Non-Surgical Jaw Reduction - Slimmer jawline naturally

Yes, you can make your jaw smaller without surgery through a non-surgical procedure called masseter Botox. This treatment involves injecting Botox into the masseter muscles, which are responsible for chewing and clenching the jaw. By relaxing these muscles, the jawline can appear slimmer and more contoured.

How does masseter Botox work?

When you chew or clench your jaw, the masseter muscles contract and become larger over time. This can result in a square or overly prominent jawline. Masseter Botox works by temporarily paralyzing the masseter muscles, preventing them from contracting and reducing their size. The result is a softer, more feminine or masculine jawline, depending on your desired outcome.

What is the procedure like?

The masseter Botox procedure is quick and relatively painless. Your dermatologist will first assess your jawline and determine the appropriate dosage of Botox. Then, using a fine needle, they will inject the Botox into specific points along the masseter muscles. You may experience a slight pinch or discomfort during the injections, but it is generally well-tolerated.

When will I see results?

It typically takes a few weeks to start seeing the effects of masseter Botox. As the Botox starts to take effect, you will notice a gradual reduction in the size of your jawline. The full results are usually visible within 4-6 weeks after the treatment.

How long does masseter Botox last?

The effects of masseter Botox can last anywhere from 3 to 6 months. However, individual results may vary. To maintain the desired jawline contour, you will need to repeat the treatment every few months.

Are there any side effects?

Masseter Botox is generally safe and well-tolerated. However, like any medical procedure, there can be potential side effects. The most common side effects include temporary swelling, bruising, or redness at the injection site. These usually subside within a few days. In rare cases, there may be temporary weakness or difficulty chewing, but this is uncommon and typically resolves on its own.

Is masseter Botox suitable for everyone?

Masseter Botox is a suitable option for individuals who want to achieve a slimmer jawline without undergoing surgery. It is particularly popular among those with a square or prominent jawline. However, it is important to consult with a qualified dermatologist to determine if you are a good candidate for the treatment.


If you are looking to make your jaw smaller without surgery, masseter Botox can be an effective and non-invasive option. By relaxing the masseter muscles, this treatment can help you achieve a more contoured and balanced jawline. Consult with a skilled dermatologist to discuss your goals and determine if masseter Botox is right for you.
