However, it is worth noting that there has been some debate surrounding the safety of titanium dioxide nanoparticles. Nanoparticles are particles that are smaller than 100 nanometers in size, and they have unique properties compared to larger particles. Some studies have suggested that these nanoparticles may have the potential to penetrate the skin and enter the bloodstream, raising concerns about their long-term effects on human health.
To address these concerns, regulatory authorities have set limits on the size and concentration of titanium dioxide nanoparticles in cosmetic products. The FDA, for example, requires that nanoparticles used in sunscreens have a size of 100 nanometers or larger. This helps to ensure that the particles remain on the surface of the skin and do not penetrate into deeper layers.
In conclusion, titanium dioxide is a valuable ingredient in sunscreen and skincare products due to its ability to provide broad-spectrum protection and improve the appearance of the skin. It is considered safe for topical use, although there are regulations in place to limit the use of nanoparticles. As always, it is important to follow the instructions provided by manufacturers and consult with a healthcare professional if you have any concerns about the use of titanium dioxide in products.
