Pivotal Trial

Summary

This trial is testing BOTOX injections to see if they can temporarily improve the appearance of prominent neck muscles. The study will include about 400 participants who will receive BOTOX. BOTOX works by temporarily stopping muscles from moving, which can make the skin look smoother. BOTOX has been used for over a decade to improve the appearance of facial lines.
