation time.


You will have approximately 48 hours of redness that resembles a sunburn. Cold vinegar compresses can be applied for comfort. After 48 hours the redness will start to subside and the abnormal cells will gradual peel and slough off over the next few days. A light exfoliation can be done on day 5 to smooth the skin.

Recommended sessions

1 treatment every month until any questionable skin lesions have cleared up with annual maintenance if you are at a high risk for skin cancers.

Possible downtime

  • Redness for two days with the dull cells turning brown and exfoliating over the next 5 days

Post treatment care

  • Avoid sun exposure and make up application for 3 days post treatment. Any sun exposure should be done with an SPF 50 or more
