Overview
What are jawline contouring injections?
Jawline contouring injections, known in Korea as square-jaw botox (사각턱 보톡스), place botulinum toxin into the masseter muscle on each side of the lower face. The masseter is the main chewing muscle; in people who clench, grind or simply have strong muscles, it bulks outward and gives the face a square, heavy outline. Relaxing part of its activity lets the muscle gradually slim over several weeks, so the jaw angle softens and the face reads as more oval. Bone is not changed, which is why the result is natural and reversible.
At Oaro the product is Nabota, a Korean botulinum toxin type A that is also approved in the United States and Europe. Jawline injections are one of the most requested treatments for visitors to Seoul because the effect is reliable, the visit is short and there is no downtime. Patients who grind their teeth often notice less jaw tension and fewer tension headaches as a side benefit.
How jawline contouring injections work at Oaro
At Oaro Dermatology Clinic in Apgujeong, Seoul, Dr. Chang-hyun Kim and Dr. Ji-ho Park, both board-certified dermatologists, assess the masseter by asking you to clench while they palpate its thickness and borders. The dose, usually 25–50 units per side, is placed in the lower, bulkier part of the muscle to avoid affecting the smile. Where the square look is partly bone or fat rather than muscle, we may suggest jawline fillers to refine the angle, double chin injections for submental fullness, or lifting energy from our laser and lifting hub for laxity. Compare options on the jawline slimming page and the injectable treatments hub. Written aftercare and a care notebook entry follow every visit.

Treatment goals
Common goals for jawline contouring injections
A slimmer lower face
Softening a square or wide jaw angle so the face looks more oval, without surgery.
Relief from clenching and grinding
Reduced masseter activity may ease jaw tension, bruxism and related headaches.

Different doses on each side may even out a jaw that is bulkier on one side.
Maintenance before events

Your visit
What to expect
1. Consultation & diagnosis
Your dermatologist examines the muscle while you clench, reviews previous toxin treatments and your goals, and photographs the lower face.
2. Injection
After cleansing and marking, 2–4 injection points per side are placed with a fine needle. The whole visit takes about 15 minutes.
3. Aftercare & follow-up
You can return to normal activity at once. A review at 4–6 weeks checks symmetry and adds a small top-up if needed.
Cost guide

Exact pricing is confirmed at consultation after examination.
Aftercare
Aftercare

- Expect visible slimming from week 3–4, with the full effect by week 6.

FAQ
Frequently asked questions
How long do jawline botox results last?
Typically 4–6 months. With regular treatment the muscle stays smaller for longer, and many patients extend the interval to 6–9 months.
Will my smile or speech change?
Not when the toxin is placed correctly in the lower masseter. Rarely, a temporary change in smile can occur if product spreads; experienced injectors minimise this.
Is Nabota as good as Botox?
Nabota is a Korean botulinum toxin type A with approvals in Korea, the US and EU. Clinical performance is comparable, and it is widely used in Seoul.
Can jawline injections treat teeth grinding?
Reducing masseter activity may ease bruxism and jaw tension, which is a common reason patients return.
Does it work if my jaw is bony?
Toxin only slims muscle. If the width is skeletal, fillers to refine the angle or lifting treatments may be suggested instead.
