Is it safe to use propylparaben-containing skincare while pregnant?
No. Propylparaben exposure in pregnancy affects ovarian reserve across generations.
What's actually in it
Propylparaben is used as a preservative in lotions, face creams, sunscreens, and cosmetics. The mother's skin absorbs it. From there, it reaches the developing fetus. For a female fetus, the ovarian reserve is being laid down during pregnancy, and chemical disruption during this window has transgenerational effects.
Parabens were thought to be safer in small amounts. Transgenerational data is shifting that view.
What the research says
A 2025 study in Nat Commun documented transgenerational inheritance of diminished ovarian reserve triggered by prenatal propylparaben exposure in mice. The effect reached grandchildren, suggesting epigenetic transmission across generations. Human exposure levels align with what's achievable through daily skincare use.
For pregnancy, switch to paraben-free products across the skincare routine. Labels list the preservatives directly ("propylparaben," "methylparaben," "butylparaben"). Brands like Attitude, Beautycounter, 100% Pure, Shea Moisture offer paraben-free options. Simpler products with fewer ingredients also make it easier. For moisturizing, pure shea butter, coconut oil, or single-ingredient carrier oils skip the preservative problem entirely.
