Using a tiny micro-needle, a very small amount of Botox is injected, very precisely, into several locations on the face. Because the needle is so fine and only a small amount of liquid is used, the pain associated with the injections is minimal. Most patients compare the sensation to a bug bite. No sedation or local anesthetic is required, and you can resume normal activities immediately. You can even drive yourself home or back to the office.
Some patients experience a slight temporary bruising at the injection site.
This can be covered with make-up. Temporary bruising is the most common side effect. In some cases, the toxin can migrate and cause a temporary weakness of nearby muscles. In rare cases, there can be a drooping of an eyelid or asymmetry of facial expression. The risk of side effect depends on the muscles injected.
