Influence of titanium dioxide nanoparticles on skin surface temperature at sunlight irradiation.

In this paper, we report about simulated distribution of density of absorbed light energy within human skin following light illumination with a combination of three wavelengths (310, 514 and 800 nm) with ratios similar to ultraviolet, visible and infrared fractions of the solar irradiance spectrum. We study heat distribution within the skin treated with a sunscreen containing TiO(2) nanoparticles. Our results show that administration of TiO(2) particles does not cause heat load on the tissue.
