With every cosmetic procedure, there are a few cons. With Botox, it is a pretty safe cosmetic procedure. The few side effects that can occur with Botox that everyone interested in getting Botox injections should be aware of include: • Bruising at the site of the injection(s) • Slight pain at the injection site • Flu-like symptoms • Headache • Redness • Nausea • Temporary facial weakness • Temporary drooping • When using Botox, you may see specific signs and symptoms that are very rare but should be noted including breathing problems, trouble swallowing, slurred speech, and muscle weakness. These certain individuals who shouldn’t get Botox injections are women who are pregnant or breastfeeding, anyone who is allergic to cow’s milk protein, or those who have a neurological disease.
