Hormone Disruption

Oxybenzone, found in some sunscreens, is suspected of disrupting hormone function based on in vitro and animal studies. Human studies are limited and show mixed results, making definitive conclusions difficult.

Oxybenzone, a common ingredient in sunscreens, is suspected to disrupt hormone function by interfering with estrogen and androgen pathways. This interference can potentially lead to various endocrine-related issues. Evidence for this disruption primarily comes from in vitro (laboratory) and animal studies, where significant hormonal effects have been observed. However, human studies investigating the link between oxybenzone exposure and hormone disruption are limited and yield inconsistent results, making it difficult to definitively confirm the effect in humans. Potential effects are varied and depend on the individual and exposure level.
