A defined jawline does a lot of quiet work in how a man's face reads. It frames the lower third, separates the face from the neck, and tends to be one of the first things people notice in a profile photo or on a video call. So it is understandable that more men are asking what can actually be done about a jaw that looks soft, short, or undefined, and what it costs to do it well in Bangkok.
The honest answer is that "jawline contouring for men" is not one procedure. It is a family of treatments, some injectable and reversible, some surgical and permanent, that target slightly different problems. A man whose jaw looks soft because of a heavy chewing muscle needs something completely different from a man whose chin sits too far back, who in turn needs something different from a man carrying a pad of fat under the chin. Getting a good result is mostly about matching the right tool to the right anatomy, which is why an in-person assessment matters more than any price list.
This guide walks through the options the way an experienced clinician would think about them: what each technique does, who it suits and who it does not, realistic Bangkok pricing in both Thai baht and US dollars, recovery, risks, and how to tell a safe clinic from a risky one. None of this is a substitute for a consultation. Every treatment described here is a medical procedure, and the prescription-only ones (botulinum toxin, dermal fillers, anything surgical) legally require an assessment and, where relevant, a prescription from a licensed doctor.
What "jawline contouring" actually means for men
Jawline contouring is an umbrella term for procedures that sharpen and strengthen the lower face: the chin, the body of the jaw, the angle of the jaw near the ear, and the transition between jaw and neck. The goal in men is usually a squarer, more defined lower face with a clear shadow line under the jaw, rather than the softer, more tapered "V-line" that tends to be marketed to women.
That distinction is not just cosmetic preference. The male jaw is, on average, wider at the angle, has a sharper, less obtuse gonial angle than the female mandible, and pairs with a taller, more projected chin. A technique or injection pattern designed to slim and narrow a face can feminize a man's lower third if it is applied without that male anatomy in mind. The skill is as much in restraint and direction as in volume.
Broadly, the options fall into two groups:
Non-surgical (injectable): masseter botulinum toxin to slim or balance a heavy jaw muscle, and hyaluronic acid (HA) or calcium-based fillers to add structure to the chin and jaw angle. Temporary or reversible, minimal downtime.
Surgical: chin implants or sliding genioplasty to project the chin, jaw angle implants to widen and square the back of the jaw, submental (under-chin) liposuction to clean up the jaw-neck line, and occasionally bone reshaping. Permanent, with real recovery.
Many men end up with a combination, because the jawline is a system. A stronger chin can look unbalanced without addressing fullness under it, and a slimmer jaw muscle can reveal that the chin was always slightly weak.
The options, technique by technique
Masseter botulinum toxin (jaw-slimming or balancing injections)
The masseter is the thick chewing muscle at the back angle of the jaw. In some men, especially those who clench or grind, it is enlarged enough to make the lower face look wide, square in a boxy rather than chiselled way, or asymmetric. Botulinum toxin injected into the muscle reduces its activity, and over weeks the muscle thins, softening the angle.
In a six-month study of masseter botulinum toxin, the lower-third reduction peaked at roughly 12% at around 12 weeks before partially returning as muscle function recovered, which fits what is seen in practice: visible change within a month, a peak at two to three months, and a need to repeat every four to six months at first (Klein et al., 2014). For men, the aesthetic decision is nuanced. Over-thinning a masseter can narrow a face that looks better square, so a good injector often treats asymmetry or excess bulk rather than chasing maximum slimming. Ultrasound-guided injection is increasingly used to place the toxin accurately within the muscle and reduce side effects such as an uneven smile or paradoxical bulging (Ryoo et al., 2024; Popescu et al., 2024).
Dermal fillers for the chin and jaw angle
Fillers add structure where bone projection is lacking. A stiff hyaluronic acid filler, or a calcium hydroxylapatite product such as Radiesse, can be placed along the jawline, at the angle, and on the chin to sharpen the border, lengthen a short chin, or build the back of the jaw. It is an in-office treatment, usually 15-30 minutes, with results visible immediately and the option to dissolve HA filler with hyaluronidase if the result is not what you wanted.
A systematic review of HA chin augmentation across more than 2,200 patients found high satisfaction and a mean duration of effect around 13 months, with most side effects being minor and transient (bruising, swelling, tenderness) and serious complications rare (Al-Khafaji et al., 2023). Fillers suit men who want definition without surgery, who are testing a shape before committing to an implant, or who need a modest correction. They do not suit men who need a large amount of projection, where the volume of filler required becomes impractical and expensive over time.
Chin augmentation: implant versus sliding genioplasty
A weak or recessed chin is one of the most common reasons a man's jawline looks undefined, because the chin anchors the whole lower face. There are two surgical ways to fix it.
An alloplastic chin implant is a pre-shaped silicone, Medpor, or Gore-Tex piece placed over the chin bone through a small incision inside the mouth or under the chin. A sliding genioplasty cuts the chin bone and moves the front segment forward (or down, or sideways), then fixes it with a small plate. Implants are simpler, faster, and reversible; genioplasty moves your own bone and handles larger or more complex corrections.
Both work well. A systematic review of more than 1,100 patients found high satisfaction with both, a trend toward slightly higher satisfaction and more predictable soft-tissue change with osseous genioplasty, and higher infection and reoperation rates with implants (Kauke-Navarro et al., 2025). On implant material specifically, a review of more than 3,000 patients found overall complications uncommon and broadly similar between silicone, Medpor, and Gore-Tex, with silicone showing the lowest rate in that dataset (Liao et al., 2022). The choice between implant and genioplasty is a consultation decision based on how much movement you need and your own risk preferences.
Jaw angle implants
To widen and square the back of the jaw, custom or pre-formed implants can be placed over the mandibular angle, usually through incisions inside the mouth. This is the procedure that most directly creates the wide, masculine, "two-corner" lower face some men want. It is more specialized than chin work, demands a surgeon experienced in male facial structure, and carries the same implant considerations around infection, shifting, and asymmetry. It is not a high-volume procedure at most clinics, so surgeon selection matters even more here.
Submental liposuction and the jaw-neck line
Fat under the chin blurs the jawline regardless of how good the bone structure is. Submental liposuction removes a pad of fat through a tiny incision, sharpening the jaw-neck transition and the shadow under the jaw. In men with good skin elasticity, it can meaningfully clean up the lower face on its own or alongside chin work. It does not tighten loose skin, so men with significant skin laxity may need a neck lift instead, which is a larger operation and a different conversation.
Buccal fat reduction
Removing a portion of the buccal fat pad reduces lower-cheek fullness and can make the jawline look more defined by contrast. It is worth a cautious note for men: cheek fullness in youth often becomes welcome facial volume with age, and over-aggressive buccal fat removal can produce a gaunt, prematurely aged look later. It is a reasonable option for the right face and a regrettable one for the wrong face, so it deserves a careful, conservative assessment.
Bangkok pricing: THB, USD, and how it compares to the West
The single biggest reason men travel to Bangkok for this work is cost. Comparable jawline procedures commonly run 60-80% less than in the United States, the United Kingdom, or Australia, where a jaw or chin implant procedure can reach 8,000-13,000 USD, while Bangkok clinics deliver similar work with experienced surgeons at a fraction of that.
The figures below are indicative ranges gathered from Bangkok clinics and medical-tourism platforms as of early 2026. Real quotes vary with the surgeon's seniority, the clinic, implant brand and whether it is custom, anaesthesia type, and what the package includes. Always confirm the exact figure and inclusions at your consultation.
Procedure | Bangkok price (THB) | Bangkok price (USD)* | Typical US / UK / AU price (USD) | Indicative saving |
Masseter Botox (jaw slimming) | 8,000-25,000 | 240-760 | 600-1,500 | ~50-65% |
Jawline / chin filler (HA or Radiesse) | 12,000-75,000 | 360-2,270 | 1,200-4,000+ | ~55-70% |
Submental (under-chin) liposuction | 40,000-90,000 | 1,210-2,730 | 3,000-6,000 | ~55-65% |
Chin implant (alloplastic) | 40,000-110,000 | 1,210-3,330 | 4,000-8,000 | ~60-70% |
Sliding genioplasty (bone) | 90,000-150,000 | 2,730-4,550 | 6,000-12,000 | ~55-65% |
Jaw angle implants | 75,000-180,000 | 2,270-5,450 | 8,000-13,000 | ~60-76% |
*USD converted at roughly 33 THB to 1 USD; the rate moves, so treat dollar figures as approximate. Ranges are indicative, not quotes. Confirm pricing at consultation.
A few things worth understanding before you read too much into any single number. Non-surgical pricing is often quoted per unit (Botox) or per syringe or cc (filler), so a "from" price can climb quickly once you account for the volume a male jawline actually needs. Surgical "packages" may or may not include the implant, anaesthesia, the hospital or clinic stay, medications, the compression garment, and follow-up visits. A cheaper headline price with the implant and anaesthesia billed separately can end up costing more than a higher all-inclusive quote.
What actually drives the cost
Surgical versus non-surgical. Theatre time, anaesthesia, and an operating team make surgery the larger line item; injectables are priced on product and the injector's expertise.
Surgeon seniority and specialization. A surgeon who does male facial contouring regularly will usually charge more, and is usually worth it for irreversible work.
Custom versus stock implants. A custom implant designed from your CT scan costs more than a pre-formed one but can fit better for complex cases.
Product brand and volume. Premium Western botulinum toxin and filler brands cost more per unit than Korean alternatives; a male jawline often needs more product than a typical female case.
Anaesthesia type. Local anaesthesia is cheaper than sedation or general anaesthesia.
Package inclusions. Hospital nights, garments, medications, lab work, and follow-ups can be bundled or extra. For medical travellers, factor in flights, accommodation, and time off work too.
Who is a good candidate, and who is not
Good candidates for jawline contouring generally share a few things: a specific, nameable concern (a recessed chin, a heavy masseter, fat under the chin, a flat jaw angle), realistic expectations about how much change is achievable, reasonable general health, and, for surgery, no active gum disease or dental infection given how often these incisions are placed inside the mouth.
The right procedure depends entirely on which problem you actually have, which is why a clinician will often examine, photograph, and sometimes scan before recommending anything. Two men who both say "I want a better jawline" can leave with completely different plans.
Who it is not for, and contraindications
Men seeking a fundamental change to their face shape that no single procedure can deliver, or who are influenced by heavily filtered images. Body dysmorphic concerns are a genuine reason to pause rather than proceed.
Men with significant skin laxity who actually need a neck lift, not liposuction or filler.
For masseter Botox: known hypersensitivity to botulinum toxin, certain neuromuscular disorders (such as myasthenia gravis), and pregnancy or breastfeeding. Long-term, repeated masseter Botox has been linked to reduced bone density at the jaw angle in some reports, a theoretical concern that may matter more for older or post-menopausal patients (Popescu et al., 2024).
For fillers: active skin infection at the site, a history of severe allergic reactions, and caution in anyone on blood thinners.
For surgery: uncontrolled diabetes or hypertension, bleeding disorders, active infection, smoking (which impairs healing), and unrealistic expectations. Active dental or gum infection should be treated first when an intraoral approach is planned.
This list is not exhaustive, and only an in-person assessment can clear you for a specific procedure. Treat any clinic that skips the medical history as a red flag in itself.
What the procedures involve, step by step
Injectables (Botox or filler) are straightforward office visits. The area is cleaned, sometimes numbed with topical cream or local anaesthetic, and the product is injected through fine needles or a blunt cannula. The visit usually takes 15-30 minutes, and most men return to normal activity the same day, avoiding heavy exercise, alcohol, and (for filler) pressure on the area for a day or two.
Surgical contouring follows a more involved path:
Assessment and planning. Photographs, examination, and sometimes a CT scan or 3D imaging to plan implant size or bone movement.
Anaesthesia. Local with sedation for smaller cases, or general anaesthesia for jaw angle implants and genioplasty.
Incisions. Usually hidden inside the mouth, or via a small cut under the chin for submental liposuction.
The core procedure. Placing and securing the implant, or cutting and advancing the chin bone and fixing it with a small plate and screws, or suctioning the submental fat.
Closure and dressing. Sutures, and often a supportive chin or compression garment.
Total theatre time is commonly 1-3 hours depending on how many areas are addressed in one session.
Recovery, staged honestly
Injectable recovery is minimal. After filler, expect possible swelling, tenderness, and bruising for a few days; the result is visible immediately and settles over one to two weeks. After masseter Botox, there is little to no downtime, but the slimming effect builds gradually over four to twelve weeks, so do not judge it in the first fortnight.
Surgical recovery runs in stages, and individuals vary:
Days 1-3: Swelling, tightness, and bruising peak. Discomfort is usually manageable with prescribed medication. If incisions are inside the mouth, a soft diet and careful oral hygiene matter.
Week 1: Many men return to desk-based work, often still visibly swollen. Sutures inside the mouth may dissolve; external ones come out around now.
Weeks 2-3: Swelling drops noticeably and the new contour starts to read.
Weeks 4-6: Most everyday activity and exercise resume, depending on the surgeon's clearance.
Months 3-6: Residual swelling resolves and the final, settled shape becomes clear. Numbness around the chin or lip, if present, usually recovers over this window but can occasionally take longer.
Follow your surgeon's specific aftercare instructions over any generic timeline, since the plan depends on exactly what was done.

Results: how much change, and how long it lasts
Outcomes are best described by technique rather than as a single promise.
Masseter Botox: a measurable reduction in lower-face width, around a tenth at peak in published work, building over weeks and lasting roughly four to six months early on, often longer as treatments are repeated (Klein et al., 2014).
Chin and jawline filler: immediate added projection and definition, with a mean duration near 13 months and high reported satisfaction, after which top-ups maintain the look (Al-Khafaji et al., 2023).
Chin implant or genioplasty: a permanent change in chin projection, with high long-term satisfaction in the literature and predictable soft-tissue translation, particularly for genioplasty (Kauke-Navarro et al., 2025).
Submental liposuction: a lasting improvement in the jaw-neck line, since removed fat cells do not return, provided weight stays stable and skin tone is good.
Photographs of your own pre- and post-treatment profile, taken under consistent lighting, are the fairest way to judge a result, and a clinic should be willing to take and share them.
Risks and side effects
Every procedure here carries risk, and a clinic that implies otherwise is not being straight with you.
Common, usually temporary effects. Swelling, bruising, tenderness, and short-lived asymmetry are normal after injectables and surgery alike. Masseter Botox can occasionally cause a temporary change in smile or chewing fatigue, and paradoxical bulging of the muscle if the toxin is placed unevenly (Popescu et al., 2024). Filler can cause lumps or nodules, most of which settle or can be dissolved.
Less common but more serious. Implants can become infected, shift, or look asymmetric and may need revision or removal. Surgery can injure the nerves supplying sensation to the lip and chin, causing numbness that is usually temporary but occasionally persistent. The most feared filler complication is vascular occlusion, where filler blocks or compresses a blood vessel; in the chin and jaw this is rare but can threaten the overlying skin and, very rarely, vision, which is exactly why injector skill and anatomy knowledge are not optional.
Red flags: seek urgent medical care. Contact your clinic or go to an emergency department promptly if you notice any of the following after a procedure:
Sudden, severe, or worsening pain out of proportion to what was expected
Skin that turns white, dusky, mottled, or blue-black, especially after filler (possible vascular occlusion)
Any change in vision after filler
Spreading redness, heat, swelling, fever, or pus (possible infection)
Difficulty breathing or swallowing, or a widespread rash (possible allergic reaction)
Prompt treatment of a vascular occlusion or infection dramatically changes the outcome, so do not wait to "see if it settles."
How to choose a safe clinic, and the red flags
Because much of this work is irreversible and some of it is genuinely high-skill, clinic and surgeon selection is the most important decision you will make, more than the price.
What to look for:
A licensed, appropriately specialized doctor. For surgery, a board-certified plastic or facial surgeon who performs jaw and chin contouring regularly, ideally with experience in male faces. For injectables, a doctor or trained medical injector, not a non-medical "technician."
Accreditation and a real facility. Recognized hospital or clinic accreditation (such as JCI or AACI for hospitals), a proper operating environment for surgery, and clear emergency protocols.
A genuine consultation. A clinician who examines you, takes a medical history, discusses what suits your anatomy, and is honest about limitations, rather than upselling a fixed package.
Transparent, itemized pricing. A written quote that spells out what is and is not included.
Real before-and-after photos of male patients and a willingness to discuss complications and revision policy.
Red flags worth walking away from:
Pressure to decide immediately, "today only" discounts, or deposits demanded before any assessment
No medical history taken, or prescription treatments offered without a consultation
Prices that seem far below everything else (often a sign of unlicensed product or an inexperienced injector)
Reluctance to name the surgeon, the implant brand, or the anaesthesia plan
Treatment offered purely online with no in-person examination before a procedure

Booking a consultation
If you are weighing up jawline contouring, the most useful next step is a proper assessment rather than committing to a procedure from a price list. A consultation lets a clinician examine your face, identify whether the issue is bone, muscle, fat, or a mix, talk through which approach genuinely suits you, and give you an itemized quote with realistic expectations. Because every treatment here is a medical procedure, and the prescription ones require a prescription, an in-person evaluation is not just advisable, it is required before treatment.
Book a jawline contouring consultation at Menscape Bangkok to discuss your options discreetly with a clinician who works specifically with men's faces. You can also read more about related procedures in our guides to male facelift surgery and liposuction for men.
Frequently Asked Questions
Is jawline contouring for men surgical or non-surgical?
Both options exist. Non-surgical contouring uses masseter botulinum toxin to slim or balance a heavy jaw muscle and dermal fillers to add structure to the chin and jaw angle; these are temporary or reversible with little downtime. Surgical contouring uses chin or jaw angle implants, sliding genioplasty, or submental liposuction for permanent change. Which is right depends on whether your concern is bone, muscle, or fat, which a consultation determines.
How much does jawline contouring for men cost in Bangkok?
As an indicative range in early 2026, masseter Botox runs about 8,000-25,000 THB, jawline or chin fillers about 12,000-75,000 THB, submental liposuction about 40,000-90,000 THB, chin implants about 40,000-110,000 THB, sliding genioplasty about 90,000-150,000 THB, and jaw angle implants about 75,000-180,000 THB. These are typically 60-80% cheaper than comparable work in the US, UK, or Australia. Final pricing depends on the surgeon, clinic, implant, anaesthesia, and what the package includes, so confirm at consultation.
How does masseter Botox change the jawline, and how long does it last?
Botulinum toxin injected into the masseter chewing muscle reduces its activity, so over weeks the muscle thins and the lower face looks less wide or boxy. Published work shows the reduction peaks around 12 weeks at roughly a tenth of lower-face width. Early on it lasts about four to six months, and the interval often lengthens with repeated treatments. In men, injectors usually aim to balance or refine rather than maximally slim, to avoid feminizing a face that suits a squarer shape.
Is a chin implant or a sliding genioplasty better for a weak chin?
Both work well and satisfaction is high with each. An implant is simpler, faster, and removable, and suits modest, straightforward projection. A sliding genioplasty moves your own chin bone and handles larger or more complex corrections, with slightly more predictable soft-tissue change and lower infection and revision rates in pooled data. Implants carry a somewhat higher infection and reoperation rate. The right choice depends on how much movement you need and your risk preferences, decided at consultation.
How long is the recovery after surgical jawline contouring?
Swelling and bruising peak in the first three days. Many men return to desk work within a week, still somewhat swollen. Swelling drops noticeably by weeks two to three, most exercise resumes around weeks four to six with surgeon clearance, and the final settled shape appears over three to six months. Numbness around the chin or lip, if it occurs, usually recovers within that window. Injectable treatments have minimal downtime by comparison.
What are the main risks of jawline contouring?
Common, usually temporary effects include swelling, bruising, tenderness, and short-lived asymmetry. Masseter Botox can occasionally cause a temporary smile change or muscle bulging. Implants can become infected, shift, or look asymmetric and may need revision. Surgery can cause temporary or, rarely, lasting numbness of the lip and chin. The most serious filler complication is vascular occlusion, which is rare but can threaten skin or, very rarely, vision. Seek urgent care for severe pain, skin that turns pale or dusky, any vision change, spreading redness or fever, or breathing difficulty.
Will jawline contouring make my face look feminine?
It should not, if it is planned with male anatomy in mind. The male jaw is typically wider at the angle with a sharper, less obtuse jaw angle and a taller, more projected chin, and techniques designed to narrow or taper a face can feminize a man's lower third if applied without that in mind. A clinician experienced with men's faces aims for a squarer, more defined result and uses restraint with jaw-slimming injections, so choosing an injector or surgeon who regularly treats male patients is important.
Am I a good candidate for jawline contouring?
Good candidates have a specific, identifiable concern such as a recessed chin, a heavy masseter, fat under the chin, or a flat jaw angle, along with realistic expectations and reasonable general health. For surgery using incisions inside the mouth, healthy gums with no active dental infection matter. It is less suitable for men with significant skin laxity who need a neck lift, those with body dysmorphic concerns, and anyone with relevant contraindications such as bleeding disorders or, for Botox, certain neuromuscular conditions. Only an in-person assessment can confirm suitability.
Do I need a consultation and prescription before treatment?
Yes. Every treatment described here is a medical procedure, and the prescription-only ones, including botulinum toxin, dermal fillers, and all surgery, legally require an in-person assessment and, where relevant, a prescription from a licensed doctor. A consultation also lets the clinician examine your face, work out whether your concern is bone, muscle, or fat, and recommend the option that genuinely suits you rather than a fixed package.
