Quick answer: The best non-surgical facial contouring treatments in Gangnam are jaw Botox to slim a square jaw, chin and jawline fillers to add projection and definition, HIFU or InMode to tighten the jawline and lower face, and thread lifts for a sharper V-line. Most visitors combine two of these, such as jaw Botox with chin filler, to balance the face without surgery or long downtime.
Key takeaways
- Non-surgical contouring works by slimming, adding, tightening or lifting, depending on your face shape.
- Jaw Botox slims gradually over several weeks; fillers show results immediately.
- Combining treatments usually gives a more balanced result than one alone.
- A facial assessment is essential, because the same "V-line" goal needs different treatments for different faces.
What is non-surgical facial contouring?
Facial contouring reshapes the proportions of the face, especially the jawline, chin and cheeks. In Korea, the soft "V-line" profile, with a slimmer lower face and defined chin, is a popular goal. Surgery can change bone structure, but many people achieve a noticeable improvement with injectables and energy devices, which have far less downtime and risk.
Which treatments are used for facial contouring?
Jaw Botox for a slimmer lower face
If your jaw looks wide because of a strong masseter muscle, Botox injected into the masseter relaxes the muscle so it gradually becomes smaller. The lower face looks slimmer over about four to eight weeks, and the treatment can also reduce clenching.
Best for: square jaw caused by muscle. Downtime: almost none.
Chin and jawline fillers for definition
Hyaluronic acid dermal fillers can add projection to a short or retruded chin and sharpen the jawline angle. A well-proportioned chin often makes the whole lower face look slimmer. See our facial filler page for more detail.
Best for: weak chin or soft jawline. Downtime: mild swelling for a few days.
Collagen stimulators for structure
Radiesse provides structure along the jawline and stimulates collagen gradually, giving a firmer, more defined contour over time.
HIFU and InMode for tightening the jawline
Sagging along the jaw blurs facial contours. Ultherapy, Shurink and other HIFU lifting treatments tighten deeper tissue, while InMode is often used to refine the jawline and under-chin area.
Best for: mild jowls or a soft jawline. Downtime: minimal.
Thread lifts for a sharper V-line
Thread lifts reposition sagging tissue along the cheeks and jaw for an immediate lift. They are often chosen when the goal is a sharper V-shaped lower face.
Best for: moderate sagging with a desire for immediate change. Downtime: swelling or tightness for one to two weeks.
How do you choose the right combination?
- Wide jaw from muscle: jaw Botox, sometimes with chin filler
- Short or receding chin: chin filler
- Soft jawline from sagging: HIFU or InMode, sometimes with a thread lift
- Flat profile: chin and jawline filler for definition
A skilled doctor looks at bone structure, muscle, fat and skin laxity together before recommending a plan. The goal is balance with your features, not an identical result for everyone.
How should you plan contouring around your trip?
- Book your consultation on day 1 or 2.
- Jaw Botox and energy devices can be done early, with little downtime.
- Allow a few days after fillers and one to two weeks after thread lifts before important events.
- Jaw Botox results appear after you return home, so plan a follow-up photo check with the clinic.
How long do results last?
As a general guide, jaw Botox lasts about four to six months, hyaluronic acid fillers in the chin and jaw commonly last a year or more, collagen stimulators last longer as collagen builds, and thread lifts last around one to two years. Energy-based tightening is usually maintained with yearly sessions.
