It is best not to tattoo your pupils during pregnancy, because the anesthetic used in the process of tattooing pupils, the dyes used in tattooing eyeliner, and the adverse stimuli in the process of tattooing eyeliner can have a negative impact on the fetus and the pregnant woman. 1, anesthetic: when tattooing eyeliner, drugs such as lidocaine are usually used for local anesthesia or topical application to relieve the pain caused during the operation. However, the excessive use of lidocaine may lead to an increase in the blood concentration of anesthetics in the fetus, thus causing bradycardia or tachycardia, which may even endanger the life of the fetus; 2, chemical substances: the dyes used when tattooing eyeliner may contain a small amount of chemical ingredients, improper care may easily trigger swelling and inflammation of the tissue in the pupil area, affecting the health of pregnant women; 3, improper operation. The operation site is located around the eye, where the nerves and muscles are sensitive, so if improper operation stimulates pain in pregnant women during the operation, it may trigger contractions, leading to miscarriage or premature birth. Therefore, in daily life, pregnant women should avoid the use of drugs or skin care products containing more chemical ingredients and avoid irritating operations to avoid affecting the health of the fetus and pregnant women.
