When you put sunscreen on your skin, a chemical called oxybenzone can get into your bloodstream, and some lab and small human studies suggest it might mess with your hormones, affect baby weight depending on whether it's a boy or girl, and harm brain cells in test tubes.
Evidence Quality Assessment
Claim Status
appropriately stated
Study Design Support
Design supports claim
Appropriate Language Strength
association
Can only show association/correlation
Assessment Explanation
The claim correctly uses 'associated' to reflect correlational findings from in vitro and limited human studies, avoiding definitive causal language. It accurately distinguishes between human observations (limited) and cell line data (in vitro). The inclusion of multiple endpoints (anti-androgenic effects, birth weight changes, neurotoxicity) is appropriately qualified by the scope of evidence. No overstatement occurs because the claim does not claim causation, mechanism, or population-wide effects.

Sunscreen Safety and Efficacy for the Prevention of Cutaneous Neoplasm
The study says oxybenzone in sunscreen can mess with your hormones and nervous system, so you should avoid it — which matches what the claim says.
