A general procedure does not use anesthesia, although sometimes an anesthetic cream will be applied to the area to be treated.
Botox procedures typically last for about thirty minutes, with results lasting anywhere from about three to six months.

What is a BOTOX® procedure?
BOTOX® procedures are a therapeutic muscle-relaxing agent that works at motor nerve endings (nerves that lead to muscles). BOTOX®® Cosmetic is a drug used for the temporary improvement in the appearance of moderate to severe glabellar lines (frown lines). These frown lines come from muscles called corrugator and/or procerus muscles. The BOTOX® procedure is the name used for the process of injecting the BOTOX® Cosmetic product into the patient.
BOTOX® procedures were approved by the U.S. Food and Drug Administration (FDA) for cosmetic use in April 2002. (It has been approved for the procedure of several medical conditions since 1989.) BOTOX® is a trade name for botulinum toxin A. BOTOX® is related to botulism.
BOTOX® procedures are successfully used to treat blepharospasm and strabismus, and BOTOX® procedures are also proven useful in treating cervical dystonia -- these are all conditions that in some way involve spasms, involuntary muscle contractions. Within a few hours to a couple of days after the botulinum toxin is injected into the affected muscle(s), the spasms or contractions are reduced or eliminated altogether. The effects of BOTOX® procedures are not permanent, reportedly lasting anywhere from three to eight months. By injecting the toxin directly into a certain muscle or muscle group, the risk of the BOTOX® procedures spreading to other areas of the body is greatly diminished.
When BOTOX® -- botulinum toxin A -- is injected into the muscles surrounding the eyes, for instance, those muscles can not "scrunch up" for a period of time. They are paralyzed. So the wrinkles in that area, often referred to as "crow's-feet," temporarily go away.
