Can a gel injection sharpen the jawline? a trial puts it to the test
NCT ID NCT07805512
First seen Sep 04, 2026 · Last updated Sep 04, 2026
Summary
Researchers are testing whether Restylane Shaype, an injectable gel made of hyaluronic acid, can improve jawline definition in Chinese adults. The study includes about 162 participants aged 18 and older who want treatment on both sides of their jaw. Two-thirds receive the gel, while the rest get no treatment. Blinded evaluators will rate jawline improvement using a standard scale to see if the gel makes a visible difference.
