Understanding Photodynamic Therapy (PDT)
Photodynamic Therapy (PDT) is a non-invasive treatment that combines a photosensitizing medication with specific wavelengths of light to target abnormal or damaged skin cells. PDT is highly effective in addressing:
Precancerous Lesions (Actinic Keratoses): Early treatment of sun-damaged skin to prevent progression to skin cancer.
Acne: Reduces inflammation, eliminates acne-causing bacteria, and decreases oil production.
Sun-Damaged Skin: Improves skin texture, discoloration, and overall health.
How Blue Light PDT Works
Photosensitizer Application: A light-sensitive medication, such as Levulan® (aminolevulinic acid), is applied to the affected area. These photosensitizers are absorbed by abnormal cells.
Incubation Period: The photosensitizer is left on the skin for 30–90 minutes to allow full absorption.
Blue Light Activation: The treated area is exposed to blue light, which activates the medication. This triggers a chemical reaction that destroys abnormal cells.
Healing Process: Over the next 7–10 days, damaged skin cells flake or crust, revealing healthier skin underneath.
Follow Up: You will need a second treatment after 30+ days for blue light PDT to work properly.
What to Expect from Blue Light PDT
Before Your Treatment
Avoid retinoids, glycolic acids, and prolonged sun exposure for at least 48 hours.
Arrive with clean skin, free from makeup, lotions, or sunscreen.
During Your Treatment
The photosensitizer is applied to the target area and allowed to incubate.
Blue light exposure lasts about 15–20 minutes. Protective eyewear may be provided, and most patients report mild tingling or warmth during treatment.
After Your Treatment
Treated areas may appear red or feel like a mild sunburn for 1–2 days.
Skin will flake or crust over the following week as damaged cells are cleared.
Avoid direct sunlight for 48 hours and apply broad-spectrum sunscreen (SPF 30 or higher) regularly.
You will need to schedule a follow up appointment for a second treatment 30 or more days after the original treatment.

Frequently Asked Questions
What is Photodynamic Therapy (PDT) with blue light?
Photodynamic Therapy (PDT) with blue light is a non-invasive treatment that combines a photosensitizing medication with blue light to target and destroy abnormal skin cells. It is commonly used to treat conditions like actinic keratoses, acne, and sun-damaged skin.
How does blue light therapy work for precancerous lesions like actinic keratoses?
Blue light therapy works by applying a photosensitizing medication, such as Levulan or Ameluz, to the affected area. The medication is absorbed by abnormal cells. When activated by blue light, it creates a chemical reaction that destroys precancerous cells while sparing healthy tissue.
What is the difference between blue light and red light PDT?
Blue light targets surface-level conditions like actinic keratoses and acne due to its shorter wavelength (400–490 nm). Red light penetrates deeper into the skin and is used for thicker lesions or inflammatory conditions. At Rixis Dermatology, we offer blue light PDT to address surface-level skin conditions effectively.
Is blue light PDT painful or uncomfortable?
Most patients experience mild tingling, warmth, or a stinging sensation during light exposure. This discomfort is generally well-tolerated and subsides shortly after the session.
What should I expect during a blue light PDT session?
During your session, a photosensitizing agent is applied to the affected area and allowed to absorb for 30–90 minutes. The area is then exposed to blue light for 15–20 minutes. Protective eyewear will be provided, and the entire process is conducted in a comfortable clinical setting.
How long does it take to recover from blue light PDT?
Recovery typically takes 7–10 days. The treated area may appear red, swollen, or flaky, similar to a mild sunburn. These effects gradually improve, revealing healthier skin underneath.
Why do I need to avoid sunlight after blue light therapy?
The photosensitizing medication used in PDT increases your skin’s sensitivity to light. Avoiding sunlight for at least 48 hours post-treatment helps prevent severe sunburn or irritation.
How many sessions of blue light PDT are typically needed?
For precancerous lesions like actinic keratoses, 2 sessions are usually sufficient. For acne treatment, multiple sessions may be recommended to achieve optimal results. Your dermatologist will determine the number of sessions needed based on your condition.
Does insurance cover blue light PDT for actinic keratoses or acne?
PDT for precancerous lesions like actinic keratoses is often covered by insurance. However, coverage for acne treatment may vary. Contact your insurance provider or our office to verify coverage for your specific case.
Can blue light therapy help prevent skin cancer?
Yes, blue light PDT is effective in treating actinic keratoses, a precancerous condition caused by sun damage. By targeting and eliminating these abnormal cells early, PDT reduces the risk of progression to skin cancer.
