V-Line Contouring Injection in Seoul.
A consultation-led, non-surgical injectable approach to a slimmer, more tapered jawline and chin — combining chin filler for projection, jawline contouring with a structural or biostimulatory product, and sometimes submental fat-reducing injections. It is a soft-tissue and volume-based approach and does not reduce bone width or reshape the masseter muscle the way jaw-slimming Botox or surgical contouring can.
This page focuses specifically on injectable V-line contouring. LOUAVE also publishes dedicated pages for related approaches — including Jaw Slimming Botox, Chin Filler and Dermal Fillers — for readers comparing methods for jaw and chin contour.
Jawline & Chin Assessment
Chin projection and jawline tapering are frequently planned together so the lower face reads as one continuous line.
Duration varies by product used — HA filler, biostimulator or fat-reducing injection each follow a different timeline.
Planning accounts for your existing jaw and chin bone structure, since injectables reshape soft tissue, not bone.
Understanding V-Line Contouring Injection
Why the jaw and chin are planned as one line, not separate parts.
A V-line silhouette depends on how the chin, jawline and submental (under-chin) area relate to one another, not on any single feature alone. A retruded or short chin, a wide or square-reading jawline, and submental fullness can each contribute to a lower face that reads as wider or less tapered than a patient would like.
Injectable V-line contouring addresses these together: chin filler can add forward projection and narrow the chin's visual width, a jawline contouring product can soften a square angle, and submental fat-reducing injections can address fullness beneath the chin when present.
It is equally important to understand what this approach can and cannot do. It reshapes soft tissue and volume, and can meaningfully improve how tapered the lower face appears.
It cannot narrow the jaw bone itself or reduce a bulky masseter muscle — those are addressed differently, through jaw-slimming Botox or, in more significant cases, surgical options, both of which are reviewed separately from this page.
Plan the whole lower-face line, not one feature.
Rather than treating the chin, jaw and under-chin area as separate requests, they are assessed together, so the combination supports one continuous, natural taper rather than an isolated change that looks disconnected from the rest of the face.

Concept 01
Concept 02
Concept 03
Concept 04
Three zones, planned as one continuous taper.
A balanced V-line result depends on understanding how the chin, jawline and submental area relate to each other. During consultation, the doctor assesses projection, width and submental fullness together, then proposes which combination of injectables — and in what order — will create the most natural taper.
Chin Projection & Narrowing
HA filler placed along the chin can add forward projection and soften a wide or flat chin, narrowing the lower face's visual width.
Jawline Angle Softening
A structural or biostimulatory product placed along the jawline can soften a square angle and support a smoother taper toward the chin.
Submental Fullness Review
When fullness beneath the chin contributes to the lower face's width, fat-reducing injections may be discussed as part of the plan.
Proportion Check Before Treatment
Chin, jaw and submental zones are always reviewed together, so treatment supports one balanced line rather than one exaggerated feature.
Concerns V-Line Contouring May Address
Lower-face proportion concerns, reviewed together at consultation.
The concerns below relate to the chin, jawline and submental area as a group. Concerns caused mainly by masseter muscle bulk or by bone width are addressed differently and are explored on their own dedicated pages.
Retruded or Short Chin
A chin that sits behind the ideal facial profile line can be given forward projection, improving lower-face balance and taper.
Chin & JawWide or Flat Chin
A wide or flat chin contour can be visually narrowed with careful filler placement along the chin's edges and tip.
Chin & JawSquare-Reading Jaw Angle
A jaw angle that reads as square due to soft-tissue contour, rather than muscle bulk, may be softened with jawline contouring.
Chin & JawFullness Beneath the Chin
Submental fullness that adds visual width to the lower face may be discussed for fat-reducing injection alongside contouring.
Chin & JawAsymmetric Jawline or Chin
Mild asymmetry between the left and right jawline or chin can sometimes be visually balanced with tailored placement.
Chin & JawWanting a Softer, More Tapered Lower Face
Patients wanting a more tapered overall silhouette, without surgery, may discuss a combined chin-and-jaw contouring plan.
Chin & Jaw Treatment Philosophy
Understand the bone structure first, then contour with intention.
Because injectables reshape soft tissue rather than bone, the approach begins with an honest review of what your existing jaw and chin structure can and cannot achieve before any product is proposed.
Bone-Aware, Consultation-Led Planning
Chin, jaw and submental concerns are reviewed together against your existing bone structure before any products are proposed, so the plan is realistic rather than aspirational.
Whole lower-face assessment first
No default or one-size combination
Individualised, not formulaic
Structure before treatment
Preferred focus: realistic, proportion-aware planning
Sequenced, Product-Aware Combination
Chin filler, jawline contouring and submental treatment are staged and spaced according to each product's mechanism, rather than combined in one session by default.
Sessions spaced by product timeline
Reviewed before adding more
Compatibility checked in advance
Escalation considered later, not forced early

LOUAVE Treatment Process
A structured plan built around one balanced taper.
The process below is specific to injectable V-line contouring, from initial proportion assessment through to staged injection and immediate review.
Consultation & Proportion Assessment
The doctor examines chin projection, jawline angle and submental fullness together, and discusses realistic goals for a tapered lower face.
Whole lower-face assessmentProduct & Sequencing Plan
Chin filler, jawline contouring and, where relevant, submental treatment are proposed together with a session order confirmed at consultation.
Combined, sequenced planningStaged Injection Sessions
Each product is administered in its own appropriately spaced session, building the taper gradually rather than in one large combined visit.
Staged, spaced sessionsSymmetry & Line Review
The chin-to-jaw line and overall symmetry are checked after each session, before a broader review of swelling and shape follows over the coming days.
Immediate line & symmetry check Results & Development
Day 0
Week 1–2
Week 3–8
Ongoing
Visible from the first session, refined across the plan.
Chin and jawline filler effects are typically visible immediately after each session, though swelling can soften or overstate the taper for the first several days. When submental fat-reducing injections are part of the plan, their effect develops more gradually across multiple sessions rather than appearing right away.
First injection session
Chin and/or jawline contouring is typically addressed first, with the change in lower-face line visible immediately, alongside expected swelling.
Swelling resolves & review
Initial swelling and any bruising settle, and the doctor reviews the taper before confirming the next stage of the plan, if any.
Subsequent sessions
Any remaining products — jawline contouring or submental treatment — are introduced according to the sequencing plan.
Full taper settles
The complete V-line effect becomes fully visible as all sessions settle, with maintenance timing discussed per product used.
International patients planning a multi-session V-line combination should allow time in Seoul, or discuss a schedule spanning return visits, for staged sessions.
Suitability & Screening
Suitability is confirmed through an honest health review.
Treatment may be modified, delayed or declined when certain health factors are present, or when your goals are better served by jaw-slimming Botox or a surgical consultation instead.
V-line contouring injection may be discussed when:
- You feel your chin is short, retruded or flat, contributing to a less tapered lower face.
- You feel your jawline reads as wide or square due to soft-tissue contour rather than muscle bulk.
- You notice fullness beneath the chin that adds visual width to the lower face.
- You want a non-surgical, injectable approach and accept the more limited, soft-tissue-based change it can achieve compared with surgery.
- You understand this treatment does not narrow jaw bone width or reduce masseter muscle bulk.
Tell the doctor before treatment about:
- Pregnancy, planned pregnancy or breastfeeding.
- Any known allergy history, including to hyaluronic acid, other filler materials, fat-dissolving injection ingredients or anaesthetic products.
- Active infection or skin conditions near the chin, jaw or neck.
- Autoimmune conditions, keloid tendency, or a history of bleeding disorders and blood-thinning medication.
- Previous chin filler, jaw treatment, implants or surgery in this area, as altered anatomy affects planning and technique.
Aftercare
Simple precautions support a smooth taper.
Follow the instructions provided by the treating doctor after each session. Advice may vary according to which product was used at the chin, jawline or submental area.
Manage Swelling Gently
Use a cold compress as advised by the clinic, applied gently along the chin and jaw, to help reduce swelling after each session.
Avoid Pressure on the Jaw and Chin
Avoid sleeping on your front, applying strong facial pressure, or chewing very firm foods for the period advised by the clinic.
Keep Sessions on Schedule
Attend follow-up and subsequent sessions as planned, since the taper develops across the full sequence rather than one visit alone.
Avoid Strenuous Exercise
Skip intense exercise, saunas and heavy lifting for approximately twenty-four to forty-eight hours after each session.
Safety Information
General information, not a substitute for consultation.
This page provides general educational information about injectable V-line contouring. It does not replace an individual medical consultation, and effects, recovery and suitability vary between patients.
Seek immediate attention for:
- Skin blanching or whitening at or around the chin, jaw or submental area — this can be an early sign of vascular occlusion and requires immediate attention.
- Severe or disproportionate pain at any injection site, beyond the expected mild discomfort.
- Mottled or dusky discoloration spreading from a treated area — treat this as urgent.
- Difficulty breathing or swallowing, or significant swelling spreading toward the neck — seek emergency care immediately.
- Increasing redness, heat, discharge, fever, or lumps and significant asymmetry that do not settle within the expected timeframe for the product used.
Because chin, jawline and submental treatments each carry their own specific risk profile, signs of possible vascular compromise or a spreading reaction are treated with high urgency in this region. Contact the clinic immediately, or seek emergency care, if any of the above occurs — early recognition and prompt treatment, including hyaluronidase for HA-based products if needed, matter significantly here.
Frequently Asked Questions
Questions about V-line contouring injection.
Product selection, sequencing, expected timelines and suitability for chin and jaw contouring are confirmed during consultation.
What is V-line contouring injection?
V-line contouring injection is a non-surgical, consultation-led plan that combines chin filler, jawline contouring and sometimes submental fat-reducing injections to create a slimmer, more tapered lower-face silhouette.
How is this different from jaw-slimming Botox?
Jaw-slimming Botox reduces the bulk of an enlarged masseter chewing muscle. V-line contouring injection instead reshapes soft tissue and volume at the chin, jawline and submental area. The two are sometimes discussed together but work through different mechanisms.
Can this treatment make my jaw bone narrower?
No. Injectables reshape soft tissue and volume; they cannot narrow the underlying jaw bone. Patients whose primary concern is bone width are advised this treatment will not address it and may be referred for a surgical consultation.
Which products are commonly combined for V-line contouring?
Chin filler is most commonly paired with a jawline contouring product, and submental fat-reducing injections are added when under-chin fullness is present. The specific combination is proposed at consultation based on your anatomy.
How many sessions does V-line contouring usually take?
This varies by how many zones are treated and which products are used. A single-zone plan may be completed in one or two sessions, while a fuller chin, jaw and submental combination is typically staged across several sessions.
How long do the results last?
Duration depends on the product used at each zone — HA filler commonly lasts around nine to eighteen months, while biostimulatory and fat-reducing products follow their own separate timelines, discussed individually at consultation.
Does V-line contouring injection hurt?
Most patients describe brief, mild to moderate discomfort during injection. A topical numbing cream or the product's built-in local anaesthetic can help minimise sensation, and discomfort typically settles within a short period afterward.
What is the downtime after treatment?
Many patients return to normal activities the same or next day, though swelling and mild bruising around the chin and jaw are common and can be visible for several days to around one to two weeks while the final taper settles.
Is V-line contouring injection safe?
It can be performed safely by an appropriately experienced injector, but the chin, jaw and submental area each carry specific technique considerations. Risks exist and are discussed individually during consultation and covered in the safety information on this page.
Can V-line contouring be combined with jaw-slimming Botox?
Yes, the two are sometimes planned together when both muscle bulk and soft-tissue contour contribute to a wider lower face. Sequencing between the two is confirmed at consultation based on your specific anatomy.

Important treatment information
This page provides general educational information about injectable V-line contouring and does not replace an individual medical consultation. Chin filler, jawline contouring products and submental fat-reducing injections are distinct product categories with product-specific formulations, mechanisms, indications, contraindications and regulatory status that may vary by country. Injectable contouring reshapes soft tissue and volume; it does not narrow jaw bone width or reduce masseter muscle bulk, and is not a substitute for jaw-slimming Botox or surgical options when those are the more appropriate approach. Treatment must be selected and sequenced by an appropriately experienced medical professional after reviewing chin, jaw and submental anatomy, skin and soft-tissue quality, previous treatment or surgery in this area, health history, medications, allergies and informed consent. Temporary effects may include injection-site pain, redness, swelling, tenderness or bruising, which may occur after each session in a staged plan. Other possible effects include asymmetry, palpable lumps or nodules, and an unfamiliar appearance in or near the treated area. Rare but serious complications include vascular occlusion, skin necrosis, infection and delayed inflammatory reactions. Seek immediate medical care for skin that becomes unusually pale, dusky, mottled or increasingly painful, difficulty breathing or swallowing, signs of infection, or severe allergic symptoms. Results, symmetry, longevity, onset and maintenance requirements vary by product and by individual, and cannot be guaranteed.
