What is PDT?

PDT uses a light source and an activating medication (a drug that starts to work in the presence of light) to destroy abnormal skin cells.

What does PDT involve?

PDT takes place in three stages:

Stage one

Your Integrated Dermatology of NJ provider applies a light-sensitizing cream or liquid to your skin.

Stage two

The second stage is an incubation period that lasts 2-3 hours.

Stage three

Your provider exposes the treated skin to a specific light wavelength that activates the photosensitizing substance.

This process produces activated oxygen molecules that destroy the abnormal cells in the target area.

What conditions can PDT treat?

One of photodynamic therapy’s main uses is treating superficial skin lesions (actinic keratoses).

Actinic keratoses are rough lesions that most often form on your scalp, face, the backs of your hands, ears, the back of your forearms, neck, and shoulders. They usually affect older people after years of exposure to the sun. An actinic keratosis increases your risk of developing squamous cell carcinoma, so PDT treatment and monitoring the lesions is essential.
