Photodynamic therapy consists of three steps, which begins with the application of a light-sensitizing cream. The second step of the process is incubation, which can take several hours. Finally, the damaged tissue will be exposed to a specific wavelength of light designed to activate the photosensitizing medication.

The procedure can be done either in a doctor’s office or in an outpatient setting. The doctors at U.S. Dermatology Partners can provide you with more information based on your individual needs.

Are There Side Effects to Photodynamic Therapy?

It is common to have redness and scaliness, similar to having a sunburn, after the treatment. This may last for a day or more than a week, depending on the amount of treatment. It’s important to follow your doctor’s protocol for sun exposure before, during and after the treatment.

How Long Will Photodynamic Therapy Last?

Annual maintenance treatments are generally required to maintain the protection, but individual maintenance requirements will vary with your specific condition.
