No results posted yet for this study

Summary

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.
