When facial contour and the V-line concern you
Care guide by concern
A blunt jawline and square-jaw impression arise from a combination of factors: hypertrophy of the masseter muscle, fat accumulation beneath the chin, and a descended SMAS layer. At DA Clinic Myeongdong, we use Botox to reduce the masseter, fat dissolving injections and Onda (microwave) to reduce submental and mandibular fat, and address any accompanying laxity with HIFU and RF — restoring a refined V-line impression.
See if this describes your condition
We first look into non-surgical ways to refine your contour, without shaving bone. The key is diagnosing whether muscle, fat, or sagging is the main cause and combining the procedures that fit. When you visit, we determine through palpation and observation of your expressions whether the main cause of the change in your lines is muscle, fat, or sagging. Since different causes call for different procedures, we propose a combination matched to the diagnosis rather than whatever procedure is trending.
If this sounds familiar
- My lower face looks wider in side and angled photos than from the front
- I tend to clench my jaw, and my jaw muscles feel firm
- Fullness under my chin makes my jawline look less defined
- I've looked into V-line procedures, but there are so many types it's confusing
Key Causes
- 01Masseter (chewing muscle) hypertrophy
- 02Fat accumulation under the chin and along the jawline

- 04Skeletal square jaw or a short lower face

Frequently Asked Questions
How long does the square-jaw Botox effect last?
The effect typically lasts 4–6 months. After 3–4 repeated sessions, cumulative atrophy of the masseter tends to extend the duration further. At DA Clinic Myeongdong, we measure masseter thickness to guide the appropriate dose.
What's the difference between square-jaw Botox and contouring treatments?
Square-jaw Botox addresses muscle volume, while contouring treatments address fat and line. The choice depends on whether the underlying cause is muscle or fat, and the two are sometimes combined.
Won't my face sag after the treatment?
Designing dosage and treatment areas conservatively may help reduce the concern of sagging. When sagging is already present, we first consider combining with a lifting treatment.
When do results become visible?
Botox typically develops gradually over 2–4 weeks, while fat-related treatments often appear over several sessions spaced weeks apart.
Results and recovery vary from person to person.
