Photodynamic Therapy (PDT Treatment) is the one of the most recent advances in acne therapy and the treatment of pre-cancerous skin lesions.
The procedure involves the application of a photosensitising agent, which is then activated with a blue light. The medicated cream inactivates the bacteria that trigger acne, exfoliates the skin to unclog pores, and shrinks the sebaceous glands in the skin.
It also effectively destroys pre-cancerous cells. The medicated PDT treatment program has significant and long lasting effects. For severe acne, you may require 3-6 treatments administered 2-4 months apart.
Patients must wear sunscreen and protect skin from sunlight and other strong lighting.
