Jawline Definition


Jawline Definition

What is this ?

Thanks to minimally invasive techniques, it is now possible to achieve a defined jawline. At MRockland Dermesthetic Clinic, we develop personalized treatment plans to correct the lack of contour or to modify the jawline’s definition.

What is Jawline Definition ?

Jawline definition refers to the angle of the jaw and the mandibular line. Both men and women can suffer from a lack of definition in this part of the face. While for some individuals, this physical detail poses no problem, for others, it is necessary to harmonize and redraw the oval of the face. In this case, it is then advisable to redefine the contours of the jawline.

Causes of Jawline Definition Loss

Several elements, whether genetic or not, interfere in the loss of jawline definition. Here are the leading causes :

  • Age : the weight of age can lead to skin sagging and a weakening of the facial muscles, which causes the loss of jawline definition.
  • Genetics : the genetic baggage received from your parents can be responsible for poorly defined jaws, as it plays a significant role in the distribution of facial fat and the size and shape of facial muscles.
  • Body fat percentage : excess fat around the neck can obscure the definition of the jawlines.
  • Muscle tone : underdevelopment or weakness of the temporal muscle (responsible for TMJ movements) can contribute to a less defined jawline.
  • Posture : By slouching or having your head forward, the skin under the chin can sag, leading to a less defined jawline.
  • Diet : a diet rich in salt and processed products can cause health problems like water retention and bloating, contributing to a softer jawline.

Finally, dehydration can make the skin duller and less elastic, also contributing to a less defined jawline.

Concerned Areas

Specific areas highlight a loss of definition in the contours of the face at the jawline, namely :

  • The lower face : fullness in this area can cause blending with the neck.
  • The chin : excess fat in the submental area (under the chin) can lead to the appearance of a double chin.
  • The jowls : as collagen breaks down, some sagging develops and causes an accumulation of skin around the jawline.
  • The platysma cords : this thin muscle layer can cause a cord-like appearance in the neck.

Aging-related collagen loss and excess skin due to weight loss can lead to sagging skin on the neck.

Non-Surgical Treatments

For those not wishing to undergo surgery, non-invasive treatments exist.

Filler Agents

Injections of filler agents help improve the contours of the chin and jawline. This mesotherapy technique is also very effective for treating chin dimples or creating a square jawline.


Composed of calcium hydroxyapatite microspheres suspended in a gel, Radiesse is an option not to be overlooked for immediate volume. Continuing to work several weeks after injections, it stimulates the natural production of collagen in the treated areas. Over time, Radiesse is completely absorbed by the body and leaves behind the patient’s natural collagen.

Micro-Needling RF Potenza

This treatment uses very small and thin needles and radiofrequency energy to penetrate the upper layer of the skin and trigger the body’s natural healing process to regenerate new collagen and elastin. Unlike other treatments, micro-needling RF Potenza is effective on all skin types and can be performed at any time of the year.

Neuromodulator Dysport

Derived from type A botulinum toxin, Dysport is used to treat expression wrinkles caused by the contraction of facial muscles. Dysport injection treatment is suitable for men and women wishing to reduce the visible signs of aging. It works by relaxing the muscles, making the skin smoother while reducing the appearance of wrinkles and fine lines.

Surgical Treatments

Surgical treatments exist to remedy this loss of jawline definition.

Facelift or Neck Lift

This surgical intervention is perfect for treating sagging skin, relaxed muscles, and excess fat. Aiming to tighten delicate tissues, it offers excellent results if you wish to modify your jawline to define it better.

Chin Augmentation

Patients with a naturally weak jawline may choose to modify it with chin implants placed through a small incision made inside the mouth.


Ideal for removing excess fat and revealing hidden contours, liposuction can eliminate a double chin. It only works on patients close to their ideal weight and with tight and elastic skin.

Jawline Definition, what's the Difference Between Men and Women ?


In women, the procedure aims to define the jawline by tightening the jowls to improve the oval of the face. In men, it helps to increase the volume of the jawline and masculinize it. While men prefer a superhero jawline, women seek to achieve a graceful and harmonious shape.

Can You Feel Pain in the Temporomandibular Joint After Jawline Definition ?


It is possible to feel a warming or different degrees of inflammation after a session. Regarding pain in the temporomandibular joint, it is felt in cases of dental malocclusion (the upper and lower teeth do not fit together properly). It can also occur in cases of bruxism, a disorder that involves clenching the muscles during sleep or grinding teeth.

What Results Can Be Expected from Jawline Definition ?


The fillers used offer instant results. Once injected, they restore the volume of sagging skin and fill in wrinkles or fine lines. Very versatile, these products can also correct asymmetry or a receding chin.

How Much Does Jawline Definition Cost ?


The cost of the procedure depends on the number of syringes to be injected. More syringes are required for a jawline with a mandibular angle than for a square jawline.
