V-Line Jaw Contouring in Gangnam, Seoul
Muscle-relaxing injections soften a wide or square jaw angle over several weeks, gradually revealing the narrower, more tapered "V-line" silhouette — no incisions, no bone surgery.
Softening the Jaw Angle, No Surgery Required
A wide or square jawline is often caused less by bone structure than by an overdeveloped masseter muscle — the muscle you use to chew. This treatment injects a muscle relaxant directly into the masseter, causing it to gradually shrink over several weeks as it's used less intensely.
As the muscle relaxes and reduces in size, the lower face narrows and the jaw angle softens, creating the tapered "V-line" contour prized in Korean aesthetics — without touching bone or requiring any incision.
Because it targets muscle bulk rather than bone or fat, results build gradually over 4–8 weeks and are temporary, making this a low-commitment way to test a narrower jawline before considering more permanent options like a full facial slimming program.
- No incisions, no bone surgery
- Softer, more tapered jaw angle
- Also eases teeth-grinding tension
- Temporary — a low-risk way to test the look
Candidates & Safety Information

- Frequent teeth-grinding or jaw clenching
- Want a reversible, non-surgical narrowing option
May Not Be Ideal For

Common Side Effects
- Mild soreness or bruising at injection sites

- Gradual, not immediate, visible change
Your Session & Recovery Timeline
Your doctor evaluates jaw width, muscle bulk, and bite pattern to confirm masseter injections are the right approach for your goals.
A series of small injections is placed into the masseter muscle on both sides; topical numbing is optional as discomfort is typically minimal.
Mild soreness or light bruising at injection points is normal; most patients return to normal activities the same day.
The muscle begins to visibly relax and reduce in bulk; chewing feels normal but slightly less forceful with tough foods.
Full contouring effect is visible; results typically last 4–6 months before the muscle gradually regains its original size.

V-Line Jaw Contouring — FAQ
When will I see results?
Results build gradually as the muscle relaxes, with most patients seeing a visible change by week 2–4 and the full contouring effect by week 6–8. This is not an immediate, same-day result.
Will this weaken my ability to chew?
You'll retain normal chewing ability for everyday foods; the change is a reduction in excess muscle bulk and forceful clenching strength, not a loss of basic jaw function.
Is this the same as filler-based jaw contouring?
No — this treatment relaxes and shrinks the masseter muscle to narrow a wide jaw. If you're looking to add structure or projection elsewhere in the face, see Chin Contouring & Projection or Cheek & Mid-Face Contouring.
How long do results last?
Most patients see results last 4–6 months before the muscle gradually rebuilds and repeat treatment is needed to maintain the narrower contour.
Can I combine this with other contouring treatments?
Yes — many patients pair this with cheek, chin, or fat-dissolving treatments as part of our Full Facial Slimming Program for a more complete, coordinated result.
