Are acrylic nails safe during pregnancy?

What does the evidence say about acrylic nails during pregnancy?

1. Adding a strong exhaust system at the nail table cut fume exposure by more than 90 percent in one study, from an average of 8.7 ppm down to 0.6 ppm across a work shift, and methyl methacrylate wasn't detected at all once that ventilation was running. 1
2. Real air testing inside a dozen New York City nail salons found chemical levels that were mostly low or too faint to detect, even though three out of four of those salons still fell short of the minimum fresh-air ventilation rules meant to protect everyone in the room. 2
3. Methyl methacrylate (MMA) has been banned from nail products for years, yet air sampling has still turned it up inside some salons, which is a good reason to ask your technician whether they use an MMA-free acrylic powder and liquid. 3
4. The higher miscarriage risk found in cosmetologist research tracked with working long, full-time hours around chemical services every day, not with getting an occasional personal manicure, and workers who only did light chemical work saw no increased risk at all. 4
5. Nail technicians are mostly women of childbearing age doing this work every single day, which is exactly why occupational health researchers push salons toward better ventilation and safer practices, the same habits that make an occasional visit even lower-risk for a customer. 5

Is acrylic nails safe in each trimester?

• First trimester. Morning sickness can make salon smells feel stronger and harder to tolerate right now. If the odor bothers you, ask for a seat near a fan or open door, and know that some people simply choose to wait until after this trimester as an extra-cautious step while major organs are forming.
• Second trimester. This is usually the easiest trimester for a longer appointment, since nausea has often eased and sitting still feels more comfortable. Good habits to keep up: pick a salon with visible ventilation, and ask whether the acrylic system they use is MMA-free.
• Third trimester. Holding one hand position for a full set or fill gets harder as your belly grows, so don't hesitate to ask for a stretch break partway through. The exposure guidance doesn't change this late in pregnancy: fresh airflow in the room still matters more than the brand of product used.
