These silicone jawline exercisers are to help strengthen and tone the muscles in your jaw, which can lead to a more defined jawline. These exercisers help to:
More defined jawline: The main claim is that these exercisers can help to strengthen the masseter muscles, which are the muscles that give your jaw its definition. By strengthening these muscles, you may be able to achieve a more chiseled jawline.
Reduced facial fat: Some proponents of jaw exercisers also claim that they can help to reduce facial fat. The theory is that by working the jaw muscles, you will burn more calories in your face, which can lead to a slimmer appearance.
Improved jaw function: Jaw exercisers may also help to improve jaw function, which can be beneficial for people who have TMJ (temporomandibular joint) disorders.
