Pregnant women can wear make-up, and they can wear light make-up occasionally, but they cannot wear heavy make-up for a long time. If a pregnant woman participates in some public occasions, she can occasionally wear some light makeup, and she should choose plant-based cosmetics so as not to affect her own health and the growth and development of the fetus. However, they should not wear heavy makeup for a long time because cosmetics contain chemical substances and heavy metal ions, which are toxic and harmful ingredients that are not only detrimental to a pregnant woman’s health, but also easy to affect the growth and development of the fetus, or even lead to fetal deformities. In addition, during pregnancy, pregnant women should stay away from toxic and radioactive environments, quit smoking, drinking and other bad habits, and go to the hospital regularly for checkups to see how the fetus is growing and developing.
