When you look in the mirror, you may wonder whether your jawline could appear more defined, more sculpted, more in harmony with the rest of your face. The good news is that you don’t always need surgery to achieve that kind of transformation. 

At The Refinery Medspa & Wellness, we are proud to offer a solution that is minimally invasive, quick, and tailored to your unique facial structure. 

Understanding the V‑Shaped Jawline and Why It Matters

A strong, gently contoured jawline has become a hallmark of modern facial aesthetics. It conveys youth, structure and balance. But as we age, or if we carry tension in our jaw muscles, that crisp line can begin to soften. The angle between your jaw and neck might round off, the lower face may appear heavier, and you may feel the outline of your face is less defined.

Having a well‑defined lower third of the face can boost confidence and harmonize your features. The focus here is not on over‑enhancement or looking artificial – it’s about subtle structure, natural elegance and balance.

Facial slimming via injectables offers a non‑surgical option that interrupts two key influences on jawline definition: the size or strength of the masseter muscles (chewing muscles on each side of the jaw) and the distribution of fat or soft tissue in the lower face. By carefully targeting those areas with a neurotoxin like Botox or similar agents we can soften the bulk of the muscle or reduce its contribution to the jaw width, thereby narrowing the lower face, lifting the angle, and letting that V‑shape emerge.

What Exactly Happens During a Facial‑Slimming Neurotoxin Treatment

At The Refinery Medspa our injectors are highly trained in facial anatomy and the ‘injectable signature’ of the lower face. 

The process looks like this:

1. Consultation & Assessment

We begin with a complementary consultation at our West Melbourne location or Beachside clinic in Indian Harbour Beach. During this time we assess your jawline, your masseter muscles (you may clench or grind your teeth, causing bulkiness), the skin tone, the fat pad under the chin or along the jawline, and your aesthetic goals. We review your medical history and any previous treatments. 

2. Mapping and Planning

Once we’ve established that you’re a suitable candidate, we mark the areas for injection. For facial slimming via neurotoxin we often treat the masseter muscles (the thick muscles at the back of the jawline) to reduce their size over time and thus narrow the lower face. We may also treat other dynamic jawline‑muscles or support with contouring fillers if needed (in which case we’ll discuss that as part of your plan).

3. Injection

The neurotoxin is injected in small, precise amounts directly into the masseter muscles on both sides. The process typically takes 15 – 30 minutes and requires no general anaesthesia or downtime. Most clients read, relax, talk, or even use their phones during the appointment.

4. Initial Effects & Gradual Change

Within a few days you’ll begin to feel less tension in the jaw (particularly if you grind or clench your teeth), and over the next 4 to 8 weeks you’ll notice a gradual narrowing of the lower face and more definition in the jawline. Full results typically appear by 8‑12 weeks, and the effect continues to mature over 3‑4 months.

5. Maintenance & Follow‑Up

The effects of neurotoxin in the masseter last about 4 to 6 months for most patients, but this depends on your metabolism, muscle usage (clenching, chewing), and lifestyle. 

Why Choose The Refinery Medspa for Your Jawline Refinement

At The Refinery Medspa & Wellness we believe your facial structure deserves as much care as your skin. 

Here are some reasons clients trust us with facial‑slimming treatments:

• Expert injectors who focus on facial anatomy, jawline musculature and lower‑face aesthetics.
• Tailored approach — each treatment is customized to your face rather than a one‑size‑fits‑all protocol.
• Complimentary consultations so you understand your goals and options before any procedure.
• Minimal downtime — most facial‑slimming injections allow you to resume normal activities almost immediately.
• Full scope of services — if you want additional contouring or volume correction we integrate treatments like fillers (e.g., Juvederm Ultra XC), lasers or RF microneedling in our West Melbourne or Indian Harbour Beach clinics.
• Holistic care — beyond aesthetics we support wellness, skin health, and longevity of results.

Who Is a Good Candidate for Facial Slimming with Neurotoxin?

You may be an excellent candidate if you match several of these characteristics:

• You notice a broad jawline that is influenced by muscle bulk (particularly the masseter) or you clench/grind your teeth.
• You feel your jawline lacks definition, your lower face appears heavier or your chin‑to‑jaw angle is softened.
• You would prefer a non‑surgical option to refine your lower face.
• You have realistic expectations and are willing to commit to a maintenance schedule.
• You are in general good health, not pregnant or breastfeeding, and understand the risks of injectable treatments.
• You are working with a licensed professional in a medical spa setting like The Refinery.

That said, facial‑slimming treatments are not for everyone. If you have very lax skin, heavy fat deposits under the chin, or skeletal irregularities, we may recommend complementary treatments (like ultrasound tightening or Kybella® fat‑dissolving injections) rather than relying solely on neurotoxin. 

During your consultation we’ll guide you to the best plan.

What to Expect During and After the Procedure

Your comfort and safety are our top priority. Here is what you should expect:

Before the treatment

• When you arrive at our clinic, we review the plan one more time, cleanse the skin, and may apply topical numbing if requested (though most patients feel minimal discomfort).
• We mark the injection sites and explain what you might feel (a quick pinch or sting).
• Please avoid strenuous chewing or jaw clenching for a few hours before and after your appointment to minimize muscle activation.

During the treatment

• You’ll recline in a comfortable treatment chair.
• The injector administers small injections into the marked masseter muscle areas on both sides.
• The process takes about 15‑30 minutes depending on the scope of treatment.

After the treatment

• You may resume most activities immediately. We recommend avoiding vigorous jaw‑use (chewing gum, heavy chewing) and intense massage of the area for 24 hours.
• Some clients experience mild swelling or tenderness at the injection sites for a day or two, this resolves quickly.
• You should begin to see results within a week, but more subtle structural changes continue over 4‑8 weeks.
• As your jawline gradually narrows and the angle becomes sharper, people around you may comment on your refreshed look, even if you don’t mention the treatment.

How to Maintain Your Defined Jawline for the Long Term

Permanent changes rarely happen after only one visit. At The Refinery we work with you on maintenance to keep your results consistent and sustainable:

• Follow‑up appointments approximately every 4 to 6 months, depending on how your body metabolizes the neurotoxin and how much jaw‑muscle activity you employ.
• Lifestyle support – reduce nighttime teeth clenching, limit heavy chewing, avoid excessive gum chewing or bruxism. If needed, we can co‑treat with oral appliances for bruxism or recommend stress‑management techniques.
• Complementary treatments – in some cases, adding facial fillers along the jawline or chin, skin tightening with RF microneedling or laser‑assisted contouring helps maintain the sculpted look.
• Sun protection and skincare – maintaining skin quality matters. At The Refinery we support you with skincare products and treatments so that your refined structure is showcased with clear, healthy skin.
• Healthy habits – overall wellness, hydration, good posture and neck/shoulder muscle tone all contribute to how clean your jawline looks.

Before‑and‑After Expectations: What Results Look Like

When done thoughtfully, the outcome is natural, elegant and reflects your own facial architecture rather than looking “overdone”. Here is what you might realistically expect:

• A subtly narrower lower face, particularly when viewed frontally.
• A more pronounced jaw angle as the transition from the ear to the jawline becomes sharper and clearer.
• Less prominence of the masseter muscle when you clench or chew, resulting in a smoother lower‑face silhouette.
• A lifted feel to the lower face and neck region because the tension in the masseter is reduced and the supporting musculature can respond differently.
• Enhanced results when combined with good skin tone and healthy lifestyle, which is why our holistic med‑spa approach matters.

Safety, Risks and Things to Ask During Your Consultation

At The Refinery Medspa we maintain high safety standards. Neurotoxin treatments for facial slimming are generally safe when administered by experienced professionals, but like all medical aesthetic procedures they carry some risks and considerations:

• Temporary jaw‑weakness: Because we are reducing muscle activity, some patients feel less chewing strength for a week or two, this is normal and resolves.
• Smile or bite changes: Rarely the nearby muscles respond differently and you may notice altered chewing or smile temporarily.
• Bruising or swelling: Mild bruising at the injection site is possible; we take steps to minimize it.
• Infection: Very rare but as with any injection there is minor risk,  we follow strict sterile protocols.
• Unrealistic expectations: If you expect drastic surgical‑level changes, you may be disappointed. That is why our consultation sets realistic goals.

Questions to ask during your consultation:

• How many units of neurotoxin will be used for the masseter?
• How many prior cases of facial‑slimming have you done?
• What is the expected timeline for my results and what is the maintenance plan?
• Will I need additional treatments to achieve optimal definition (fillers, skin tightening)?
• What is the cost‑structure and is there any downtime I should plan for?

Why Clients Choose Non‑Surgical Over Surgical Options for Jawline Refinement

Surgical jawline contouring, chin implants or lower‑face lifts are valid options but they come with higher cost, longer downtime and increased risk. 

Non‑surgical facial‑slimming with neurotoxin offers multiple advantages:

• Minimal downtime – you can often resume daily activities immediately.
• Lower cost compared to surgical alternatives.
• Lower risk of major complications.
• Ability to fine‑tune results over time rather than committing to one irreversible change.
• Works especially well when combined with lifestyle changes and skincare support.
