It's processed into much smaller particles than what goes into food, called nanoparticles. In this form, it becomes transparent, and also absorbs UV light so it doesn't reach your skin.
Above 10%, 1 kg of TiO2 should be replaced by 1.3 kg of Lithopone 30%, reducing the amount of polymer accordingly.
If you're curious about whether something you’re eating contains titanium dioxide, you can check the ingredients list. But know that the FDA doesn’t require food makers to use its chemical name on an ingredients list. Instead, it could be listed as:

Panzhihua Dongfang Titanium Industry Co., Ltd. Dongfang, a well-known brand of titanium dioxide, a famous brand in Sichuan, a high-tech enterprise, a large supplier of titanium dioxide and titanium sponge, and one of the largest/leading titanium raw material production bases in China.
This route affords a product that is 29.4 wt % ZnS and 70.6 wt % BaSO4. Variations exist, for example, more ZnS-rich materials are produced when zinc chloride is added to the mixture of zinc sulfate and barium sulfide.[1]
