Photodynamic Treatment (PDT)

Photodynamic therapy (PDT) is a treatment for sun damage of the skin or actinic/solar keratosis – which are pre-cancerous lesions of the skin. These rough areas are caused by damage from sunlight and mean that you are more likely to get skin cancer in the future unless they are treated. It is a selective treatment. It only affects the damaged cells and after exposure to a special white light destroys the cancers cells. A photosensitizing lotion is applied on the skin, at the surgery, which is followed by exposure to a special light source after an hour, which activates the medication. That in turn is selectively targeting the sun damaged cells only and destroys them. The skin of the area treated develops an inflammatory reaction that eases after 2 weeks. It dries up, flakes off and allow the healthy normal skin to regenerate. PDT is relatively safe and effective and produces excellent cosmetic results with few adverse effects. It has the advantage of allowing application to large areas. PDT reduces the number of pre-cancerous lesions and early cancerous lesions by 81-91%. It also improves the skin complexion. Occasionally 1-3 treatments are needed to achieve adequate results.

Frequently asked questions

  • How will I know if I need PDT?
    • The Doctor or Nurse at Skin Scan Clinic will determine if this is the most appropriate treatment for your condition. It is best suited for patients with widespread precancerous skin lesions or where shorter downtimes related to treatment effects is preferred. Some would use it to treat extensive sun damage only. You will then need to have a consultation with a Nurse before going ahead with the PDT treatment. The Nurse or PDT Therapist will discuss the treatment, procedure, consent, aftercare instructions and take photographs. Your treatment will not take place on the same day as your consultation.
