Botulinum toxin injections have been used both in the face and neck for many years. However, injection into the sternocleidomastoid muscle (SCM) has only been done to treat neck spasms. In this study botulinum toxin will be injected into the SCM to determine if this will result in a temporary slimming effect on the neck and produce a more feminine, youthful neck contour.
Description
The specific study objectives are to determine if:
* the neck circumference is decreased at 4 weeks after botulinum toxin (prabotulinumtoxinA-xvfs) injection.
* patients can appreciate a difference in their neck contour, self-confidence, and the way they perceive themselves post-injection via an aesthetics outcome and a neck perception survey.
* injection of the botulinum toxin into the sternocleidomastoid muscle is safe to perform based on adverse events.
