Jaw Muscle Botox Information

Face Slimming

Many women feel self-conscious about having a “strong” or “masculine” facial appearance. This look is often influenced by certain features for example, a broad forehead or a wide jaw is commonly associated with a more masculine look. A prominent jawline can sometimes be caused by an enlarged jaw muscle, known as the masseter muscle. Botox can be used to relax this muscle, which reduces its size over time and gives the face a slimmer appearance. This treatment is also used as part of facial feminization. Slimming the jawline in this way is often referred to as face slimming.

Masseter Botox

The muscle responsible for closing the jaw is called the masseter. Often referred to as the chewing muscle, it can become enlarged through jaw clenching, teeth grinding (bruxism), or frequent chewing of gum. As the muscle grows stronger, it also becomes thicker, which can affect the shape of the face. This may give the appearance of a wider jaw or fuller cheeks. In many cases, the muscle is enlarged on both sides, though it can also occur on just one side, leading to facial asymmetry.

Masseter Botox treatment

The masseter muscle can be treated with Botox. This helps reduce jaw clenching and teeth grinding, meaning the muscle is less overworked and gradually reduces in size. As the muscle thins, the face takes on a slimmer appearance. A treatment typically lasts around 3–6 months, after which you can choose whether to have it repeated.

Jawline slimming with Botox

A wide jawline is sometimes the result of an overdeveloped jaw muscle. This can happen through habitual behaviors like gum chewing, or simply because of muscle overactivity. Botulinum toxin can be used to relax the muscle safely, without affecting normal function. Over time, the muscle becomes slimmer, giving the face a softer, more contoured look. The results usually last about 16 weeks. For the best outcome, make sure you consult an experienced aesthetic practitioner.

Jaw Muscles

Jaw muscles are essential for chewing food and for opening and closing the mouth. In some people, however, these muscles can become overactive. This may be due to clenching the jaw as a habit, developing a tic, or chewing gum too often. In such cases, treatment with botulinum toxin can be a helpful solution.

Masseter Botox cost

Jaw muscle treatment typically costs between £160 and £340. Prices vary depending on the clinic, so it’s worth comparing options to find the best fit for you.

A More Feminine Face

In recent years, aesthetic medicine has developed into a recognized medical specialty, thanks to the professionalization of the field over the past two decades. Years ago, only a handful of doctors in the UAE focused on injectables, and people mainly went to smooth out a few wrinkles. Today, the approach is much more advanced. Experienced practitioners don’t just look at the signs of ageing but also at someone’s overall facial expression and appearance. Many people feel their face doesn’t match how they truly are they may appear stern, tired, dominant, or unapproachable, even when that isn’t the case. A strong, square jaw for example, often gives a dominant or masculine look. While this may suit some, others such as women and transgender individuals may feel uncomfortable with it.

A wide jawline can often be treated effectively. If the cause is an enlarged jaw muscle, a simple Botox treatment can make a big difference. Overdeveloped jaw muscles may result from clenching, grinding teeth, excessive gum chewing, or simply genetics. Relaxing this muscle helps soften the face and create a more feminine contour.

Fillers for a softer, more feminine appearance

Fillers can also be used to create a more feminine look. By adding subtle projection to the chin and the start of the jawline, the face appears more V-shaped. Although the changes are minimal, the overall result can be striking yet natural. Think of it more as sculpting the eye is gently drawn away from stronger features, creating balance and harmony. The same applies to fillers in the zygomatic area—the region between the ear and cheekbone. Adding volume here helps lift the skin, shifting the focus upwards and giving the face a softer, more feminine expression. An experienced aesthetic practitioner can advise you in a consultation on which treatment would best suit your face and your personal goals.

Causes of an Enlarged Jaw Muscle

An enlarged jaw muscle can be the result of genetics or because the muscle has been “overtrained.” This happens through habits such as night-time teeth grinding (which often stops after treatment), jaw clenching, or chewing gum excessively. Teeth grinding and clenching can themselves be linked to sleep disorders, periods of anger, stress, or the use of drugs, alcohol, or medication. In all cases, there is overactivity of the chewing muscles.

Treating the Jaw Muscle with Botox

Botox is one of several brands of botulinum toxin—others include Bocouture and Azzalure. An enlarged jaw muscle is often associated with a more masculine facial appearance. During treatment, 3–5 virtually painless injections with a fine needle are placed into the large jaw muscle (masseter). If there is also pain or excessive tension in the temporalis muscle (another chewing muscle), this can be treated as well. Your jaw will continue to function normally after the procedure—only the grinding and clenching are reduced. The treatment is effective for around 3–4 months and is also commonly referred to as Face Slimming.

Scientific evidence for Masseter Botox treatment

A Masseter Botox treatment relaxes the masseter muscle, which refines the jawline and reduces tension. Botox blocks nerve signals by inhibiting SNAP-25, temporarily reducing the muscle's contraction force. It is biocompatible and is broken down by the body. Clinical studies confirm its safety and effectiveness (Kim et al., Plast Reconstr Surg, 2016).
