Pregnant women are a special group of people and makeup is generally not recommended. This is because most of the cosmetics sold in the market, such as whitening creams, spot creams, foundations, mascaras, etc., contain chemical substances, which are not easily discharged from the body after being absorbed by the skin and are prone to adversely affect the development of the fetus. The disadvantages of makeup for pregnant women are as follows: 1. skin allergy: the hormone level in pregnant women’s body changes greatly after pregnancy, the skin protection barrier is more fragile and sensitive, and cosmetics contain hormones, vitamin A acid, fruit acids, keratin peeling ingredients and other substances, which can easily increase skin irritation and cause allergic reactions, which in turn will have a more serious impact on the development of the fetus; 2. The cosmetics in the market generally contain aromatic compounds, pigments, lead, mercury and other substances, and these substances are passed to the fetus through the blood and placenta after a pregnant woman wears makeup, affecting its growth and development and increasing the rate of fetal malformation. As mentioned above, it is advisable for women not to wear makeup during pregnancy. However, if you have to wear makeup, it is recommended that you choose cosmetics for pregnant women and remove them thoroughly afterwards to avoid the absorption of unfavorable substances into the bloodstream, which may affect the health of the mother and child.
