Photodynamic Therapy (PDT) is a treatment that involves a topical photosensitizing agent called Levulan activated with a specific wavelength of light. This treatment removes spots called actinic keratoses, which are precancerous skin changes that are caused by chronic sun exposure.You may require multiple treatments depending on the severity of the sun damage. Afterwards, you will also notice improvement in the appearance of uneven pigmentation and fine lines.
