NCT ID NCT06068855
First seen Jan 07, 2026 · Last updated May 12, 2026 · Updated 22 times
Summary
This study tested whether BOTOX injections can make the jawline look slimmer by relaxing the chewing muscles. About 249 adults with a wide, square lower face received either BOTOX or a placebo. The main goal was to see if the treatment reduced jaw muscle prominence by at least two grades on a 5-point scale, as judged by both doctors and participants.
