Is propylparaben in skincare a pregnancy concern?
Use caution. A 2025 mouse study found prenatal propylparaben exposure affected ovarian reserve across generations, so pregnancy is a smart time to simplify skincare.
What's actually in it
Propylparaben is a preservative used in some lotions, creams, sunscreens, cosmetics, and personal-care products. It helps prevent microbial growth, but it is also studied as an endocrine-disrupting chemical.
During pregnancy, the goal is not panic. The goal is to lower repeat exposure when the swap is easy. Start with products that stay on skin for hours, like lotion, face cream, and body cream.
What the research says
A 2025 study in Nature Communications found that prenatal propylparaben exposure in mice was linked with diminished ovarian reserve in F1 to F3 offspring. The study reported more follicular atresia, lower anti-Müllerian hormone, and epigenetic changes tied to the Rhobtb1 pathway.
This is mouse research, not proof that one lotion causes infertility in people. It is still a strong reason to read labels during pregnancy. Look for propylparaben, methylparaben, butylparaben, and ethylparaben. Choose simpler soaps, shampoo bars, and moisturizers with clear ingredient lists. For leave-on products, avoid propylparaben when a good alternative is easy to find.
