As soon as the photosensitizer is revealed to a light with a matching spectral array, it's transformed from its ground state into a fired up singlet state. This allows it to transfer energy to molecular oxygen, creating singlet oxygen and complimentary radicals that mediate mobile poisoning.
The Light
During therapy, an unique light is shined on the location where the photosensitizer was used. This light activates the medicine and ruins cancer cells or precancerous cells that it has targeted.

This triggers a series of photochemical reactions that produces responsive oxygen species (ROS) that damages tumor tissue and eliminate cancer cells.
PDT is most often made use of to treat actinic keratoses and in situ squamous cell cancer (Bowen disease).
