PDT combines light and a light-activated drug to treat conditions like acne, psoriasis, and skin cancer.
What is it?
Photodynamic Therapy (PDT) can be helpful in treating a variety of skin conditions. PDT is a two-step process, starting with application of a light-sensitive drug, sometimes called a photosensitizing agent. This drug is inactive when applied. Applying a specific wavelength of light activates the drug, allowing for targeted treatment. This ability to target very specific areas helps protect healthy skin during treatment.
