Chin Asymmetry Correction in Korea: Centering the Lower Face
The short answer
Chin asymmetry in Korea is most often corrected with sliding genioplasty, which shifts the chin bone to the midline, while mild cases can be balanced with filler or Botox. Genioplasty takes about 1 to 2 hours under general anesthesia and typically costs ₩5,000,000 to ₩12,000,000. Filler costs about ₩300,000 to ₩700,000. If the bite is also tilted, jaw surgery may be needed.
Key facts
- Causes: uneven chin bone, jaw shift, muscle imbalance, soft tissue
- Main surgery: sliding genioplasty
- Other options: chin implant, filler, Botox, jaw surgery
- Typical cost: about ₩300,000–₩12,000,000
- Downtime: 1–2 days (filler) to 2–3 weeks (genioplasty)
- Diagnosis: CT scan and bite assessment
What is chin asymmetry?
Chin asymmetry means the chin is uneven in position, shape or projection. It may point to one side, be fuller on one side, or sit at a slight tilt. Because the chin is at the center of the lower face, even a few millimeters of deviation can make the whole face look off-balance.
Common causes
- Uneven growth of the chin bone
- A shifted lower jaw, often with a bite that does not meet evenly
- A stronger mentalis or masseter muscle on one side
- Uneven fat or soft tissue
- Previous injury or implant shift
Treatment options in Korea
1. Sliding genioplasty (chin surgery)
The surgeon cuts the lower chin bone and moves it sideways to the midline, and if needed forward, back, up or down. It is fixed with a small plate and done through the mouth. This is the most precise and permanent correction for bone-related asymmetry. Learn more about sliding genioplasty.
2. Chin implants
A custom-shaped implant can add more volume to the flatter side. Implants are best for mild asymmetry combined with a small chin. See chin augmentation.
3. Chin fillers (non-surgical)
Hyaluronic acid filler on the flatter side can even out minor differences. It lasts about 9 to 15 months and is reversible.
4. Botox (muscle adjustment)
Botox can relax an overactive chin muscle that pulls unevenly, or one stronger masseter that makes the jaw look tilted.
5. Combination treatments
When the whole lower jaw is shifted, a genioplasty alone may not be enough. Two-jaw surgery or one-sided jaw contouring may be combined.
Costs in Korea
| Treatment | Typical cost (2026) | Lasts |
|---|---|---|
| Chin filler | ₩300,000–₩700,000 | 9–15 months |
| Botox | ₩50,000–₩300,000 | 3–6 months |
| Chin implant | ₩2,500,000–₩6,000,000 | Long-term |
| Sliding genioplasty | ₩5,000,000–₩12,000,000 | Permanent |
| Two-jaw surgery | ₩20,000,000–₩50,000,000 | Permanent |
Recovery
Filler and Botox need almost no downtime. After genioplasty, expect swelling and a compression band for a few days, a soft diet for 2 to 4 weeks, and temporary numbness of the lower lip and chin. Most patients return to social activities in about 2 to 3 weeks and see the final result at around 6 months.
Is the problem the chin or the whole jaw?
This is the key question at consultation. If your teeth meet evenly and only the chin is off-center, chin surgery or filler can usually correct it. If your upper and lower midlines do not line up, your bite feels uneven, or your whole lower jaw tilts, the asymmetry starts in the jaw itself. Correcting only the chin in that case can leave the jawline uneven. A CT scan, dental check and photos of your bite help decide which level needs treatment.
Risks to discuss
Ask about lower lip and chin numbness, residual asymmetry, a step at the edge of the moved bone, implant shifting, and infection. For filler, ask how much will be placed on each side and whether a review is included.
Why patients choose Korea
Gangnam clinics routinely use 3D CT planning for chin and jaw procedures, allowing precise measurements of how far the chin is off-center. Many contouring surgeons perform genioplasty frequently, and coordinators can arrange consultation, CT and surgery within a short trip.
How to choose a clinic
- Ask to see the measured deviation on your CT scan.
- Ask whether your bite affects the plan.
- Ask how the surgeon prevents soft tissue sagging after bone movement.
- Confirm follow-up arrangements if you live abroad.
Questions to ask at consultation
Ask how many millimetres your chin is off-center, whether the plan moves bone, adds volume or relaxes muscle, and how the result will look from the front and in profile. Ask whether the clinic offers a 3D simulation and how a small residual difference would be handled after healing.

Patient questions
Frequently asked questions
Can filler correct a crooked chin?
Filler can mask mild asymmetry by adding volume to one side, but it cannot move the bone to the center.
Is genioplasty painful?
It is done under general anesthesia. Afterwards, discomfort is usually moderate and controlled with medication.
Will I need braces?
Only if your bite is also uneven and jaw surgery is planned.
How long should I stay in Korea for genioplasty?
About 10 to 14 days.
