It is best not to do eyebrows during breastfeeding for the following reasons: 1, the body’s resistance to disease is relatively weak during breastfeeding, and doing eyebrows is a traumatic operation that can easily lead to pathogenic microbial invasion and infection. 2, the process of doing eyebrows will use local anesthetic drugs, which may be absorbed into the bloodstream and excreted through breast milk, which is not conducive to breastfeeding. 3, the process of doing eyebrows has some chemical pigments, and if the quality of these chemical pigments is faulty, they will affect the quality of breast milk. The quality of these chemical pigments is questionable and will affect the quality of breast milk after being absorbed into the blood circulation, thus affecting the health of the baby. It is recommended that breastfeeding mothers should not do eyebrows, including lip bleaching and other cosmetic operations.
