What is a typical skin PDT session like?

You may be given a written procedure consent form to read and sign before your first treatment. The medical staff may take some pretreatment photography prior to applying the photosensitizer medication.

In the treatment room, you may be sitting or comfortably lying back on a table. Often a thorough cleansing of the face is done using alcohol and or acetone to degrease the skin. The less oil on the skin, the more readily the skin will absorb the applied topical medication.

The photosensitizer liquid or cream is applied topically to the whole area being treated (such as the entire face, scalp, back of the hands, back part of the forearms, legs, feet, scalp, chest, or back).

The medication is allowed to air dry for a few minutes, and then you will wait anywhere from 30-60 minutes for the incubation time. Some areas such as chest, back, and particularly forearms and legs require longer incubation times of two to 18 hours for better results. No two people or skin on different areas of the body are exactly alike. PDT requires physician adjustments for specific individualized incubation times and treatment durations.

After the proper incubation time, you are brought back into the light-source room where the medication is activated with a specific wavelength light source. There may be sensations of warmth, tingling, heat, or burning in some patients. A fan can be used to help cool off during the treatment. The treatment area is then washed off and sunscreen applied. Instructions are given on how to care for the skin at home.
