The Korean V-line is a slimmer, tapered lower face with a clean jawline. This guide explains which non-surgical treatments create it, how to match them to your face, and how to plan them during a trip to Seoul.
Korean V-line lifting is a non-surgical approach to a slimmer, more defined lower face. Doctors combine treatments based on the cause: jaw Botox for a bulky chewing muscle, HIFU or RF for loose skin along the jawline, fat-dissolving injections, InMode Mini FX or ONDA for under-chin fat, chin filler for projection, and thread lifts for jowls. At Dernia Clinic Myeongdong in Seoul, jaw Botox starts from ₩59,000 with a Korean toxin, Shurink Universe from ₩149,000 for 300 shots and fat-dissolving injections from ₩69,000 per area (KRW, excluding 10% VAT).
Prices are in Korean won, exclude 10% VAT and are confirmed by a doctor at consultation.
What is the Korean V-line?
In Korean aesthetics, the V-line describes a lower face that tapers smoothly from the cheekbones to a slim, softly pointed chin, with a clear jawline and no heaviness under the chin. Surgery can reshape bone, but most people visiting Seoul are looking for a non-surgical way to refine their jawline that looks natural and requires little downtime.
Non-surgical V-line lifting does not change bone. Instead, it addresses the soft-tissue reasons a jawline looks wide, heavy or undefined. Dernia does not perform jaw or chin surgery or chin implants; this guide focuses on non-surgical options.
Why does the jawline lose definition?
A good plan starts by identifying the cause. Most people have more than one.
| Cause | How it looks | Common non-surgical option |
|---|---|---|
| Large masseter (chewing) muscle | Square, wide lower face | Jaw Botox |
| Loose skin and SMAS | Soft jawline, early jowls | HIFU (Ulthera, Shurink) or RF |
| Fat under the chin or along the jaw | Double chin, heavy lower face | Fat-dissolving injection, InMode Mini FX, ONDA |
| Small or recessed chin | Jawline blends into the neck | Chin filler |
| Descended tissue | Jowls, broken jawline | PDO thread lift |

V-line treatment options in Seoul
Jaw Botox for a square jaw
Jaw Botox relaxes the masseter muscle at the angle of the jaw. As the muscle becomes less bulky over two to four weeks, the lower face tapers into a softer shape. It also helps some people who clench. Results last about four to six months. See the jaw Botox page.
HIFU and RF for jawline lift
Focused ultrasound such as Shurink Universe or Ulthera Prime lifts the deeper supporting layer along the jawline, while RF tightens the skin. These are the core of V-line lifting when the issue is laxity rather than width.
Fat reduction for the double chin
Fat-dissolving injections, InMode Mini FX and ONDA can each reduce localized fat under the chin or along the jowls. Injections usually need two to four sessions and cause a few days of swelling; energy devices cause less swelling but results also build over weeks.
Chin filler for projection
A small amount of hyaluronic acid filler can lengthen or project the chin, which visually sharpens the jawline and balances the profile. It is immediate and adjustable.
Thread lift for jowls
PDO threads reposition tissue along the jawline for a more immediate lift, with a few days of swelling or bruising. See the thread lift page.
Who is a good candidate for V-line lifting?
Usually a good fit
- A wide lower face from strong chewing muscles
- Mild jowls or a soft jawline
- Small pockets of fat under the chin
- A slightly short or recessed chin
- People who want a natural, gradual change
Talk to the doctor first
- Width mainly from bone structure (surgery may be the only way to change it)
- Pregnancy or breastfeeding
- Neuromuscular conditions (for Botox)
- Bleeding disorders or blood thinners (for injections and threads)
- Very slim faces, where fat reduction or HIFU could cause hollowing
How a V-line plan is put together
- Assessment. The doctor feels the masseter while you clench, checks skin laxity and fat, and looks at chin projection from the side.
- Prioritize. The main cause is treated first. For many visitors, that is jaw Botox or HIFU.
- Add refinements. Fat reduction or chin filler is added where it makes a visible difference.
- Sequence the day. Energy devices are usually done before injectables on the same day.
- Plan follow-up. Botox is repeated every four to six months, and HIFU or fat reduction may need a series.
Many people choose a bundled approach such as the V-Line Contour Package.
V-line results timeline
- Immediately: chin filler shows right away; HIFU may give a subtle early lift.
- Weeks 2–4: jaw Botox slimming becomes visible as the muscle relaxes.
- Weeks 4–8: fat reduction and collagen remodeling become noticeable.
- Months 2–3: combined result is usually at its best.
Most people's final V-line result appears after they have returned home, so take clear front and side photos before treatment.
Keeping your V-line result
Jawline definition is affected by more than treatment. Stable weight helps preserve fat-reduction results, while significant weight gain can soften them. If you clench or grind your teeth, jaw Botox may need repeating on a regular schedule to keep the masseter from rebuilding bulk. Good posture, particularly avoiding long periods looking down at a phone, can make the under-chin area look less full in everyday life. Daily sunscreen protects the collagen built by HIFU and RF. Most people plan a maintenance visit every four to twelve months, depending on which treatments they had, and many combine it with a return trip to Seoul.
Risks and side effects of V-line treatments
Each treatment carries its own risks. Jaw Botox can cause temporary chewing fatigue, mild bruising and, uncommonly, an uneven smile if toxin spreads to nearby muscles. HIFU can cause tenderness, temporary nerve irritation and unwanted fat loss in slim faces. Fat-dissolving injections commonly cause swelling, tenderness and bruising for several days, and rarely nodules or nerve irritation. Thread lifts can cause bruising, asymmetry, dimpling and, rarely, infection.
Chin filler carries the general filler risks of swelling, bruising and lumps, and a small but serious risk of vascular occlusion, where filler blocks a blood vessel. This needs urgent treatment, so filler should only be injected by an experienced doctor who has dissolving agents on hand. Read side effects and when to contact us.
Flying home soon? Jaw Botox and HIFU rarely affect travel. If you have filler, fat-dissolving injections or threads, allow a few days for swelling to settle. See our guide to flying after injectables.

Planning V-line treatments around your Seoul trip
- Book ahead. Send front and side photos with your dates through our consultation form.
- Avoid your arrival day. Rest first; start treatment on day two.
- Getting here. Dernia is in Myeongdong, near Myeongdong Station (Line 4) and Euljiro 1-ga Station (Line 2).
- Plan follow-up at home. Botox and some fat-reduction plans need repeat sessions, so ask how to continue after your trip.
Frequently asked questions
Can I get a V-line without surgery?
Yes, if your jawline width or heaviness comes from muscle, fat or loose skin. If width comes mainly from bone, non-surgical treatment can only soften it.
How long does jaw Botox take to slim the face?
Slimming usually becomes visible over two to four weeks and lasts about four to six months.
What is the fastest V-line treatment?
Chin filler shows immediately, and a thread lift gives a visible lift on the day. Botox, HIFU and fat reduction build gradually over weeks.
Can I combine jaw Botox and HIFU on the same day?
Often, yes. The doctor usually performs the energy treatment first and then the injection, and confirms the plan at consultation.
Does Dernia offer chin implants or jaw surgery?
No. Dernia offers non-surgical contouring only, such as Botox, filler, energy devices, fat-dissolving injections and threads.
Is chin filler safe?
It is commonly performed but carries risks, including a rare risk of vascular occlusion. It should be done by an experienced doctor prepared to treat complications immediately.
Want a more defined jawline in Seoul?
Send front and side photos with your travel dates. A doctor examines you in person, explains V-line options in English and confirms your plan and price before treatment.
