A report I saw this AM on Yahoo ( I think) said that some now believe there is a connection between sunscreen and alzheimers.
University of Ulster researchers are specifically STUDYING nanoparticles present in chemicals found in sunscreens (& an additive in some diesel fuels (titanium dioxide and cerium oxide); and their connection to neurodegenerative diseases, such as Alzheimer’s and Parkinson’s diseases.
Let's not panic , quite yet.
