There are a few key areas to avoid when injecting Botox. These include the forehead, the area between the eyebrows, and the crow's feet. These are some of the areas that are injected most often, and injecting Botox into them can cause a frozen or surprised expression. A qualified and experienced injector should never inject the area near the orbital bone just above the pupil.
If you inject Botox here, it may descend into the upper eyelid and cause a drooping of the eyelid. This can last from weeks to months. Not everyone is a good candidate for Botox. If you have poor general health, your skin is very thick, or you have muscle weakness at the proposed injection site, you may not be a good candidate for Botox.
Usually, doctors recommend not using Botox during pregnancy or breastfeeding. And Botox should not be used in people who are allergic to cow's milk protein.
