Photodynamic Therapy

Blu-U photodynamic therapy (PDT) is a cutting-edge treatment that uses a combination of light-sensitizing medication and advanced blue light to target abnormal or precancerous cells in the skin. The process begins with the application of a medication called Levulan, which gets absorbed by the abnormal cells.

After an activation period of 1 to 2 hours (or sometimes overnight), your provider applies blue light to the treatment areas for precisely 16 minutes and 40 seconds. This light triggers a chemical reaction that destroys the abnormal cells while leaving healthy tissue intact. With Blu-U phototherapy, you can achieve clearer skin with minimal discomfort.

Levulan PDT is a form of photodynamic therapy (PDT) that we use to treat actinic keratosis (precancer) and basal cell carcinoma (cancer). Photodynamic therapy uses a light-sensitizing drug and a special light to treat abnormal cells. Levulan PDT is extremely useful for the treatment of multiple lesions on the scalp and face. PDT is non-invasive and causes little to no scarring. Levulan is the brand name for the type of medication (aminolevulinic acid) that is used during the procedure.

Patients typically notice smoother, clearer skin and reduced lesions within a few weeks of treatment. Blu-U PDT offers a host of advantages that make it a preferred choice for many patients.

Key benefits of phototherapy:

Noninvasive Treatment: Blu-U PDT can eliminate the need for surgical procedures, making it a more comfortable option with minimal downtime. This means you can return to your daily activities sooner, without the disruption of extensive recovery periods.

Targeted Results: This therapy precisely targets abnormal cells while sparing surrounding healthy tissues, ensuring focused treatment without unnecessary damage. The result is safer and more effective care for your skin concerns.

No Scarring: Unlike traditional surgical methods, Blu-U phototherapy leaves little to no evidence the treatment was ever performed. It’s great for preserving your skin’s natural appearance and boosting your confidence.

Improved Skin Health: By addressing precancerous cells and sun damage early, Blu-U phototherapy reduces the risk of progression to more serious conditions. This proactive approach enhances both the look and health of your skin.

We can perform treatments from our offices in Dover & Londonderry, New Hampshire. Patients MUST avoid sunlight and bright indoor lighting for 48 hours. Sunscreen will not protect the treated skin, so remember to cover up your skin. You may feel pain, stinging or burning during the light portion. These sensations can last for several hours or a couple of days after the treatment. Patients are asked to bring a hat that will cover areas to be treated on face, ears, scalp and/or neck.

While Levulan PDT treatments are very effective, there is a chance that you will need to continue to need periodic treatments for actinic keratoses, depending on your skin. Some skin actinic keratoses are more aggressive than others and will need additional treatments and closer follow-ups. Sun-damaged skin frequently needs follow-up and further treatments. Other procedures may be needed to fully treat your lesions. We will schedule follow-up appointments with you for the first few years after your photodynamic therapy, usually every 4-6 months. If you have a history of skin cancer, annual skin checks are a great way to stay ahead of melanoma and basal cell carcinoma.
