Titanium dioxide and zinc oxide are considered safe and effective as sunscreen ingredients. These minerals work by providing a physical barrier that reflect or scatter UV radiation. They are less likely to cause skin irritation and allergies, thus recommended for sensitive skin. However, some concerns were raised about their nano forms, which could potentially penetrate skin. Overall, the evidence suggests that they remain on the surface of the skin and do not enter the body, ensuring their safety. For cosmetics involving inhalation exposure, such as powders, the safety of nanoparticle use is still under scrutiny.
