Photodynamic Therapy


Photodynamic Therapy (PDT) is a multi-use light activated system for destroying abnormal cells (pre-cancers such as Actinic Keratoses) and also for addressing overactive sebaceous glands, which are a root cause of acne. 

 

Treating Pre-Cancers with PDT

To start we will apply a topical photosensitizing solution to the affected area about one hour prior to treatment. Unhealthy skin cells absorb the topical photosensitizer, while healthy ones do not. Next we apply the light which activates the topical medication, killing the damaged cells - both the visible ones and those that are microscopic and not yet visible. Once the solution has been absorbed by the targeted area, the light is used to activate the photosensitizing solution, which destroys acne cells and shrinks the sebaceous glands which are producing the excess oil. A treatment plan will be customized based on your individual needs, typically patients need 1-3 treatments at 2-4 week intervals.

You can expect mild discomfort (stinging sensation) when the photosensitizing solution is applied and during the laser pulses. After the treatment your skin will appear red (for 2-3 days). You will need to stay out of the sun for 48 hours. On day 3 the skin may feel tight and begin to peel.
