Details.
Uses structural hyaluronic acid filler placed at the gonial angle and along the mandibular border to define the jawline, sharpen the jaw-to-neck line, and create a stronger lower-face outline. Two millilitres is described as a common starting package, and most full jawlines require two to four syringes depending on starting anatomy and desired definition. Results typically last 12 to 18 months. Expect swelling for three to seven days, possible bruising, and mild tenderness with chewing. Assess the settled result at two weeks.
