About This Treatment

BTX Singapore — Two Categories of Treatment

BTX treatment in Singapore addresses two distinct clinical categories. The first is wrinkle prevention and reduction — relaxing facial muscles responsible for dynamic lines and treating the DAO (depressor anguli oris) and platysmal bands of the neck. The second is face and body contouring — using BTX to slim and reshape through targeted muscle volume reduction.

Dr Sin Yong selects a formulation chosen for its predictable diffusion profile and rapid onset for most zones. For frown lines (glabellar 11 lines), a typical dose is 16–20 units, calibrated to each patient's muscle mass and expression pattern. Alternative formulations are used in specific zones where a more localised action profile is preferred.

BTX is far more effective as a preventive tool than a corrective one. Starting BTX treatment at the point where dynamic lines first appear — typically the late 20s — prevents them from ever becoming static, deep folds requiring filler. Results are natural-looking, preserving expression while eliminating unwanted muscle activity.

BTX Treatment — Two Categories

Category 1

Wrinkle Prevention & Reduction

01
Frown Lines (Glabellar 11 Lines)
The glabellar complex is the most impactful and commonly treated BTX zone. Dr Sin Yong's typical dose for frown lines is 16–20 units — targeting the corrugator supercilii and procerus muscles. Precise placement preserves brow position while eliminating the 11 lines between the brows.
02
Forehead Lines
Horizontal forehead lines from frontalis activity. Dosing must be carefully calibrated — the frontalis is the sole brow elevator, so overtreating drops the brow and creates a heavy, tired appearance. Dr Sin Yong preserves appropriate frontalis tone while softening the visible lines.
03
Crow's Feet
Lateral periorbital lines from orbicularis oculi activity. One of the most visible treatment zones with excellent patient satisfaction. Treatment preserves natural eye squinting movement while softening the radiating lines at the outer eye corners.
04
DAO & Platysmal Bands — Lower Face & Neck
The depressor anguli oris (DAO) pulls the oral commissures downward, creating a permanently sad or stern expression. BTX into the DAO relaxes this downward pull — lifting the corner of the mouth and softening the marionette line region. Platysmal bands are prominent vertical neck cords that emerge with age — BTX into the platysma relaxes these bands and softens horizontal neck lines, producing the Nefertiti lift effect.
Category 2

Face & Body Contouring with BTX Singapore

05
Jaw Slimming — Masseter BTX Singapore
Masseter BTX Singapore is one of the most transformative non-surgical treatments for lower face slimming. BTX injected into the masseter causes progressive muscle atrophy over 4–6 weeks — reducing jaw width and creating a slimmer, more tapered lower face. Results last 4–6 months and improve with repeated treatment as the muscle responds to sustained reduction. This treatment also reduces bruxism (teeth grinding) and associated TMJ jaw pain.
06
Trapezius Slimming — Barbie BTX Singapore
BTX into the trapezius muscle reduces the bulk of the upper shoulder muscle — creating a more feminine, elongated neck-to-shoulder transition. Commonly referred to as "Barbie BTX," trapezius BTX treatment in Singapore is increasingly sought after for both aesthetic shoulder slimming and relief from trapezius-related tension headaches and neck stiffness. Results last 3–5 months.
07
Calf Slimming BTX Singapore
BTX injected into the gastrocnemius muscles of the calf reduces muscle bulk — slimming the calf silhouette and improving the leg contour from behind. Calf slimming BTX in Singapore produces a visible reduction in calf girth over 4–6 weeks as the muscle fibres reduce in mass. This is particularly effective for patients with hypertrophic calf muscles from athletic activity. Results last 4–6 months.

Frequently Asked Questions

3–5 months depending on the product, dose and individual metabolism. Regular treatment every 4 months maintains the preventive effect — preventing lines from deepening between sessions.
Different BTX formulations vary in diffusion profile, onset time and dosing. Dr Sin Yong selects the formulation most appropriate for each zone and patient.
When dynamic lines are first visible at rest — typically mid-to-late 20s for expressive faces. Starting earlier prevents lines from ever becoming static folds that require filler to correct.
Only with excessive doses. Dr Sin Yong calibrates BTX to relax the target muscle while preserving natural expression — the 'frozen' look is always a sign of overdosing, not of the treatment itself.
Masseter BTX reduces jaw muscle bulk progressively over 4–6 weeks — slimming the lower face width. Results last 4–6 months and require maintenance to sustain.
BTX has been used clinically for over 30 years with an excellent long-term safety record. There is no evidence of permanent structural change from appropriate long-term use.

BTX Singapore — Full Treatment Areas

Forehead lines — Relaxes frontalis muscle. Dose carefully calibrated to avoid brow ptosis from over-treatment.

Frown lines (glabellar 11 lines) — A common BTX application, working through corrugator and procerus relaxation.

Crow's feet — Softens periorbital lines while preserving natural eye expressiveness. Technique matters — incorrect placement risks lower lid ectropion.

Jaw slimming (masseter BTX) — Reduces masseter bulk over 4–8 weeks, creating a slimmer V-shaped lower face. Also treats bruxism and TMJ pain.

Lip lines — Micro-doses relax perioral lines without affecting lip function. Precision dosing is critical.

Neck bands (platysmal bands) — Relaxes prominent vertical neck cords, improving neck contour and reducing vertical neck lines.

Preventive BTX — Dr Sin Yong recommends preventive treatment from the late 20s before dynamic lines become static. Lower doses last longer in patients without established wrinkles.

Key facts
Approach
BTX, a muscle-relaxing injectable technique
Mechanism
Blocks acetylcholine release at the neuromuscular junction, reducing the muscle contraction that creates dynamic lines
Units not interchangeable
Potency units are specific to each formulation's own assay and cannot be converted between different formulations
Reconstitution
Preservative-free 0.9% sodium chloride; used within one session, refrigerated 2–8 °C, discarded after 24 hours
Directed at
Dynamic lines produced by muscle movement, not static lines from volume loss or skin quality

“Units of biological activity are specific to each formulation and its own assay method. A number quoted for one formulation cannot be compared to or converted into units of another.”

BTX vs Fillers — Understanding the Difference

BTX treats the CAUSE of dynamic wrinkles by relaxing the underlying muscle. It does not add volume and is not appropriate for static lines present at rest.

Fillers treat the EFFECT of volume loss and static lines by adding material to the deflated or creased area. They do not affect muscle activity.

The two are complementary, not interchangeable. A common mistake is using filler to treat dynamic forehead lines (where BTX is appropriate) or BTX to treat tear troughs (where filler is appropriate). Dr Sin Yong assesses each concern individually to recommend the correct treatment.

For frown lines (glabellar 11 lines), a typical dose is 16–20 units — calibrated to the individual patient's corrugator and procerus muscle mass and expression strength. The formulation used is selected for its predictable diffusion profile and rapid onset.
Yes — BTX Singapore treatments for body contouring include: masseter jaw slimming (smaller lower face), trapezius slimming for a more feminine shoulder line, and calf slimming BTX for leg contouring. All work by causing progressive muscle volume reduction over 4–6 weeks at the injection site. Results last 3–6 months depending on the muscle treated.
BTX price in Singapore varies by treatment zone, units required and formulation. Formulation is selected per patient and zone — priced per unit with the total depending on the area treated.

Trapezius BTX (also called "Barbie BTX") involves injecting BTX into the trapezius muscle of the upper back/shoulder. This reduces the muscle bulk progressively — creating a more feminine, sloped shoulder-to-neck transition and visually elongating the neck. It also relieves trapezius-related tension headaches and chronic neck stiffness. Trapezius BTX Singapore treatment lasts 3–5 months.
