Cosmetics for pregnant women generally do not cause heart disease in the fetus, but cosmetics for non-pregnant women may contain lead, mercury and other heavy metals, which may cause heart disease in the fetus. Women should be careful when choosing cosmetics after pregnancy, because cosmetics not intended for pregnant women may contain lead, mercury and other chemicals, these harmful substances may be absorbed by the fetus through the placenta, thus affecting the development of the fetus, which may cause the fetus to suffer from heart disease, and in serious cases, may even lead to fetal deformity, miscarriage and other accidents. Therefore, it is recommended not to use cosmetics during pregnancy, and if you need to use them, try to choose the type for pregnant women. If the fetus has heart disease, it is recommended to go to the hospital in time, under the guidance of the doctor to carry out standardized treatment to promote the alleviation of the condition.
