ABSTRACT:
A method and apparatus for selectively photobleaching or killing pigmented tissues by photochemically converting pigments in the tissues using light and specifically two-photon excitation. Phototoxic products thereby produced then kill pigmented cells. Hyperthermia or an exogenous agent can also be added to augment efficacy. The present invention is also directed to selective thermal destruction of pigmented tissues using related optical means.
