Jaw Slimming with Botox at Rappoel Clinic
Rappoel Dermatology · Masseter Reduction · Natural V-Line Contour
A wide or square jawline is one of the most common facial concerns. Botulinum toxin (Botox) masseter injection is currently one of the safest and most effective non-surgical methods for face-slimming. At Rappoel Dermatology, jaw-slimming injection is the most frequently requested treatment.
Rappoel physicians have extensive clinical experience with Botox injections. Prior to treatment, masseter thickness is precisely assessed through palpation to create a personalized dosage plan — naturally reducing face width while preserving normal chewing function.
How Does Masseter Botox Slim the Face?
Botulinum toxin injected into the masseter muscle blocks nerve-to-muscle signals, causing the muscle to gradually atrophy and reduce in volume. This decreases lower face width, transforming a square or trapezoidal face shape into a more oval, V-line contour.
💡 Effects gradually appear over 2–4 weeks post-injection, with optimal results visible at 3 months — natural and subtle.
Who Is It For?
• Heavy chewers with prominent masseter muscles
• Square, wide, or rectangular face shape
• Teeth grinders (bruxism)
• Jaw tension causing headaches
• Those seeking face-slimming without surgery
Procedure & Recovery
Topical anesthetic is applied beforehand. The entire procedure takes under 15 minutes with no downtime — you can apply makeup and work on the same day. Avoid hard foods for 2 weeks post-injection.
How Long Do Results Last?
Results typically last 4–6 months. With regular injections, the masseter continues to reduce over time. A maintenance injection every 6 months is recommended for long-term improvement.
Frequently Asked Questions
Q：Will my face look asymmetrical after injection?
A：Rappoel physicians carefully assess both masseters before treatment and adjust dosing for any asymmetry, ensuring balanced, natural results.
Q：Can I still chew normally after masseter reduction?
A：Yes. The chewing function is fully preserved — only the muscle volume decreases, with no impact on daily eating.
Q：Is Botox safe?
A：Medical-grade botulinum toxin has decades of clinical use with an established safety profile. Rappoel uses only certified imported products.
Q：Will I see results after the first injection?
A：Most patients see significant improvement 2–3 months after the first session. Results become more pronounced and longer-lasting with repeated treatments.
Q：When can I resume normal activities?
A：No downtime. You can return to work and social activities the same day, with the only restriction being to avoid lying down for 4 hours post-injection.
Q：How is Botox different from jaw surgery?
A：Botox is non-invasive, reversible, and risk-free compared to surgery. Surgery offers more permanent bone reshaping but involves significantly higher risks and recovery time.
