How does TiO2 work in sunscreen?
When used in sunscreen, Titanium Dioxide is typically ground into small particles. This increases its ability to protect against UVB rays. This small particle size also makes it less noticeable on skin, making it ideal for those with darker skin tones.

Are titanium fumes safe?
Low-grade fever after inhalation exposure is not explicable by hydrogen chloride inhalation and therefore appeared to be caused by titanium dioxide inhalation, manifesting as metal fume fever. Titanium dioxide is thought to have no remarkable human toxicity and is considered to be safe clinically.
Can titanium dioxide be absorbed through skin?
TiO2NPs present in cosmetics have the potential to penetrate through the stratum corneum into viable skin layers via intercellular channels, hair follicles, and sweat glands [8].
