A square jaw refers to the lower jaw area jutting out to the side, often due to an enlarged masseter muscle at the jaw's angle. This can create a bulkier appearance and may distort the natural facial aesthetics. Depending on the individual's preference, some may seek to alter their square jawline to achieve a more balanced look. There are several treatments available, both surgical and non-surgical, to address this concern.

What Causes a Square Jaw?

Masseteric Hypertrophy

Masseteric hypertrophy, also known as "square face," is the enlargement of the masseter muscles at the jaw's angle. This muscle is one of the strongest in the human body, used daily for chewing and speaking. Overuse can lead to a hypertrophic (enlarged) appearance, often perceived as masculine, especially in women.

Congenital Factors

Some individuals have a naturally larger mandible, contributing to a square jaw appearance. Unlike masseteric hypertrophy, this condition does not respond to the same treatments and may require different approaches.

How to Get a Square Jaw

For those seeking a square jaw, specific exercises, and lifestyle changes can enhance jawline definition. However, most individuals focus on reducing a square jaw rather than achieving one.

Treatment Options for a Square Jaw

Non-Surgical Treatments

Botox® and Xeomin® Injectables like Botox® and Xeomin® can temporarily reduce the size of the masseter muscles, leading to a narrower jawline. These treatments cause the muscles to relax and atrophy over time, making the jaw appear less bulky. Results typically last up to four months and may become less frequent with continued treatments.

Surgical Treatments

Jaw Reduction Surgery is For more permanent results, surgical options are available. Jaw reduction surgery involves reshaping the jawbone to create a more tapered look. This procedure carries risks, including potential injury to the facial nerves or salivary glands, and requires significant recovery time with swelling and discomfort.

How to Get Rid of a Square Face

Lifestyle Changes

  • Avoid Excessive Chewing: Reduce habits like chewing gum or hard foods that can enlarge the masseter muscles.

  • Manage Teeth Grinding: Address nocturnal teeth grinding through dental interventions or stress management techniques.

Professional Treatments

Consulting with a cosmetic surgeon can help determine the best approach for reducing a square jaw. Non-surgical treatments like Botox® may be recommended first, with surgical options considered if necessary.

The Aesthetic Perspective

While some may view a square jaw as a strong and attractive feature, others may prefer a more rounded or V-shaped face. The perception of beauty is subjective, and treatments are available to help individuals achieve their desired look.

Famous Faces with Square Jaws

Many famous actresses and models have square jaws and are celebrated for their striking looks. This highlights the diversity in beauty standards and how individual features can be uniquely attractive.

Mewing: An Alternative Approach

What is Mewing?

Mewing involves maintaining proper tongue posture by resting the tongue against the roof of the mouth. This practice is believed to help in shaping the jawline and improving facial structure over time.

How to Practice Mewing

  • Correct Tongue Posture: Rest your tongue against the roof of your mouth, just behind the front teeth.

  • Consistent Practice: Practice mewing consistently to see gradual changes in jawline and facial structure.

  • Additional Benefits: Mewing can also improve breathing and overall oral health.


Understanding the causes and treatments for a square jaw can help individuals make informed decisions about their appearance. Whether through non-surgical methods like Botox® or surgical procedures, options are available to achieve a more balanced jawline. Consulting with a professional can provide personalized advice and treatment plans. Additionally, exploring practices like mewing can offer non-invasive ways to enhance facial structure.
