Abstract
A system and method are provided for preventing damage to the epidermis or other epithelial or non-target tissue during photodynamic therapy treatment. For example, an inhibiting radiation can be used to control formation of a photosensitizer from a precursor photosensitizer in the epidermis or epithelial tissue. Subsequent application of a treatment radiation can activate the photosensitizer to damage or destroy target sites while the non-target tissue remains substantially unaffected.
