What Is Jaw BTX ?
Jaw BTX is a non-surgical jaw reduction treatment that relaxes the masseter muscles — the thick muscles at the side of your jaw responsible for chewing. When these muscles are overly active or large, they can give your face a wider, more masculine appearance.
By gently relaxing these muscles with BTX, we help reduce the bulk, giving you a slimmer face, sharper jawline, and enhanced facial symmetry.

FAQ for Jaw BTX
What is Jaw BTX, and how does it work?
Jaw BTX is a non-surgical treatment that involves injecting BTX into the masseter muscles to relax and slim the jawline. Over time, this reduces bulk in the lower face, helping you achieve a sharper, more contoured look.
How long does the treatment take?
The procedure typically takes 10 to 15 minutes, making it a popular lunchtime treatment. You can return to your daily routine immediately after.
Is Jaw BTX painful?
Most patients experience only mild discomfort, similar to a quick pinch. A numbing cream can be applied beforehand to ensure your comfort.
When will I see results?
You may start noticing subtle changes in 2 to 4 weeks, with full slimming effects visible around 6 weeks post-treatment.
How long do the results last?
Results typically last 4 to 6 months, depending on your muscle strength and metabolism. With consistent treatments, results may last longer over time.
Can BTX help with teeth grinding and jaw clenching?
Absolutely. BTX is frequently used to alleviate bruxism and jaw tension, offering both cosmetic and therapeutic benefits.
Is there any downtime after the procedure?
There’s no downtime. You can resume your daily activities right away, though it’s recommended to avoid strenuous exercise or facial massages for 24 hours.
Is Jaw BTX safe?
Yes, when performed by our MOH-certified doctors using high-quality products, Jaw BTX is a safe and effective treatment with minimal side effects.
How many sessions do I need?
Most patients start with a single session, but for long-term results or stronger masseter muscles, follow-up treatments every few months may be recommended.
Can men also get Jaw BTX?
Definitely. Jaw BTX is suitable for both men and women looking to slim their face, soften a square jawline, or reduce jaw-related tension.
