• Cerium oxide (CeO₂) nanopowders were successfully synthesized by a simple microwave-hydrothermal method. The UVB protection of an emulsion containing CeO₂ was evaluated in vitro and compared to the one provided by the same emulsion, zinc oxide (ZnO) instead of CeO₂. CeO₂ offered better protection against UVB radiation. Finally, in vitro cytotoxicity of CeO₂ and various ZnO commercial sunscreens was carried out using NCTC2544 cell line. Assessment of cell viability demonstrated that all tested ZnO commercial sunscreens reduce cell viability in a dose- and time-dependent manner whereas CeO₂ particles did not produce any effects on NCTC2544 growth at the highest concentration tested (80µg/ml).
