Nail art is generally not recommended when you are pregnant. Many nail polishes contain many toxic substances, such as ethyl acetate, tincture of benzene dicarboxylic acid and other chemicals, which can be soaked deep into the skin through the nails and transported to the fetus, resulting in fetal dysplasia or fetal malformations possibly. They can also be inhaled through the mouth and nose, resulting in physical injury to both the pregnant woman and the fetus. Therefore, nail art is actually not recommended during pregnancy. If pregnant mothers must use nail art, then they must choose high-quality nail polish, choose nail polish that can be used by pregnant women, but they also need to be washed as soon as possible to avoid exposure to toxic and harmful substances, and also pay attention to ventilation conditions to reduce inhalation. In short, pregnant try to avoid the use of nail polish, non-compulsory use must also be very careful to reduce exposure to nail polish.
