Face slimming isn’t a single procedure. It’s a tailored plan that treats the root cause of a wide or round lower face: bulky masseter muscle, submental/cheek fat, skin laxity and/or a short/recessed chin.

Below you’ll find clear comparisons, transparent device treatment prices, and answers to the 10 most-asked (and least-asked) questions—so you can choose with confidence.

Answer at a glance

Strong jaw muscle → Masseter botulinum toxin (slimming in 2–4 wks; lasts 4–6 mos).
Skin laxity/jowls → HIFU (or Sygmalift if you’re pain-sensitive) for lift/definition.
Short chin → Chin filler for instant projection and a balanced V-line.
Double chin fat → HIFU submental or Fat Freeze; results evolve 4–12 wks.
Best outcomes often combine 2–3 modalities for a natural, long-lasting V-shape.

What makes a face look slimmer (or wider)?

Cause → Treatment

Bulky masseter muscle (boxy jaw when clenching) → Masseter botulinum toxin
Submental/cheek fat (double chin/fullness) → HIFU or Fat Freeze (Cool Shaping 2)
Skin laxity (soft jawline/jowls) → HIFU or Sygmalift
Short/recessed chin (weak profile) → Chin filler (HA)

Tip: Take a selfie while gently clenching. If the jaw corners bulge, you likely have masseter hypertrophy (muscle-led width). If the profile looks soft under the chin, target fat + laxity first.

Face Slimming Overview

Primary cause	How it looks	First-line option(s)	What it does	Timeline
Strong/bulky masseter	Boxy lower face when clenching	Masseter botulinum toxin	Relaxes & slims chewing muscle	Change 2–4 wks; peak 4–6 wks; lasts 4–6 mos
Submental/cheek fat	Double chin; soft fullness	HIFU (submental) / Fat Freeze	Heat or cooling to reduce fat; some tightening	Gradual 4–12 wks
Skin laxity/jowls	Soft jawline, early jowls	HIFU / Sygmalift	Collagen remodeling & lifting	Peak 2–3 mos

Face Slimming Treatment Options (how they work, downtime and suitability)

Masseter Botulinum Toxin (Jaw Slimming)

Masseter botulinum toxin works by relaxing the overactive chewing muscles on both sides of the jaw.

When the muscle no longer contracts as strongly, it gradually reduces in size, creating a slimmer and softer lower-face contour.

This non-surgical method is ideal for people with a square or broad jawline caused by muscle bulk rather than fat. It also has the added benefit of easing jaw clenching, teeth grinding and face slimming effects for some patients.

Mechanism: precise units into the masseter to slim muscle bulk and soften a square jaw. Also helps bruxism.

When you’ll see it: changes at 2–4 weeks, peak at ~4–6 weeks; repeat 4–6 months.

Units: commonly ~20–30 units/side (F), 30–50/side (M)—final dose is individualized.

Downtime & feel: minimal; brief pinches; transient chewing fatigue is possible.

Good pairings: HIFU for skin; chin filler for projection if the chin is short.

HIFU (High-Intensity Focused Ultrasound)

HIFU uses focused ultrasound energy to deliver precise heat into the SMAS layer and deeper dermis, the same structural layer tightened in surgical facelifts.

This stimulates collagen contraction and remodeling, tightening loose skin and slightly reducing small fat pockets under the chin or jawline.

The result is a more defined jawline and lifted lower face, with no incisions or downtime. It’s especially useful for mild jowls and early sagging.

What it targets: SMAS (4.5 mm), dermis (1.5–3 mm)—tightens, melts small fat pockets, defines jawline. Device shots are delivered at ~60–70 °C below the skin surface.

Results: some immediate lift; collagen remodeling peaks 2–3 months; maintenance 6–12 months depending on age/skin.

Why patients choose it: non‑invasive, lunchtime procedure, zero downtime. Transparent prices below.

Chin Filler (Hyaluronic Acid)

Chin filler adds projection and balance to the lower face using biocompatible hyaluronic acid gel.

By enhancing the chin’s forward length and vertical height, it improves the facial golden ratio and gives the illusion of a longer, slimmer face.

It’s perfect for individuals whose roundness is due to a short or recessed chin, and results are visible immediately after injection with minimal recovery time.

Use case: short or recessed chin; immediate V‑line improvement and jawline continuity; complements jaw BTX/HIFU.

Longevity: typically 6–12 months; exact duration depends on filler and anatomy.

Price guidance: $980–$1,200 per 1 ml stated on baclinic.sg (final quote after consultation per SG rules).

Fat Freeze (Cryolipolysis / Cool Shaping 2)

Fat Freeze targets stubborn submental or cheek fat by cooling fat cells to a temperature that triggers apoptosis (natural cell death) without harming surrounding tissues.

Over the following weeks, the body naturally clears these damaged fat cells through the lymphatic system, resulting in a more sculpted and refined lower face.

It’s particularly effective for double-chin reduction and pairs well with HIFU or botulinum toxin for complete contouring.

Use case: fuller cheeks or double chin; defines jawline and refines lower-face contour; complements jaw BTX / HIFU.

Longevity: long-lasting; maintenance every 6–12 months depending on lifestyle.

Price guidance: $198 per cup / $238 per session as listed on baclinic.sg (final quote after consult per SG rules).

Side‑by‑side comparison

Treatment	Best for	How it helps	Onset → Peak	Longevity / Maintenance	Downtime	Typical price (BA Clinic)	Notes
Masseter botulinum toxin	Muscle-led width / boxy jaw	Relaxes overactive masseter so the muscle gradually slims → narrower lower face	2–4 wks → 4–6 wks	~4–6 months; repeat as needed	Minimal	Consult for price	Can also ease bruxism; pairs well with HIFU/chin filler
HIFU (jawline / submental)	Skin laxity ± mild fat; soft jawline	Focused ultrasound tightens SMAS/dermis and reduces small fat pockets → sharper jawline	Immediate lift → 2–3 mos	~6–12 months; annual top-up typical	None	From $428 (600 shots); Neck + Double Chin $498	Non-surgical; lunch-time procedure
Chin filler (HA)	Short/recessed chin; weak profile	Adds projection/length to balance proportions → face appears slimmer and V-shaped	Immediate → settles 1–2 wks	~6–12 months (varies by product & anatomy)	Minimal	$980–$1,200 per 1 ml	Complements jaw BTX/HIFU for full contour
Fat Freeze (Cool Shaping 2)	Double chin / lower-face fullness	Controlled cooling triggers fat-cell apoptosis → slimmer, more defined lower face over weeks	4–12 wks (gradual)	Long-lasting; maintain based on goals/lifestyle	Minimal	$198 per cup; Double-chin area $238/session	Pairs well with jaw BTX or HIFU for definition

Which treatment should I start with?

I clench / boxy jaw: Start with masseter botulinum toxin. Add HIFU at 4–6 wks if jawline still lacks definition.
Soft double chin: HIFU submental or Fat Freeze.
Short chin in profile: Chin filler first; layer HIFU or BTX if indicated.
Pain-sensitive: Consider Sygmalift (painless lines) and maintain more frequently.

Frequently Asked Questions (10)

1) What is the best face slimming treatment in Singapore?

Treat the cause: muscle → masseter botulinum toxin; fat → HIFU or Fat Freeze; laxity → HIFU/Sygmalift; short chin → chin filler. Combination plans often look most natural.

2) How long do results last?

Masseter botulinum toxin: 4–6 months; HIFU: 6–12 months; Sygmalift: ~3 months; Chin filler: 6–12 months (varies by product/area and metabolism).

3) Is HIFU painful? What if I’m sensitive?

Most people tolerate HIFU well with brief zaps. If you’re pain-sensitive, Sygmalift offers a comfortable alternative with more frequent maintenance.

4) Will slimming the jaw make me look older or hollow?

When planned correctly, no. We slim muscle/fat while preserving or adding structure (e.g., chin filler) and support (HIFU) to maintain youthfulness.

5) How many sessions will I need?

Masseter botulinum toxin: typically 1 session then 4–6-monthly maintenance. HIFU: usually 1 session then 6–12-monthly maintenance. Sygmalift: sessions every ~3 months. Chin filler: typically 1 session with 6–12-monthly top-ups.

6) Can jaw slimming injections help with teeth grinding?

Yes—relaxing the masseter may reduce clenching/grinding discomfort for some patients.

7) Are there side effects or downtime?

Masseter botulinum toxin: minimal downtime; rare temporary chewing fatigue. HIFU/Sygmalift: no downtime; mild tingles. Chin filler: temporary swelling 24–48 h. Fat Freeze: temporary numbness/tugging; results unfold over weeks.

8) Who isn’t suitable?

Pregnancy/breastfeeding, active skin infections, uncontrolled medical issues, or unrealistic expectations. Your doctor will review your history and examine suitability.

9) How soon before a photoshoot/wedding should I start?

For masseter botulinum toxin, start 6–8 weeks prior (peak at 4–6 wks). For HIFU/Sygmalift, start 8–12 weeks prior. Filler can be closer to the date but allow 2 weeks to settle.

10) How do I choose the right clinic?

Look for experienced doctors, clear explanation of cause → treatment, transparent device pricing, realistic timelines, and a follow-up plan. Check that the clinic provides multiple modalities—so you’re not “fit” into one tool.
