Botox is a non-invasive injection to help reduce the appearance of wrinkles. However, during the pregnancy most women choose not to use Botox even if their doctor says they can. Women most frequently cite worries over the baby's health as their reason to avoid Botox in pregnancy.
One survey of US physicians says that they found no real problems with using and found it "relatively" safe" in pregnancy. Recently the Cosmetic Physicians Society of Australia recommended that their physicians not use Botox in pregnancy. This is after a woman reported deafness and blindness in her baby after using a similar product during pregnancy.
