It is possible to get Botox injections in the first trimester of pregnancy, but it's not recommended. Botox is a neurotoxin that works by temporarily paralyzing specific muscles or blocking nerve signals in the body. Although there are no known adverse effects of obtaining Botox while pregnant, experts advise against receiving it during this time because it can affect your baby's development. Additionally, if you already have pre-existing conditions that require frequent Botox injections, you may want to reconsider continuing them during pregnancy.
