Masseter Botox in Bangkok — Jaw Slimming Cost & What to Expect (2026)
Masseter botox — injecting botulinum toxin into the jaw muscle — is the fastest-growing aesthetic treatment among Korean and international visitors in Bangkok. It slims the lower face, softens a square jaw, and requires zero downtime. Bangkok clinics perform thousands of these per month at 40–60% of Singapore or Seoul prices.

What masseter botox costs in Bangkok
Price depends on dosage (units) and brand. Typical: ฿3,500–5,000 for 25 units/side (Botulax, Dysport); ฿5,500–8,000 for genuine Allergan at the same dose. Most clinics charge per unit (฿80–250/unit) rather than per area. Maintenance sessions: the muscle gradually returns; most patients retreat every 4–6 months. Many Bangkok clinics offer a 3-session package at 15–20% discount. Budget alert: prices under ฿2,500 typically indicate heavily diluted product or unverified brand — ask to see the vial.
Units needed and dosage guide
25–35 units per side is standard for first-time masseter reduction. Patients with very strong hypertrophic masseter muscles (teeth-grinders, heavy jaw clenchers) may need 40–50 units/side for visible results. V-line candidates: 30 units/side is the most common Bangkok protocol. Results visible at 4–6 weeks as muscle atrophies; full effect at 8–12 weeks. Don't judge result at 2 weeks — many patients return too early and top up unnecessarily. Trust the timeline.
How to pick a Bangkok masseter specialist
Look for a clinic where the injector regularly treats Korean and Japanese clients — they have the highest volume and strictest aesthetic standards for V-line results. Reviewers mentioning 'natural V-line', 'not overdone', or '사각턱' (Korean: square jaw) are strong signals of a specialised injector. Avoid clinics where the treatment takes under 10 minutes for a first-time patient — proper assessment of your masseter size should take at least 5–10 minutes. Trust Score 70+ on this site indicates clinics with strong reviewer credibility.
Frequently asked
How much is masseter botox in Bangkok?⌄
฿3,500–8,000 for a standard treatment (25–35 units/side). Allergan/Botox-original at the premium end; Botulax/Dysport at the value end. Both produce comparable jaw-slimming results at correct dosage.
How many sessions before I see jaw slimming results?⌄
One session is enough for most patients. Results are visible at 4–6 weeks, full effect at 8–12 weeks. The jaw muscle physically atrophies (shrinks) — this takes time. Most patients retreat every 4–6 months to maintain the effect.
Is masseter botox safe?⌄
Yes, at qualified clinics. The masseter is a non-critical muscle — reducing it doesn't affect chewing for most patients (some notice minor change with very chewy foods in the first month). Serious complications are rare and reversible since botox wears off.
Can I combine masseter botox with filler on the same day?⌄
Yes — many Bangkok clinics do botox + chin filler on the same visit for a complete V-line effect. The combination is well-tolerated. Some practitioners prefer to assess the botox result first (at 8 weeks) before adding chin projection.
