Applications
The topical Photodynamic Therapy (PDT) is based on the selective destruction of skin cancer cells in the epidermis and dermis. This is achieved by using a photosensitizer and light in the presence of oxygen. - Due to their higher metabolism, cancer cells absorb more of the photosensitizers or their constituents (such as ALA).
- When the skin is radiated with the high-energy light in the red part of the spectrum, singlet oxygen is generated, which fatally damages the skin cancer cells.
- Clinical data show a complete healing of 70 – 78 % of the patients after a single treatment and 90 % after a second treatment a week later.
- Because PDT has cosmetically better results, it is increasingly replacing cryosurgery.
Additionally, red light is increasingly being used to support wound-healing processes.
