The present invention relates to a photodynamic method of treating tattoos. The method comprises: (i) intradermally and/or locally delivering photosensitizer into tattooed target tissue; and (ii) irradiating the target tissue with activation energy at a wavelength appropriate to activate the photosensitizer. The present method causes the tattoo inks to fade or disappear completely. In preferred embodiments the tattoo will fade by at least 25%, more preferably at least 50%, even more preferably at least 75%.
