Quick answer

What is jawline slimming?

Jawline slimming is a non-surgical way to narrow a wide or square lower face. The main tool is botulinum toxin injected into the masseter muscle, which gradually shrinks an enlarged chewing muscle; fat-dissolving injections or HIFU are added when soft tissue, not muscle, causes the width.

It is one of the most requested treatments in Seoul for the V-line look, and it can also ease teeth clenching. The doctor feels the jaw while you bite to tell muscle from fat — see masseter Botox for the muscle side in detail.

Your visit

How Jawline Slimming works at Umi

Every visit is doctor-led and explained in English, from the first skin check to aftercare.

  1. Bite & jaw check

    The doctor palpates the masseter while you clench to judge muscle size versus fat.

  2. Plan the mix

    Toxin dose is set per side; fat reduction or HIFU is added if needed.

  3. Injections

    A few precise injections into each masseter; extra treatment along the jaw if planned.

  4. Aftercare

    Do not massage the jaw or lie down for 4 hours; avoid saunas that day.

Before & after

How jawline slimming narrows the lower face

A relaxed masseter slowly reduces in bulk, so the angle of the jaw looks softer and the face tapers to the chin.

Illustration of the mechanism — not a patient photo. Individual results vary; real before-and-after photos can be reviewed at consultation.
Week 1–2

Chewing hard foods may feel slightly weaker.

Weeks 4–6

The jaw angle starts to look narrower.

Weeks 6–8

Maximum slimming; repeat at 4–6 months.

Is it right for you?

Who Jawline Slimming suits best

Good fit if you…

  • Have a wide, square jaw from strong chewing muscles
  • Clench or grind your teeth
  • Want a softer V-line without surgery
  • Can wait a few weeks for gradual results

Consider another option if…

  • Your jaw width is mainly bone — that needs a surgical opinion
  • You are pregnant or breastfeeding
  • You have a neuromuscular disorder
  • You have very thin cheeks that could look hollow with slimming

Recovery & results

What to expect, step by step

  1. Same day

    Small injection marks only; normal activity straight away.

  2. 1–2 weeks

    The muscle starts to relax; chewing tough food feels easier to tire.

  3. 4–8 weeks

    Visible slimming of the lower face.

  4. 4–6 months

    Repeat to keep the muscle smaller; intervals often lengthen over time.

FAQ

Jawline Slimming questions

How many sessions do I need?

One session shows a change, but two or three sessions spaced about 4–6 months apart usually give a more lasting reduction.

Will it affect my smile?

Placed correctly in the masseter it should not. Injecting too far forward can affect smile muscles, which is why mapping matters.

Is it safe for teeth grinding?

Yes. Masseter botulinum toxin is widely used to reduce clenching and jaw tension.

Can I combine it with filler?

Yes. A little chin filler often enhances the V-line effect after slimming.

Do foreigners pay more?

No. International patients pay the same price as local patients at Umi Clinic.
