How does Botulin Toxin work and is it a safe treatment for jaw reshaping?
Botulinum toxin type A (BTTA) is a neurotoxin that has the ability to block the nerve activity in the muscles, causing a temporary reduction in muscle activity which in turn reduces the size of the muscle. As with any medical intervention careful analysis of the anatomy of the masseter muscle, in addition to skillful and precise placement of the neurotoxin are critical in achieving safe and aesthetically pleasing results. The toxin can soften the masseter muscle in a gradual fashion and without altering its function.
How long does it take to notice masseter slimming?
Patients typically notice softening of the masseter muscle at two weeks and reshaping of the jawline at six to twelve weeks. The treatment is staged as it is important to remodel the muscle in a staged fashion. Usually 20-25 Units are injected in each muscle and in a customized pattern to avoid localized hypotrophy. With two injections spaced three months apart most patients will achieve the desired effect with annual top ups to maintain the reshaped contours.
Can Masseter remodeling be combined with other treatments?

Reducing the thickness of the masseter can also contribute to a higher projection of the cheekbones, as the treatment slims the lower third of the face.
