How to Make Your Jawline Sharper: What Works, What Doesn't and When to Consider Surgery

A sharp, well-defined jawline is one of the most searched-for facial features, and social media is full of quick fixes that promise one. Some of them help a little, some have no evidence behind them, and a few can cause problems.

This guide explains what gives a jawline its shape, which natural steps can make a difference, what the evidence says about jaw exercises, mewing and chewing gum, and when fillers or surgery are worth discussing.

What makes a jawline look sharp?

A jawline looks sharp when there is a clear line between the jaw and the neck. Several things affect that line:

• Bone structure: the size and shape of your jaw and chin, which are largely inherited.
• Fat: fat under the chin and along the lower face can soften the line.
• Skin: as skin loses elasticity with age, it can sag below the jaw.
• Muscle: the chewing muscles at the back of the jaw affect the width of the lower face.
• Posture: the position of your head and neck changes how your jaw looks.

Some of these can change and some cannot. Knowing which one affects you is the first step to choosing what will help.

How to make your jawline sharper naturally

Lose excess body fat

If you carry extra weight, losing body fat is often the most effective natural way to make your jawline look sharper. You cannot choose to lose fat from your face alone, but overall weight loss usually reduces fat in the face and neck too. A balanced diet and regular exercise are the basis.

If you are slim and still have fullness under your chin, genetics or anatomy may be the reason. Our guide on how to get rid of a double chin naturally explains why this happens.

Improve your posture

Holding your head forward, for example when looking down at a phone, can make the area under your chin look fuller. Sitting and standing with your head level and your shoulders back can make your jawline look more defined. This changes how your jaw appears, not its structure.

Use grooming and make-up

A well-shaped beard can create a sharper line along the jaw. Contouring make-up, with a darker shade under the jawline and a lighter one above it, can give a similar effect. Neither changes your face, but both can make a visible difference.

Do jawline exercises work?

There is little evidence that they do. Jaw exercises and jaw-exerciser devices are widely promoted, but they have not been well studied. In one published case report, two people used a jaw-exercising device for about three months and neither noticed a change in how their jaw looked. The authors concluded that these products may have limited effect.

The chewing muscles that jaw exercises work do not reduce fat under the chin or tighten loose skin. Exercises for the neck and posture may help you hold your head better, which can improve how your jawline looks.

Does mewing work?

Mewing means holding your tongue flat against the roof of your mouth, with your teeth together and lips closed, in the belief that this will reshape your jaw over time. It is popular online, but there is no good evidence that it works.

The British Orthodontic Society says it knows of no scientific evidence that holding the teeth and tongue in a closed position can change the shape of your face. Any difference people see in photos is more likely to come from posture, lighting or camera angle.

Does chewing gum make your jawline sharper?

There is no good evidence that chewing gum makes your jawline sharper. Chewing works the muscles at the back of the jaw, but it does not reduce fat under the chin or tighten skin.

Chewing a lot can also strain your jaw. If you have jaw pain or a clicking jaw, the NHS advises not to chew gum.

Non-surgical treatments for a sharper jawline

Dermal fillers

Fillers are injected along the jaw or chin to add definition and shape. The NHS says fillers are not permanent and usually last around 6 to 18 months, depending on the filler and the area treated.

Serious problems are uncommon, but they include infection, lumps, filler moving away from where it was injected, and blocked blood vessels, which can cause tissue damage and, rarely, blindness. Choose a qualified medical practitioner and ask about their training before you book.

Injections for a wide lower face

Some people have injections into the chewing muscles at the back of the jaw to make the lower face look slimmer. This narrows the face rather than sharpening the jawline, and the effect wears off. It should only be given by a qualified practitioner after an assessment.

Surgical options for a sharper jawline

Surgery is usually considered when the jawline is held back by a structural problem that natural steps cannot change.

Chin implant or chin surgery

A small or set-back chin can make the jawline and neck look less defined. A chin implant adds projection, while genioplasty moves or reshapes the chin bone itself. The American Society of Plastic Surgeons describes chin surgery as a way to improve the balance between the chin, jaw and the rest of the face. Read more about chin implants.

Neck liposuction

If fat under the chin softens your jawline despite a healthy weight, liposuction can remove it through small incisions. It works best when the skin is still firm enough to tighten afterwards.

Neck lift

When loose skin or neck bands are the main problem, a neck lift removes excess skin and tightens the tissues beneath it. It is often combined with liposuction or a facelift. Read more about a neck lift.

Jaw surgery

Surgery to move the upper or lower jaw, called orthognathic surgery, is mainly used to correct problems with the bite and jaw function. It can change the shape of the face, but it is a major operation and is planned together with orthodontic treatment.

Every operation has risks, recovery time and scars, and results vary. Only a surgeon who has examined you can say whether surgery is suitable.

Which option might suit you?

How long does it take to get a sharper jawline?

It depends on what you change. Weight loss and posture changes take weeks to months, and the result depends on your starting point. Fillers show their effect straight away but wear off. After surgery, swelling usually needs weeks to settle, and the final result can take several months to appear.
