Metvix photodynamic therapy, also called Metvix PDT, is a non-invasive method of removing precancerous and cancerous cell carcinomas (often actinic keratoses and basal cell carcinoma) from the skin. While cancerous cells can be removed by surgical methods, these commonly cause scarring.
For this reason, Metvix photodynamic therapy is a popular alternative for removing cancerous and precancerous cells from the face, as it does not cause scarring.
The treatment involves the activation of Metvix, a special cream, with a red light. The Metvix cream is applied to, and absorbed by, the cancerous cells on the skin. The red light then creates a reaction in the cream that kills the cancerous cells.
