Photodynamic Therapy (PDT) Edmonton

Effectively treat skin conditions and early-stage cancers with specialized photodynamic therapy (PDT) in Edmonton. Our expert dermatologists use this advanced, light-activated treatment to target and eliminate abnormal cells, promoting healthier skin and preventing the progression of skin cancer.

Photodynamic Therapy is a clinically proven, non-invasive medical treatment primarily used to treat actinic keratoses (pre-cancerous skin lesions) and certain types of superficial skin cancers. Unlike "spot treatments" that only address visible lesions, PDT offers a comprehensive "field treatment." This means it identifies and destroys subclinical damage hidden beneath the surface of the skin before it can develop into larger, more dangerous growths.

What is Photodynamic Therapy?

PDT is a multi-step process that combines light energy with a specialized light-sensitive medication (a photosensitizer). At VIDA, our nurses apply a topical solution such as Levulan (5-aminolevulinic acid) or Metvix (methyl aminolevulinate) to the target area.

Once applied, the medication is left to "incubate" for 60–90 minutes, during which it is selectively absorbed by damaged or rapidly dividing cells. When these cells are subsequently exposed to a specific wavelength of light (Blue or Red light), a chemical reaction occurs that destroys the abnormal cells while leaving the surrounding healthy tissue intact.

Benefits of Photodynamic Therapy (PDT)

Choosing PDT at VIDA offers a proactive approach to long-term skin health:

  • Proactive Prevention: Treats "invisible" sun damage before it evolves into squamous cell carcinoma.
  • Superior Cosmetic Outcomes: Because it is non-surgical, PDT typically results in minimal scarring and improved skin texture.
  • High Success Rate: Extremely effective for clearing large areas of sun damage, such as the entire scalp, face, or forearms.
  • Surgical Alternative: Provides an effective option for patients who may not be candidates for surgery or who have multiple lesions.
  • Alberta Health Care Covered: PDT treatments at VIDA are 100% covered by Alberta Health Care, ensuring patients have access to essential cancer-prevention care.

What Conditions Can PDT Address?

Our dermatologists utilize PDT for a variety of clinical and aesthetic indications:

  • Actinic Keratosis (AK): Rough, scaly patches caused by years of sun exposure.
  • Superficial Basal Cell Carcinoma: Treating early-stage, non-melanoma skin cancers.
  • Bowen’s Disease: Also known as squamous cell carcinoma in situ.
  • Severe Acne: Targeting oil glands and bacteria to reduce inflammatory breakouts.
  • Photo-aging: Improving the overall quality and appearance of sun-damaged skin.

What To Expect During Your PDT Session

Your treatment is performed in our clinical facility under the supervision of dermatological experts:

  • Preparation & Incubation: After a thorough skin cleansing, the photosensitizer is applied. You will wait in our comfortable clinic for 60–90 minutes while the medication absorbs.
  • Light Activation: You will be placed under a specialized light device for approximately 10–20 minutes. You may feel a tingling, stinging, or burning sensation during this phase, which is well-managed by our team.
  • Post-Treatment Reaction: The treated area will likely become red and may peel or crust, similar to a sunburn, for 3–7 days. This is a sign that the damaged cells are being eliminated.
  • Crucial Protection: Your skin will be extremely light-sensitive for 48 hours after treatment. You must avoid direct sunlight and bright indoor lights, and we recommend bringing a wide-brimmed hat to your appointment.

When Will You See Results?

The skin typically goes through a "renewal" phase following PDT:

  • Initial Healing: Within 1–2 weeks, the damaged skin will peel off, revealing smoother, healthier tissue.
  • Long-Term Protection: By clearing the "field" of sun damage, PDT significantly reduces the number of new pre-cancerous lesions that would otherwise appear over the following months.
  • Frequency: Many patients achieve excellent clearance with just one session, though your dermatologist may recommend a follow-up session for more extensive damage
