Is it possible to train the jawline?

A beautiful and tight jawline is a beauty ideal for both men and women. This causes more and more people to choose to train their jawline. They hope that this will make it more visible.

For women, this often means tightening the jawline. For men to make it wider or more muscular. However, is it possible to train a jawline? Or is the only option that really helps a visit to a surgeon?

In this blog, we explain what does and what does not help to get your perfect jawline.

Training a tight jawline, why?

More and more people are dissatisfied with their own appearance. This is partly due to the access to the internet on which people are shown who meet a beauty ideal. One of these ideals is having a clearly visible and clean jawline. Jawline training seems like a daily activity for these people, but in reality, it will be very different.

It is genetically determined how your jawline is shaped. There is also a good chance that photos will be edited. The person in question has a less visible jawline in real life. So before we dive deeper into the subject, it's important to understand that the options for training and altering your jawline are limited. Your jawline mainly depends on the shape of your face and can therefore only be changed to a limited extent.

As you read on, you'll find information about the most important muscle in the jaw that can play a role in the appearance of your jawline. Then we discuss a number of studies that have investigated the effect of jawline training. This way we can determine what you can possibly achieve with jawline training.

Anatomy of the chewing muscles

When we eat something we always use our chewing muscles. The human body has four different chewing muscles, namely:

  • muscle masseter
  • Lateral pterygoid muscle
  • pterygoid muscle medial
  • Temporal muscle

The most important of these four muscles (when it comes to jawline training) is the masseter muscle. This muscle is also known as the cheek chewing muscle. When you chew on something, you use the musculus masseter. Most of this muscle is in your cheek near your jawline. When this muscle gets bigger, which is possible, your jawline also looks wider. This may not be the desired effect for women, but it will be for many men.

Jawline Training Studies

Several studies have been completed on training the muscles in the jaw. We will elaborate on some of the findings here. In this way, we can paint a clear picture of the effect of exercises on the jaw muscles on the jawline. We can therefore also conclude from this whether your effect can train your jawline.

Size of jaw muscles related to other muscles

A 2004 study analyzed 121 adults to see if there was a relationship between jaw muscles and muscles in the limbs. One of the conclusions they could draw was that the size of the jaw muscles was clearly related to the size of the muscles in the limbs. This suggests that the muscles in the jaw are affected in the same way as the muscles in our limbs.

Jawline training was therefore not directly applied here. It, therefore, seems that people who have more muscle mass in their limbs also (indirectly) have larger jaw muscles. It is not mentioned here whether the test subjects performed muscle-strengthening exercises or whether they had more muscle mass on their own.

Isometric training of the masseter muscle

A 2001 study of 28 young adults concluded that isometric exercises could significantly increase bite force. However, the masseter muscle turned out to be more difficult to train in this way. After six weeks, the activation of the muscle decreased, making it more difficult to train. A larger muscle masseter will give the effect of a wider jawline. That is mainly the purpose of jawline training for men. The effect of doing these exercises for longer than 6 weeks has not been studied, so the effect this has on the muscle masseter is unknown.

When doing isometric exercises for the jaw muscles, you let them contract, but no further moving component is added. So it is bitten and this is then held for a few seconds. This study, therefore, does not take into account doing other exercises to train the jawline, only isometric exercises.

Effect of exercise in the elderly

A 2014 study analyzed the effect of muscle-preserving exercises on the face and concluded that it may be especially important for the elderly. These were people who wanted to visit a dental clinic for aesthetic reasons. Doing such exercises can have a positive effect on the muscles and the position of the lower jaw.

Exercises centered on smiling also had a positive effect not only on the position of the lower jaw but also on the geniality of the test subjects. So the study finally concluded that it is possible to change the jawline to some extent. The exercises made the jawline look more aesthetically pleasing. According to this study, training the jawline is possible (to a certain extent). These smile exercises are likely to have little effect on younger people who use the muscles in their faces a lot on a daily basis.

The fat percentage can be of great importance

The height of your body fat percentage can play a major role in the visibility of your jawline. When you have a higher fat percentage, a (small) part of this will also be in your face. This can make your jawline look less defined and therefore less visible. So even if you have a genetically good jawline, a high-fat percentage can still throw a spanner in the works.

It is also not possible to burn fat locally, so you cannot only burn fat in your face by training your jawline. For this, you will really have to reduce the fat percentage of your entire body. However, it is also genetically determined where the fat positions itself in your body, and even with a low-fat percentage, your jawline may not be clearly visible. It is therefore not a given that you will get a clearly visible jawline if your fat percentage is low.

Jawline training: the conclusion

Your jawline largely depends on the shape of your face and is therefore genetically determined. You cannot change this. In addition, your fat percentage also plays a role, since with a lower fat percentage the jawline will be more visible.

Training your jawline (and increasing the masseter muscle) by doing exercises is then only a very small percentage of the entirety of aspects that influence your jawline. There is insufficient evidence that doing exercises for the jawline can actually increase the muscle masseter. In addition, there is also insufficient evidence of whether this can tighten the jawline. That is why we are not going to mention exercises in this blog that would improve the jawline since it is unclear what the long-term effects are.

What we can say is that you train the muscles in your face when you have to smile, so keep smiling a lot.
