Definition or slimming? Read jawline filler vs. masseter Botox — they do opposite things.
Hyaluronic acid filler placed along the jaw, injected personally by Dr. Amir Mortazavi, MD.
A defined jawline depends on a continuous, sharp border between face and neck. With age, that border softens — bone resorbs at the jaw angle, soft tissue descends over it, and the line that used to be crisp becomes indistinct.
Filler placed along the jaw body and at the angle restores that edge, sharpening the transition and improving definition in profile.
Definition and slimming are opposite goals. Make sure you know which you want.
Jawline filler makes the jaw sharper and more defined. It adds structure along the border.
Masseter Botox makes the lower face narrower. It reduces muscle bulk.
If your complaint is that your jaw looks wide or square, filler is the wrong treatment — it will emphasise width, not reduce it. If your complaint is that your jawline has lost its edge, filler is right.
Some patients need both: masseter to reduce width, filler to define the border. That's assessed rather than assumed.
Filler doesn't fix everything that makes a jawline look undefined.
Four different problems produce the same complaint, and only one of them is a filler problem:
Loss of bone and structural support at the jaw → filler. This treatment.
Submental fullness — softness under the chin → Kybella or surgery. Adding filler above a full submental area emphasises it.
The platysma pulling the jawline down → neurotoxin to the neck bands. Filler works against that pull rather than releasing it.
Genuine skin laxity and jowling → surgical. No injectable removes excess tissue, and filling a jawline with significant laxity adds weight to tissue that's already descending.
Most patients have more than one component. Dr. Mortazavi will tell you which parts filler addresses and which it won't — including when the honest answer is that you need a surgeon.
Chin projection is usually part of this.
The jawline reads as a single line from chin to ear. Treating the jaw while leaving a recessed chin untreated frequently produces an imbalanced result — the sides look defined and the front doesn't follow. Chin filler is often assessed alongside, and facial balancing treats the lower face as one plan when several areas are involved.
What to expect: 30 to 40 minutes with numbing. Results visible immediately, though swelling means the true result is at two weeks. Bruising is common along the jaw. Duration typically 12 to 18 months — longer than most areas, since jawline filler is placed deep on bone where it's more stable.
This area is treated with more product than most, since structural support requires volume. That's a reason to be particular about who places it — deep placement on bone by someone who can assess the whole lower face produces a different result than filling a border.
