Is it safe for pregnant women to use personal care products containing parabens?

What's actually in it

Parabens are a class of chemicals used as preservatives in many personal care products. They are designed to stop mold and bacteria from growing in your lotions, shampoos, and cosmetics. Because these products are applied directly to your skin, the chemicals can enter your body and circulate through your system.

While these ingredients are common, they are not just sitting on your skin. They are part of a complex mix of chemicals that scientists are now linking to long-term health changes in women. When you use these products, you are often exposed to a mixture of substances, including phthalates (chemicals that make plastic soft) and phenols, which can interact with your body's natural systems.

What the research says

A 2026 study in Environ Res found that repeated exposure to parabens, along with phthalates and phenols, is associated with metabolic syndrome in women. This means these chemicals may disrupt how your body processes energy and regulates health.

The impact of personal care products on pregnancy is also a major focus of current science. A 2026 study in Environ Int created a map of evidence regarding how these products affect fetal growth. This peer-reviewed research highlights that the chemicals found in everyday items are not neutral and require closer attention during pregnancy.

Other research shows that these products can affect your internal chemistry. A 2026 study in Ecotoxicol Environ Saf identified a link between personal care product use and changes in thyroid function. A separate 2026 study in Environ Sci Technol confirmed that these exposures can increase the risk of high cholesterol, with thyroid hormones acting as a key link in that process.
