Photodynamic Therapy (PDT)

What is Photodynamic Therapy?

Photodynamic therapy (PDT) is a procedure that uses a photosensitizing drug to apply light therapy selectively to target pre-cancerous lesions on the skin, acne and sun damage.

Which areas can PDT treat?

PDT can help clear the skin of actinic keratoses which are premalignant growths in sun-exposed areas, mainly the face, chest, legs, arms, and hands.

What should I expect during my visit?

The skin will be cleansed thoroughly and the Levulan solution will be applied to the area. You will then be directed to wait the recommended time (1 to 3 hours) in order to allow the solution to penetrate to the targeted cells. The second part of your treatment includes illuminating your treated areas with the light.

Is there any down time after the treatment?

After the treatment, the skin involved will be extremely light sensitive for 48 hours until the medication is completely metabolized, so complete avoidance of sun exposure is necessary in the first 2 days post treatment. Most of the time, redness and mild peeling, similar to a severe sun burn-like reaction occurs over the first two to three days. Occasionally, there can be a burning discomfort for 24 hours and more prolonged peeling and redness lasting five to 14 days can occur.
