A tight, slim jawline is often associated with a youthful and feminine appearance. At Xavier Clinics we offer a jawline treatment with botulinum toxin It's being promoted as an effective and nonsurgical way to refine a wide or tight jawline. This treatment is particularly suitable for overactive jaw muscles (masseter hypertrophy) and can offer both aesthetic and functional benefits.
What is a botulinum toxin jawline treatment?
This treatment involves botulinum toxin Injected into the masseter muscles (chewing muscles). These muscles can be overly developed due to genetic predisposition, stress, or teeth grinding (bruxism), which can cause an angular or wide jawline. Botulinum toxin relaxes the muscle, causing it to gradually decrease in volume in the weeks following the treatment, giving the jawline a subtly slimmer appearance.
Who is this treatment suitable for?
A jawline treatment with botulinum toxin is suitable for:
- People with a broad or angular jawline due to strongly developed chewing muscles
- Complaints of teeth grinding or jaw clenching
- Tension headache or pain in the jaw region
- Patients who want a slimmer and softer facial contour without fillers or surgery
During the consultation at Xavier Clinics we always carefully assess whether this treatment suits your facial anatomy and personal wishes.
The result
The effect of botulinum toxin in the jaw develops gradually:
- First effect after 7–14 days
- Optimal results after 4–6 weeks
- Duration of action on average 3 to 6 months
The jawline appears more refined, the face takes on a more V-shaped profile and complaints such as grinding or jaw tension often decrease significantly.
Is jawline treatment with botulinum toxin safe?
At Xavier Clinics this treatment is performed exclusively by BIG-registered physicians with extensive experience in injectables. We work with A-brand botulinum toxin and use a medical, safe, and natural approach. The goal is always harmony and balance, never a "frozen" appearance.
Botulinum toxin versus fillers in the jawline
Where fillers add volume or accentuate contours, botulinum toxin works relaxing and slimming. For some clients, we combine a jawline treatment with botulinum toxin and jawline fillers for an optimal and natural result. This combination is always individually and carefully tailored.
