Photodynamic Therapy (PDT)

Photodynamic Therapy, or PDT, uses light energy and a topical photosensitizing agent called Levulan to remove sun damaged and pre-cancerous areas of the skin. This treatment can also be used to improve the appearance of fine lines and skin pigmentation, as well as skin affected by acne. Sun damaged and pre-cancerous areas, referred to as actinic keratoses (AK’s), can be reduced by 70 percent after one treatment with PDT. More stubborn areas of AK can be treated again at a later date with the aim of complete eradication. The PDT procedure involves the application of Levulan (containing aminolevulonic acid, or ALA) to the treatment areas. A blue light is then shown over the damaged areas of skin, activating the ALA and helping it to fight off skin abnormalities. The treatment typically feels like the snapping of a rubber band against the skin – any discomfort can be alleviated with ice packs and a cooling fan used during the procedure. The entire treatment usually takes less than 30 minutes. Skin conditions like acne and signs of aging may require a series of treatments spaced over a few weeks to achieve optimal results.

You will likely experience redness and irritation in the treated areas following the procedure, and your skin will peel for several days after treatment. You may also be extremely sensitive to light in the treated areas for the first few days after PDT. Our doctor will discuss all aspects of treatment with you at your initial consultation, and help you determine if PDT is the best option for your needs.
