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
