Can parabens from lotions and cosmetics alter DNA methylation?
Parabens are preservatives used in some lotions and cosmetics. A pregnancy study linked paraben exposure with DNA methylation changes in cord blood, so simpler baby care is a wise choice.
What we know
Parabens are preservatives used in some lotions, cosmetics, shampoos, and other personal care products. They help stop germs from growing in a product, but they can also be absorbed through skin.
A 2014 exposure study found that personal care product use was linked with urinary paraben levels among women at a fertility clinic. A 2026 Environment International study found that maternal paraben exposure in early pregnancy was associated with changes in cord blood DNA methylation.
What this means for your family
DNA methylation is one way the body helps turn genes on or off. The study does not prove that parabens cause disease. It does show that pregnancy exposure may be linked with measurable changes in a baby's cord blood.
Because babies and pregnant parents use personal care products every day, simple swaps can make sense.
Simple safer steps
Choose baby soap and lotion labeled paraben-free. Use fewer leave-on products when you can. Check ingredient lists for methylparaben, propylparaben, butylparaben, and ethylparaben.
You do not need a perfect bathroom shelf. Start with the products used most often on skin.
