Learn more about wide jaws...

A wide jaw is often due to genes, having naturally large masseter muscles, the muscles in the lower jaw we use for chewing. In some cases, a wide jaw can also be caused by frequent jaw clenching which also enlarges the masseters muscles, which can leave an appearance of the face looking wider and more masculine. With the same treatment to prevent jaw clenching, botulinum toxin injections are popular treatment options used to shrink the size of the masseter muscles and improve the appearance of the jaw.

Botulinum Toxin are toxins injected into the body in small doses to temporarily relax the muscle. Small doses of Botulinum toxin such as those used in cosmetics are safe. It earned the approval of Food and Drug Administration (FDA) for optional treatment of wrinkles in 1989, and botulinum toxin type A was also later approved by FDA in 2002. This treatment works by blocking signals from the nerves to the muscles, making the injected muscle unable to contract. As a result, it makes conditions such as wrinkles relax and soften. Because of their aesthetic benefits, it has become one of the most commonly used treatments in cosmetics. Botulinum injections can be harmful in the hands of an amateur injector, that's why it's incredibly important to seek a credible aesthetician when performing the treatments.
