As soon as the photosensitizer is subjected to a light with a matching spectral array, it's converted from its ground state into an excited singlet state. This allows it to move energy to molecular oxygen, creating singlet oxygen and complimentary radicals that mediate cellular poisoning.
The Light
Throughout treatment, an unique light is radiated on the area where the photosensitizer was used. This light turns on the medication and destroys cancer cells or precancerous cells that it has actually targeted.

This causes a sequence of photochemical reactions that produces responsive oxygen species (ROS) that damages growth cells and kill cancer cells.

It can also be utilized to treat other sorts of skin cancer, consisting of superficial basic cell carcinoma. It can be utilized alone or with various other treatments, such as surgical procedure or radiation.
