Also known as blue light treatment, PDT uses a substance called photosensitizer together with a particular wavelength of light to destroy unwanted cells.
This revolutionary, corrective procedure involves close-range exposure to fluorescent blue light. PDT Therapy cancels out some of the negative effects that the sun has had on the face by killing off abnormal cells that can potentially lead to cancer.
Depending where on the body you get PDT Therapy, it may be somewhat painful. But the good news is that patients are often given a nerve block to minimize discomfort during the procedure. Research shows this has a major impact on how satisfied patients are with the results.
If this procedure addresses sun damage on the face, the most common side effects are temporary swelling and skin discoloration. You may also experience nausea, hiccups, or temporary difficulty swallowing if you get PDT Therapy on or near the throat. All of these minor symptoms are expected to go away in a few days.
Your skin will remain sensitive to light in the 48 hours following the procedure. So you should stay out of the sun and wear protective clothing (hat, glasses, and a long-sleeved shirt) if you must go outside. The results of PDT Therapy are long-lasting if you remain diligent about minimizing your sun exposure and wearing sunscreen daily.
