Masseter Botox: a Slimmer Lower Face
If you've ever looked in the mirror and wished your jawline were a little softer, a little more contoured — you're far from alone. A wide or square jaw is one of the most common facial concerns we hear about at Karwal Aesthetics, and it's often caused by something surprisingly simple: overactive masseter muscles.
The good news? You don't need surgery to address it.
What Is Masseter Botox?
The masseters are the powerful muscles on either side of your jaw responsible for chewing and clenching. In many people — particularly those who grind their teeth or clench under stress — these muscles become enlarged over time, creating a wider, squarer jawline.
Masseter Botox works by gently relaxing these muscles with small, precisely placed injections of botulinum toxin. As the muscle activity reduces, the jaw gradually slims and softens, revealing a more tapered, balanced facial profile.
It's one of the most requested treatments in aesthetic medicine worldwide, and for good reason — the results are subtle, natural, and genuinely transformative.
What Does the Treatment Involve?
This is one of the quickest treatments we offer. The entire appointment takes around 10 to 15 minutes, with no downtime at all. A few small injections are placed into each masseter muscle, and you're free to carry on with your day immediately afterwards.
Most patients begin to notice a difference within the first week or two as the muscles start to relax. The full slimming effect typically develops over the following four to six weeks as the muscle gradually reduces in size.
Who Is It For?
Masseter Botox is ideal if you:
Feel your jawline appears too wide, heavy, or square
Want a slimmer, more V-shaped facial contour
Grind or clench your teeth (bruxism) and experience jaw tension or headaches
Would like to improve facial symmetry without surgery
It's worth noting that masseter Botox also offers real functional benefits. Many of our patients come in primarily for jaw pain or teeth grinding and are pleasantly surprised by the aesthetic improvements as well.
How Long Do Results Last?
Results typically last between four and six months. With repeated treatments, many patients find the effects last progressively longer as the muscle becomes trained to stay in a more relaxed state.
