🌸 Quick answer

What are V Line injections? V Line injections are a combination of non-surgical treatments that slim and define the lower face. Masseter Botox relaxes bulky jaw muscles, fat-dissolving injections reduce jowl or lower-cheek fat, and optional jawline filler adds definition. Together they create a sharper, more tapered V-shaped contour. The approach is tailored to what is causing the width, and most people see their full result within four to eight weeks.

What are V Line injections?

V Line injections are a tailored mix of injectables that target the different causes of a wide or heavy lower face. They often combine masseter Botox to reduce muscle bulk, fat-dissolving injections to slim fat pockets, and sometimes jawline filler to add definition.

Because the width of a jaw can come from muscle, fat or bone, a doctor first checks what is driving it, then selects the right combination; injections cannot change bone structure.

What it targets

  • Wide or strong jaw muscles
  • Lower-face and jowl fullness
  • A soft or undefined jawline
  • Facial proportions and balance
  • Mild asymmetry

How it works

  • Masseter Botox slims muscle over weeks
  • Fat-dissolving injections reduce fat
  • Filler sharpens the jawline where needed
  • Combined for a tapered V-line

Before & after: what changes

The lower face slims gradually over the weeks as muscle relaxes and fat reduces.

Who are V Line injections for?

A good fit if you

  • Have a wide jaw from strong chewing muscles
  • Have mild jowl or lower-cheek fullness
  • Want a softer, more defined jawline
  • Want fast results without surgery

Less suitable if you

  • Have width from bone structure alone (surgery needed)
  • Have significant sagging (consider a V-line thread lift)
  • Are pregnant or breastfeeding

How V Line injections work, step by step

  1. Consultation & facial mapping

    The doctor assesses muscle strength, fat and jaw symmetry to find what causes the width.

  2. Customised plan

    Your treatment may combine masseter Botox, fat-dissolving injections and jawline filler.

  3. Quick procedure

    Injections are placed precisely; most sessions take 10–20 minutes with minimal discomfort.

Recovery and results timeline

Downtime is minimal. Mild swelling, tenderness, small bruises or slight chewing fatigue from masseter Botox may appear and settle within a few days.

  1. Day 0 Filler definition is immediate
  2. 2–3 weeks Botox slimming begins
  3. 4–6 weeks Fat reduction and contour change
  4. 4–8 weeks Full V-line transformation

V Line injections at a glance

Cost depends on the combination and amounts used. International patients pay the same local price, confirmed at consultation.

Components Masseter Botox, fat-dissolving injections, optional filler
Session time 10–20 minutes
Downtime Minimal
Masseter Botox lasts 4–6 months
Fat reduction Long-lasting once fat cells clear
Jawline filler 12–18 months
Cost Confirmed at consultation; international patients pay the same local price

How the combination is tailored

Not everyone needs all three components. If the jaw is wide mainly from muscle, masseter Botox alone may be enough. If there is extra fat under the chin, fat-dissolving injections are added, and filler is used only when more definition is wanted. Your doctor builds the plan around your anatomy.

V Line Injections FAQ

How long do V Line injection results last?

It depends on the components. Masseter Botox lasts about four to six months, fat reduction is long-lasting once fat cells clear, and jawline filler lasts twelve to eighteen months. Yearly maintenance keeps a consistent shape.

Do V Line injections hurt?

Discomfort is usually mild, described as quick pinches. Numbing can be used. Brief swelling, tenderness or chewing fatigue may follow.

Can injections slim a jaw that is wide from bone?

No. Injections relax muscle and reduce fat but cannot change bone. A doctor will tell you honestly whether muscle, fat or bone is causing the width.

When will I see the V-line result?

Filler definition is immediate, masseter slimming begins around two to three weeks, and the full transformation usually appears within four to eight weeks.

Is this the same as jaw Botox?

Jaw Botox is one part of it. Jaw Botox relaxes the masseter, while V Line injections may add fat-dissolving injections and filler for a fuller contouring effect.

Can I have it during a short trip to Seoul?

Yes. The injections take minutes with minimal downtime, though the slimming develops over the following weeks after you travel home.
