Weak Chin Treatment in Korea: Filler, Implant or Bone Surgery
The short answer
A weak chin in Korea is treated with chin filler for mild cases, a silicone chin implant for moderate projection, or a sliding genioplasty that moves your own bone forward for larger or more complex changes. Typical 2026 costs are about ₩300,000 to ₩700,000 for filler, ₩2,500,000 to ₩6,000,000 for an implant and ₩5,000,000 to ₩12,000,000 for genioplasty, with 1 day to 3 weeks of downtime.
Key facts
- Signs: chin sits behind the lips in profile, soft jaw-neck line
- Mild cases: chin filler, lasts about 9–15 months
- Moderate cases: silicone chin implant
- Larger or complex: sliding genioplasty
- Typical cost: about ₩300,000–₩12,000,000
- Downtime: 1 day (filler) to 2–3 weeks (genioplasty)
What is a weak chin?
A weak chin, also called a recessed chin or microgenia, is a chin that lacks projection or size. In profile, it sits behind an imaginary line dropped from the lower lip. A weak chin can make the nose look larger, the lips look fuller or more forward, and the jaw and neck look less defined.
Common causes
- Natural chin bone size and shape
- A lower jaw that is set back, sometimes with an overbite
- Soft tissue changes with age
- Weight gain under the chin, which can make a chin look weaker
Treatment options in Korea
1. Chin augmentation surgery (implant or sliding genioplasty)
Implant: a silicone implant is placed on the chin bone through a small incision inside the mouth or under the chin. It is quick, usually 30 to 60 minutes, and gives a predictable forward change.
Sliding genioplasty: the chin bone is cut and moved forward, and if needed down or sideways, then fixed with a plate. It suits larger changes, long or short chins, and patients who prefer no implant. Compare both in our chin augmentation guide and our page on sliding genioplasty.
2. Chin fillers (non-surgical)
Firm hyaluronic acid filler adds projection and a little length in about 20 minutes. It is ideal if you want a small change, are unsure about surgery or want to preview the effect. See chin filler.
3. Combination treatments
A weak chin often comes with fullness under the chin. Chin liposuction or fat-dissolving injections can be combined to sharpen the jaw-neck angle. Some patients also combine chin augmentation with rhinoplasty for profile balance.
Comparing your options
| Option | Typical cost (2026) | Change possible | Lasts | Downtime |
|---|---|---|---|---|
| Chin filler | ₩300,000–₩700,000 | Small | 9–15 months | 1 day |
| Chin implant | ₩2,500,000–₩6,000,000 | Moderate | Long-term | 1–2 weeks |
| Sliding genioplasty | ₩5,000,000–₩12,000,000 | Moderate to large | Permanent | 2–3 weeks |
When the problem is the jaw
If your whole lower jaw is set back and your bite does not meet properly, chin surgery alone may only hide the issue. An orthodontic and jaw assessment can show whether jaw surgery would treat the cause.
Recovery
- Filler: mild swelling for a day; avoid pressing the chin for a week.
- Implant: swelling and tape for a few days; soft diet; back to normal in 1 to 2 weeks.
- Genioplasty: more swelling, a chin band and temporary lip numbness; social downtime about 2 to 3 weeks.
Risks to discuss
With filler, the main issues are bruising, a widened chin if too much is used, and gradual migration. With implants, ask about shifting, infection, a visible edge and slow bone wear under the implant over many years. With genioplasty, ask about lower lip and chin numbness, asymmetry and a step at the jaw border. For any option, the most common regret is a change that is too large or too small, so agree on a clear target before treatment.
Planning your trip
Filler fits into a day or two. An implant needs about a week in Seoul, and genioplasty 10 to 14 days. Bring soft foods, lip balm and an alcohol-free mouthwash, and avoid scheduling photos for a couple of weeks after surgery.
Questions to ask at consultation
Ask how many millimetres of projection each option can add, how the change will look in profile, and whether your bite or nose shape affects the plan. If an implant is suggested, ask about its material, size and how it is fixed so it does not shift.
Why patients choose Korea
Chin augmentation is very common in Gangnam, often combined with V-line or nose surgery. Clinics typically offer CT scans and 3D simulation on the day of consultation, helping international patients decide quickly.

Patient questions
Frequently asked questions
What is the best treatment for a weak chin?
It depends on how much change you need. Filler suits mild cases, implants moderate cases and genioplasty larger or complex cases.
Is a chin implant noticeable?
A well-sized, well-placed implant looks and feels natural. The incision is usually inside the mouth.
Can I try filler before surgery?
Yes. Many patients use filler to preview the look before committing to an implant or genioplasty.
How long should I stay in Seoul?
A day or two for filler, about a week for an implant and 10 to 14 days for genioplasty.
