Facial Asymmetry Treatment in Korea: Causes, Options and Costs
The short answer
Facial asymmetry in Korea is treated according to its cause: contouring or jaw surgery for uneven bone, Botox for one stronger chewing muscle, and filler or fat grafting for uneven volume. A Gangnam clinic usually starts with a facial analysis and CT scan. Typical 2026 costs range from about ₩300,000 for injections to ₩50,000,000 for two-jaw surgery, with downtime from none to about 6 weeks.
Key facts
- Common causes: jaw growth differences, muscle imbalance, volume loss, old injury
- Diagnosis: facial analysis, 3D CT, bite check
- Non-surgical: Botox, filler, fat grafting
- Surgical: contouring, genioplasty, orthognathic surgery, rhinoplasty
- Typical cost: about ₩300,000–₩50,000,000
- Realistic goal: balance, not perfect symmetry
What is facial asymmetry?
Facial asymmetry is an imbalance between the left and right sides of the face. Everyone has some, and slight differences are part of what makes a face look natural. It becomes a concern when one side of the jaw looks fuller, the chin points sideways, one cheek sits higher, the eyes or brows differ in height, or the smile tilts.
What causes it?
- Bone: uneven growth of the jaw or cheekbones, sometimes with a shifted bite.
- Muscle: one masseter larger from chewing on one side or clenching.
- Soft tissue: uneven fat, volume loss with age, or sagging on one side.
- Other factors: past injury, earlier surgery, nerve weakness or sleeping on one side.
Finding the cause is the most important step. In Gangnam, clinics typically combine photos, a 3D CT scan and a bite check before suggesting a plan.
Treatment options in Korea
1. Facial contouring surgery
When one jaw angle or cheekbone is larger, the surgeon reduces that side to match. This is done through incisions inside the mouth. See facial asymmetry correction for how procedures are combined.
2. Dermal fillers
Filler adds volume to the flatter side, for example the cheek, temple or jaw. It is quick, reversible and lasts about 6 to 18 months.
3. Botox (muscle balancing)
If one masseter is stronger, Botox on that side relaxes and slims it over a few weeks, evening out jaw width. It lasts about 4 to 6 months.
4. Rhinoplasty (if needed)
A crooked nose can make the whole face look uneven. Straightening it sometimes improves overall balance more than expected. See our crooked nose guide.
5. Combination treatments
Many patients need more than one approach: for example, two-jaw surgery for a tilted bite, then filler for fine-tuning.
Costs in Korea
| Treatment | Typical cost (2026) | Downtime |
|---|---|---|
| Botox balancing | ₩100,000–₩500,000 | None |

| Fat grafting | ₩2,000,000–₩6,000,000 | 1–2 weeks |
| Contouring or genioplasty | ₩5,000,000–₩20,000,000 | 2–4 weeks |
| Two-jaw surgery | ₩20,000,000–₩50,000,000 | 4–6 weeks |
How to check your own asymmetry
Phone cameras and mirrors can exaggerate differences, because a mirror flips your face and wide-angle lenses distort features near the edge. For a fairer view, take photos from about two metres away with the camera at eye level, in even light, looking straight ahead with a relaxed face. Take a second set while smiling and clenching. These photos help you explain your concern and help the clinic see whether the difference is in the jaw, cheeks, eyes or smile. Bring the same photos to every consultation so you can compare advice.
Why patients choose Korea
Korean contouring surgeons see a high volume of jaw and cheekbone cases, and 3D CT planning is routine in Gangnam clinics. Many clinics have international coordinators and offer combined consultations with surgeons and orthodontists in one visit, which helps when time in Seoul is limited.
Planning your trip
- Send clear front, side and smiling photos for an initial opinion before you fly.
- Expect a CT scan at your first visit if bone surgery is possible.
- Allow 1 to 2 days for injections, 2 weeks for contouring and 3 to 4 weeks for jaw surgery.
- Ask how follow-up will work once you are home.
How to choose a clinic
Look for a surgeon who explains the measured difference between sides, shows how each treatment addresses it and is honest about what will remain. Ask how many asymmetry cases they treat and whether a revision policy applies. Be cautious of plans that jump straight to the largest surgery without first explaining why smaller steps would not be enough.

Patient questions
Frequently asked questions
Is facial asymmetry normal?
Yes, mild asymmetry is normal. Treatment is considered when the difference is noticeable or bothers you.
Can filler fix facial asymmetry?
Filler can balance volume differences, but it cannot correct bone or bite problems.
Do I need jaw surgery?
Only if your bite or jaw position is significantly uneven. A CT scan and bite check will show this.
How long should I plan to stay in Seoul?
From a few days for injections to about 3 to 4 weeks for jaw surgery.
