What the sources say
FDA says it has no information showing parabens as used in cosmetics affect health and continues to review studies. NIEHS calls parabens hormone-disrupting with uncertain effects and notes they can be absorbed through skin. A 2025 pregnancy skin care review lists parabens as avoidable, and AAD suggests using them sparingly. Limit: no need to panic over occasional use; where easy, choose paraben-free leave-on products.
