Occasional make-up during pregnancy has little effect on the fetus, but frequent make-up or the use of substandard cosmetics may have some effect on the fetus. Some cosmetics contain hormone ingredients and heavy metals, which may be absorbed through the skin after frequent make-up application, and may enter the fetus through the placental barrier, which may cause abnormal development of the fetus’ nervous system. If you want to wear makeup during pregnancy, you can wear makeup occasionally or choose safer cosmetics suitable for pregnant women to apply. The choice of cosmetics during pregnancy should be careful, even if you use maternity cosmetics during pregnancy, you should try to wear light makeup, and remember to wash it off after applying makeup to avoid hyperpigmentation. During pregnancy, you should do a good job of regular maternity checkups, and if you feel unwell during pregnancy, it is recommended that you go to the hospital in a timely manner in order to avoid adverse consequences.
