Photodynamic Therapy (PDT): What It Is and How It Works
Photodynamic therapy, or PDT, is a light‑based treatment that uses a special drug and a specific wavelength of light to destroy abnormal cells. The drug, called a photosensitizer, is applied to the skin or taken orally. After it settles into the target cells, a doctor shines a light that activates the drug, creating a reaction that kills the cells without major surgery.
When Doctors Recommend PDT
Doctors often turn to PDT for skin cancers like basal cell carcinoma and actinic keratosis, because it targets the growth while sparing healthy tissue. It’s also used for acne, psoriasis, and some lung or esophageal cancers when traditional surgery isn’t ideal. If you’ve tried creams or laser therapy without success, your dermatologist might suggest PDT as the next step.
What to Expect Before, During, and After Treatment
Before the session, you’ll meet the doctor for a quick exam. The photosensitizer may be a cream you apply at home, a gel the clinic puts on, or a pill you swallow. Some preparations require you to avoid bright light for 24‑48 hours because they make your skin extra sensitive.
During the appointment, the doctor shields the area with a protective cover and shines a non‑laser light source for a few minutes. You might feel a warm sensation, but it’s usually painless. The whole process often takes under an hour.
Afterward, the treated spot can turn red and feel like a mild sunburn. This is normal and typically fades in a week or two. You’ll be told to stay out of direct sunlight, wear sunscreen, and avoid tanning beds while the skin heals. If you notice severe swelling, blistering, or lasting pain, call your provider right away.
Cost varies by location and insurance coverage, but many plans handle part of the expense for FDA‑approved uses. Ask your clinic for a detailed quote before you start.
Overall, PDT offers a less invasive way to clear certain skin problems, with quick recovery and good cosmetic results. If you’re curious whether it fits your situation, schedule a consultation and ask about the photosensitizer type, light source, and after‑care plan that matches your skin type.
