The integrity of surface skin cells was evaluated with and without solar simulated irradiation. The integrity of the stratum corneum was significantly lower in individuals treated with P25TiO₂NPs under the light in comparison to the ones that received the functionalized nanoparticles. Cell membrane suffering is evident (Fig. 9), and it is in accordance with the ROS levels and macromolecule oxidation found in vitro for the irradiated P25TiO₂NPs. Disruption of the superficial skin layer was observed in all animals treated with no functionalized nanoparticles, under irradiation. This data expands the findings by the group of Professors Fubini and Fenoglio, who showed that P25TiO₂NPs could impact the lipid structure at the top few microns of the stratum corneum [55]. Control skin under irradiation and without any topic formulation did not show changes in cell structure.

How can I tell if a product has titanium dioxide in it? How can I avoid the ingredient?

With 30% of the world's lithopone factories located in China, the country has become a major player in the global lithopone market. Chinese manufacturers are able to produce lithopone at a competitive price, making it an attractive option for companies looking to reduce their production costs. In addition, China's large production capacity ensures a steady and reliable supply of lithopone to markets around the world.
