Quick answer: A "V-line" face has a slim lower face and a soft, pointed chin. In Korea, non-surgical V-line treatments include jaw Botox, chin filler, fat reduction under the chin, and lifting with HIFU, radiofrequency or threads. The right choice depends on whether your face is wide from muscle, fat, sagging or a short chin.
Key takeaways
- V-line means a slim jaw and a defined chin, a popular look in Korea.
- Non-surgical options change muscle, fat, skin and chin shape, not bone.
- Jaw Botox and chin filler are the most common starting points.
- Fat reduction and lifting help when the lower face is full or sagging.
- A combination plan usually gives the most natural V-line result.
What is a V-line face?
A V-line face narrows gently from the cheekbones to the chin. The jaw looks slim from the front, the jawline is clear from the side, and the chin is balanced with the nose and lips. The look became popular in Korea and is now requested by many international visitors.
Korea treated about 2.01 million foreign patients in 2025, and around 63% came for dermatology, according to the Ministry of Health and Welfare. Lower-face treatments are among the most common requests.
Step 1: find out why your lower face looks wide
- Muscle: strong jaw muscles make the face square, especially when you clench.
- Fat: fullness under the chin or along the jaw.
- Sagging: jowls and loose skin blur the jawline.
- Chin shape: a short or flat chin makes the face look rounder.
A good doctor checks all four before suggesting treatment. Our article on what a facial assessment should include explains this step.
Step 2: match the treatment to the cause
Jaw Botox for muscle
Relaxes the jaw muscle so the face slowly looks slimmer over four to eight weeks. See Botox in Gangnam.
Chin filler for shape
Adds length and a soft point to the chin, which makes the whole face look more V-shaped. See dermal fillers in Seoul.
Fat reduction for fullness
Radiofrequency devices such as InMode or fat-dissolving injections reduce small fat pockets under the chin and along the jaw.
Lifting for sagging
HIFU (such as Ultherapy or Shurink), RF devices and thread lifts tighten and lift the lower face. See the Korean thread lift guide and treatments for jowls.
Popular V-line combinations
- Jaw Botox + chin filler: slimmer jaw and better chin shape. A classic first plan.
- HIFU + jaw Botox: lifting plus slimming for people in their 30s and 40s.
- InMode + chin filler: less fat under the chin and a sharper profile.
- Threads + filler: stronger lift with added definition.

How much downtime should I expect?
- Jaw Botox: almost none.
- Chin filler: mild swelling for one to three days.
- HIFU: mild tenderness or swelling for a few days.
- InMode or threads: swelling for about a week.
If you have a short trip, start with low-downtime options. See low-downtime treatments before flying.
When will I see results?
- Filler: straight away.
- Jaw Botox: four to eight weeks.
- HIFU and RF: gradual over two to three months.
- Threads: immediate lift, improving as swelling settles.
How to choose the right clinic
- Look for a doctor who explains why each treatment is suggested.
- Ask for a written plan and quote, with brands and amounts.
- Make sure the doctor who consults you also performs the treatment.
- Avoid plans that sell many treatments you do not need.

Frequently asked questions
Can I get a V-line face without surgery?
Yes, a softer V-line is possible without surgery. Bone shape cannot change, but muscle, fat, skin and chin shape can.
Which V-line treatment works fastest?
Chin filler gives the fastest visible change. Jaw Botox takes a few weeks.
Is V-line right for everyone?
No. The goal is balance with your own features, not the same face for everyone.
How long do V-line results last?
It depends on the treatment. Filler often lasts 12 to 18 months, and jaw Botox four to six months.
