Photodynamic Therapy (PDT)/Metvix
Photodynamic therapy (PDT) is a treatment used mainly for superficial types of skin cancer. PDT is effective in treating actinic keratoses and superficial basal cell carcinomas. PDT is also sometimes used off-label for facial rejuvenation and to treat mild to moderate acne.
GET THE FACTS
Photodynamic therapy (PDT) is a two-stage treatment that combines photosensitizing agents, oxygen and light, to create a photochemical reaction that selectively destroys cancer cells and/or acne causing bacteria. Photosensitizing agents are medications that are applied topically to affected areas. They concentrate in cancer cells and only become active when light of a certain wavelength (red light) is directed onto the area where the cancer is. The photodynamic reaction between the photosensitizing agent, light and oxygen kills the cancer cells.
BENEFITS
• Treats larger area of precancerous lesions all at the same time.
• Does not leave scarring
• Affects only targeted cells, helping to maintain skin integrity.
• Destroys acne-causing bacteria on the skin.
