Photodynamic therapy (PDT) is a non-invasive treatment involving light-sensitive medicine and a harmless light source. When exposed to the light, the medicine becomes activated, causing damage to nearby abnormal cells.
This technique is used to treat various conditions, including actinic keratoses, superficial skin cancer no melanoma and other skin-related issues such as warts, acne or nail fungus. PDT offers a minimally invasive alternative to more aggresive treatments, effectively targeting abnormal cells accessible to the light source (including daylight).

Frequently Asked Questions
Photodynamic therapy (PDT) is a minimally invasive treatment that uses a combination of light and a photosensitizing agent to destroy cancerous or diseased cells. The photosensitizing agent is a light-activated drug that accumulates in the target cells. When exposed to a specific wavelength of light, the photosensitizing agent generates reactive oxygen species (ROS) that damage the target cells.
PDT offers several potential benefits over traditional cancer treatments, such as surgery, chemotherapy, and radiation therapy:
- Non-invasive and minimally destructive: PDT does not involve surgery or incisions, and it typically causes minimal damage to healthy tissues surrounding the treatment area.
- Targeted treatment: PDT selectively targets cancerous or diseased cells, leaving healthy cells largely unaffected.
- Fewer side effects: PDT is generally associated with fewer side effects compared to traditional cancer treatments.
- Repeatability: PDT can be repeated multiple times if necessary without causing significant cumulative damage to healthy tissues.
PDT is used to treat a variety of conditions, including:
- Skin cancer: PDT is an effective treatment for various types of skin cancer, including actinic keratosis, basal cell carcinoma, and squamous cell carcinoma.
- Acne: PDT can be used to treat moderate to severe acne by reducing inflammation and destroying acne-causing bacteria.
- Sun damage: PDT can help reduce the appearance of wrinkles, fine lines, and age spots caused by sun damage.
- Precancerous lesions: PDT can be used to treat precancerous lesions, such as cervical intraepithelial neoplasia (CIN) and oral leukoplakia, to prevent them from progressing to cancer.
PDT is suitable for a wide range of individuals, including those with sensitive skin. However, it is important to consult with a qualified dermatologist or other healthcare provider to determine if PDT is right for you and to discuss your specific condition and treatment goals.
After PDT treatment, you may experience some mild side effects, such as redness, swelling, or a burning sensation. These side effects are typically temporary and subside within a few days. You may also notice an initial improvement in your condition, with more noticeable results developing gradually over time.
