Titanium dioxide sunscreen
Sunscreen. Blocks ultraviolet radiation. Acts on the skin surface. No direct brain effect — does not cross the blood–brain barrier.
Benefits
A mineral (physical) UV filter that reflects and scatters UVB and some UVA; gentle for sensitive skin and comparatively reef-safer.
Risks
Can leave a white cast and feel heavy and gives weaker long-UVA coverage than some filters. Avoid inhaling loose-powder or spray forms.
