How to get rid of a double chin:
what works, by cause

What causes a double chin?

A double chin is what you see, not what is producing it. Under the chin there are five separate contributors, and many people have more than one:

• Fat under the chin (submental fat), a soft layer that changes with weight and is partly inherited.
• Loose skin, which folds when you look down and becomes more common with age and after weight loss.
• The platysma muscle, the thin sheet across the neck, whose position and bands can blunt the angle under the jaw.
• A short or recessed chin, which shortens the line from chin to neck so the area looks full even with little fat.
• A salivary gland under the jaw that sits low or is enlarged, which is firm rather than soft.

That is why lean people can have a double chin, and why some people who lose weight see little change under the chin. The table gives a rough guide to which cause is likely to be the main one.

The anatomy of each cause is explained on double chin: what is actually under there and in the four causes that look identical.

How to reduce a double chin naturally: weight, posture and habits

How to reduce a double chin without treatment comes down to the causes you can influence: fat, posture and, to a degree, skin quality.

Weight

If fat leads and you are above your usual weight, losing weight overall helps, because the fat under the chin shrinks with the rest. Fat cannot be lost from one spot alone, so diet and exercise reduce it as part of the whole body, not selectively. If you are already at a healthy weight, further loss changes little under the chin and can hollow the face above it. Large swings in weight also stretch the skin, so a steady approach is kinder to the neck.

Posture

A forward head posture and looking down at a phone or laptop fold the soft tissue under the chin, so the area looks fuller than it is. Raising screens towards eye level, sitting back with the head over the shoulders, and holding the phone higher reduce how often the fold forms. In photographs, a camera held slightly above eye level, with the chin brought forward rather than up, changes the shadow a great deal. This is not a cure for fat or loose skin, but it can remove the part of a double chin that is posture.

Skin and general health

• Take sunscreen below the jaw and onto the neck daily; sun breaks down the collagen that keeps skin firm.
• Avoid smoking, which thins skin and weakens its recoil.
• A face that is puffy from salt, alcohol or poor sleep can look fuller under the chin; that kind of fullness comes and goes.

None of these changes a short chin, a gland or the platysma. Where those lead, home measures will not shift the shadow, and that is not a failure of effort.

“A double chin is a shadow with five possible causes. Diet helps one of them, posture helps another, and the rest need the cause named before anything is done.”

Do double chin exercises work?

Double chin exercises have little evidence behind them. Chin lifts, neck rolls, tongue presses and jaw exercisers work muscles, and exercising a muscle does not remove the fat lying over it. They do not shorten loose skin either. Some people notice that their posture improves when they practise them, which can soften the part of the shadow that comes from posture.

A few popular methods deserve a plain answer:

• Jaw exercisers and chewing devices. They strengthen the chewing muscles, which sit at the sides of the jaw rather than under the chin, and heavy use can strain the jaw joint.
• Mewing (tongue posture). There is no good evidence that holding the tongue against the palate reduces fat or tightens skin under the chin in adults.
• Neck exercises. They strengthen the platysma, whose pull contributes to banding, so they can work against the look you want.
• Chin straps, creams and wraps. They can reduce swelling for a while; they do not remove fat or tighten skin.
• Massage, rollers and gua sha. They can move fluid and reduce puffiness for a time without changing structure.

If you enjoy them, gentle exercises do no harm. The point is to know what they can and cannot change, so that time and money go to the cause that is actually there. The same honest view of facial exercise applies to the neck lines that often come with a double chin; see neck lift without surgery.

Double chin treatment by cause: what a doctor can add

When weight, posture and habits are not enough, a doctor matches the treatment to the cause. Fat-directed treatment does nothing for loose skin or a short chin, and skin tightening does not remove fat, so the cause decides the method. The full comparison is on double chin treatment.

Fat-dissolving injections and liposuction are not performed here; they are described so that you can weigh them. The published evidence for non-surgical fat reduction under the chin covers both cryolipolysis and deoxycholic acid (see the references below), and both act on fat alone. Reducing fat beneath skin that has lost its spring can make the area look looser, which is why skin recoil is checked first.

When fullness under the chin is not a double chin

Most fullness under the chin is fat, skin, muscle or chin shape. Some is not, and those causes need a doctor rather than a cosmetic treatment.

• Salivary glands under the jaw can sit low or enlarge, giving a firm fullness at the sides that does not pinch like fat.
• Lymph nodes can swell with infection and sometimes for other reasons.
• The thyroid sits lower, at the front of the neck, but a goitre can make the neck look full.
• A lipoma or cyst forms a distinct lump with an edge you can feel.

See a doctor promptly if

• a swelling is new, firm, growing or on one side only;
• it is tender, red or comes with fever;
• you have difficulty swallowing, a change in your voice or unexplained weight loss.

Two other lookalikes are cosmetic but are not a double chin. Jowls sit along the jawline beside the chin rather than under it; see jowls and lower face sagging. A loose, banded neck below the chin is a neck question, with its own options. A double chin treatment applied to either changes the wrong thing.

How Dr Sin Yong finds the cause, and the next step

Dr Sin Yong examines the area himself on Orchard Road. He looks from the front and in profile, at rest and with the head tilted forward and back, because fat, loose skin and a short chin behave differently as the neck moves. A gentle pinch shows how much is fat and how much is skin. Tensing the neck shows the platysma. Pushing the jaw forward shows how much a short chin contributes. Weight history, thyroid or other conditions, medicines and earlier treatment are recorded.

The plan comes in writing: what is producing the fullness, what each option can and cannot do, and the option of no treatment. Some assessments end with advice on posture or weight rather than treatment, and some with a referral for a medical or surgical opinion.

Before an assessment

• Bring photographs in profile, ideally from a time when you were happy with the area.
• Note any recent change in weight and any thyroid condition.
• Mention earlier injections, threads or surgery in the face or neck.
