Using a tiny microneedle, a very small amount of Botox is injected, very precisely, into several locations in the face. No sedation or local anesthetic is required and you can resume normal activities immediately. When injected in minute amounts, Botox works to paralyze those muscles that cause you to frown. Unlike collagen, there are no allergies associated with Botox. The injections take about 10 minutes, are inexpensive, and the effect lasts between four to six months.
Some patients experience a slight temporary bruising at the injection site.
This can be covered with makeup. In some cases, the Botox 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 any side effect depends on the muscles injected. Your doctor will discuss this with you in length before your treatment.
