A major scientific study found that using sunscreen "massively increases" your risk of skin cancers, including melanoma.
Spread on: Social media posts, late June 2026
The real story
The study behind the posts looked at the 'sunscreen paradox', where people stay out in strong sun longer because they feel protected, or forget to reapply. It did not find that sunscreen itself causes cancer. In fact, it stressed using enough sunscreen, reapplying often and limiting UV exposure. The posts turned the finding upside down.
The fact-checker's verdict: “False”. Our label never goes further than theirs.
When a post cites 'the biggest study ever', find the study's own conclusion; misread research is one of the most common health tricks online.
