Your facial contour plays an important role in the overall appearance and balance of your face. While genetics largely determine the natural shape of your jaw, muscle size, facial volume, skin laxity and submental fat can all influence how defined your lower face appears.
For some people, the masseter muscles create a wider or more square lower face. Others may have a less defined jawline because of facial volume, a double chin or changes in skin laxity over time. Botox for jawline contouring is one option that can address a specific contributor to a wider lower face, while other treatments may be better suited to different concerns.
Understanding what is actually creating the appearance you want to change is the first step toward choosing the right treatment.
What Does Botox Do for the Jawline?
Botulinum toxin temporarily reduces activity in targeted muscles. In the lower face, one area that can be treated is the masseter muscle, a large muscle along the side of the jaw that helps with chewing.
You can feel the masseter contract if you place your fingers along the side of your jaw and clench your teeth. In some people, particularly those with naturally prominent or enlarged masseter muscles, reducing muscle activity can gradually create a slimmer appearance in the lower face.
Masseter treatment has also been studied for conditions involving masseter hypertrophy and jaw-related symptoms, although cosmetic treatment and treatment for conditions such as bruxism are not necessarily the same. Anyone experiencing significant jaw pain or teeth grinding should be evaluated by an appropriate medical or dental professional rather than assuming cosmetic Botox is the solution.
From a cosmetic perspective, reducing masseter prominence can make a broad or square lower face appear narrower. The degree of change depends on your individual anatomy, muscle size and the amount of muscle contributing to the shape of your face.
Botox for Jawline Contouring: Who May Benefit?
Botox for jawline contouring is most relevant when prominent masseter muscles are contributing to the width of the lower face.
If the jaw appears wide because of the underlying bone structure, Botox will not reshape the bone. Likewise, Botox will not remove excess fat under the chin or tighten significantly loose skin.
This is why a facial assessment is so important. Two people may both feel that their jawline is not defined enough but require completely different treatments.
What Is the Nefertiti Lift?
Another botulinum toxin technique for the lower face and neck is commonly called the Nefertiti Lift.
This treatment targets portions of the platysma muscle along the lower face and neck. The platysma is a thin, superficial muscle that can contribute to downward pulling along the lower face and visible platysmal bands in the neck.
By selectively reducing activity in portions of this muscle, an experienced injector may be able to create a more refined appearance along the jawline and neck in appropriately selected patients.
Research on the Nefertiti Lift has found improvement in platysmal bands and overall lower-face and neck appearance in some patients, particularly those with platysma hyperactivity and relatively good skin elasticity. However, results depend heavily on patient selection and injection technique.
The platysma is an anatomically delicate area, so this is not a treatment where more Botox necessarily means a better result. Proper knowledge of the anatomy is essential because inappropriate injections can cause unwanted effects such as weakness or difficulty swallowing.
What Else Can Define the Jawline?
Botox is only one option for improving facial contour. The best treatment depends on what is actually causing the lack of definition.
Dermal Filler for the Chin and Jawline
If the issue is a lack of projection or definition rather than prominent masseter muscles, dermal filler may be a better option.
Filler can be strategically placed around the chin and jawline to enhance projection and create greater definition. This can be particularly helpful when the underlying bone structure does not provide as much chin or jaw projection as a patient would like.
Results vary by product, treatment area and individual metabolism, and multiple syringes may sometimes be appropriate to achieve a specific contour.
The goal should be to enhance the natural proportions of the face rather than simply adding as much volume as possible.
Kybella for Submental Fat
If the concern is a double chin, treating the masseter muscles will not address the underlying fat.
Kybella is an injectable treatment containing deoxycholic acid that is FDA-approved for improving the appearance of moderate to severe fullness associated with submental fat in adults. It works by destroying fat cells in the treated area. Multiple treatments may be necessary.
Kybella is not approved for treating fat throughout the body or other facial areas. The FDA specifically warns against using deoxycholic acid injections outside the submental region.
Once fat cells are destroyed, they do not regenerate, but that does not mean the area can never change again. Remaining fat cells can enlarge with weight gain, and normal aging can continue to affect the appearance of the neck and jawline.
How Do You Know Which Treatment Is Right for You?
A more defined jawline can involve several different anatomical factors, including:
- Masseter muscle size
- Chin projection
- Jawbone structure
- Submental fat
- Skin laxity
- Facial volume
- Platysma muscle activity
For example, Botox for jawline contouring may be appropriate when prominent masseter muscles are making the lower face appear wider. Filler may be more appropriate when the goal is to enhance chin or jaw projection. Kybella may be considered when submental fat is contributing to a less defined jawline.
Some patients may benefit from a combination of treatments, while others may not need an injectable treatment at all.
Start With a Facial Analysis
There is no single injectable that creates a defined jawline for everyone. The most natural-looking results come from identifying what is actually contributing to the shape of the lower face and treating that specific concern.
During a consultation with Dr. Supriya Tomar, your facial anatomy, muscle activity, skin and volume can be evaluated to determine which non-surgical options may be appropriate for you.
