Photodynamic therapy also known as PDT involves the application of a cream that sensitizes the skin cancer tumour cells that are subsequently destroyed during the light or laser illumination phase of treatment. PDT can be used to treat superficial skin cancers, sun-damaged skin to target early or pre-cancerous changes (actinic keratoses) and acne. Cosmetic outcomes after PDT are generally better than other skin cancer treatments due to its selective targeting of skin cancer cells.
Photodynamic therapy (PDT) utilizing natural daylight is a new well tolerated way to utilize this useful technique for the treatment of pre-cancerous skin changes (actinic keratoses). Combining photodynamic therapy with laser can also enhance both medical and cosmetic laser outcomes.
