Photodynamic Therapy

PDT is a medical treatment for severe actinic damage and pre-cancerous lesions, such as actinic keratosis.  An ALA cream (Aminolevulinic acid) is applied to the skin which is activated by LED light that selectively destroys cancerous cells.  A consultation is advised prior to procedure.

It can also be used for sun damage and rejuvenates skin texture and appearance.


After the treatment one must avoid sunlight and other intense light sources completely for 48 hours. The majority of people will have mild redness and minimal discomfort but about 5% will experience a “sunburn” like reaction in which they are uncomfortable for 24 hours and the skin looks red and peeled for 2-3 days.
