Abstract
A method for forming a photosensitizer product that is resistant to absorption by living tissue that may include binding a photosensitizer compound with an oxide-containing particle to provide the photosensitizer derivative having a microscale size, and mixing the photosensitizer derivative into a lotion. The microscale size of the photosensitizer derivative obstructs absorption by cell tissue.
