We report about alteration of optical properties of the superficial layer of human skin at two UV range wavelengths (310 and 400 nm) by application of 35–200 nm –sized particles of titanium dioxide (TiO2), silicon (Si) and zinc oxide (ZnO). The study, based on combination of the Mie theory and Monte Carlo simulations, reveals the optimal sizes of the nanoparticles minimizing the transmittance of the layer for the considered wavelengths.
