Description
The application is very simple and consists of two phases:
- In the first phase, the dermatologist prepares the skin lesion when necessary and then applies a cream containing a photosensitive active ingredient. The area is then covered to facilitate the penetration of the product and to shield the skin from light while the photosensitizer is left to incubate for 1 to 3 hours, depending on the lesion being treated.
- In the second phase, after the incubation period, the area to be treated is cleaned and then illuminated with a red light lamp for 10 minutes.
Photodynamic therapy is mainly used for the treatment of superficial non-melanoma skin cancer, but has many other uses in dermatology, mainly in skin rejuvenation, acne and other inflammatory and infectious diseases.
