Success Stories

Double chin reduction starts with working out what lies under the chin, because submental fat, loose skin and a lax platysma each call for a different approach. This earlier article describes non-surgical options, including Time Freeze Laser LCLR® and radiofrequency-based 4K Body Lift, offered by Dr Sin Yong to suitable candidates after assessment.

Key takeaways
  • Double chin, or submental fullness, can come from localised fat, skin laxity, a lax platysma or a receded jaw.
  • Each cause needs a different approach, so examination comes before a treatment is chosen.
  • Non-surgical options named here are Time Freeze Laser LCLR® and the radiofrequency-based 4K Body Lift, offered to suitable candidates.
  • Treatment cannot address heavy skin excess or a receded jaw, which are referred on.
  • Dr Sin Yong, an aesthetic physician, assesses and performs treatment, and refers surgical cases to a plastic surgery specialist.

Double Chin Reduction

A double chin is among the most common and recognisable facial concerns — visible from all angles, difficult to conceal and resistant to diet and exercise in most cases. While weight gain contributes, genetics plays a strong role — many patients with a healthy body weight still have significant submental fat accumulation due to their inherited fat distribution pattern.

Treatment Options for Double Chin

Time Freeze Laser — laser energy contracts the neck skin and lifts the double chin through collagen remodelling, reducing both the fat volume and the skin laxity that contributes to the appearance.

4K Body Lift — targeted radiofrequency to the submental fat pad. Directed at compact, well-defined double chin fat; recovery is discussed at consultation.

3D Facial Reconstruction — for more significant submental fat with concurrent skin laxity, surgical radiofrequency can address both components simultaneously with longer-lasting structural results.

The cervicomental angle — the angle between the chin and neck — is one of the most important determinants of the perceived age and attractiveness of the neck profile. Reducing the double chin dramatically improves this angle, often more visibly than any facial treatment.

Who it suits, who should wait, who is referred on

Tends to suit

  • Compact, well-defined submental fat
  • Mild skin laxity under the chin
  • People who prefer to avoid surgery and accept gradual change
  • Patients at a stable, healthy weight

Better to wait

  • Pregnancy or breastfeeding
  • Active infection or inflammation in the neck or under the chin
  • A goal that depends on a major change in neck shape, or recent significant weight change

Referred on

  • Heavy skin excess or prominent platysmal bands → surgical assessment
  • A receded chin or jaw → chin filler or surgical assessment
Who should not have this treatment
  • Pregnancy or breastfeeding
  • Active infection, inflammation or open wounds in the treatment area
  • Implanted electronic device, considered individually for radiofrequency
  • Unassessed lump or swelling in the neck, which needs a medical review first
  • Active skin disease or recent resurfacing in the area

People with heavy skin excess, prominent platysmal bands or a receded jaw tend to respond poorly, because non-surgical energy treatment is the wrong tool for those causes.

What happens, step by step

  1. Consultation and examination of fat, skin, platysma and jaw
  2. Written plan and quote, naming the cause and the energy chosen, or a referral if surgery suits better
  3. Treatment day: the area is cleansed and energy is delivered to the planned zones
  4. Review and adjustment, including whether further treatment is advised

Risks, side effects and when to call

Expected effects include warmth, redness, swelling and tenderness in the treated area. Fat is cleared by the body gradually, so the change is not immediate and varies between people. Less commonly, uneven contour, prolonged swelling, nodules or skin marking can occur, and numbness or altered sensation is possible. Because submental fullness can come from fat, laxity, platysma or the jaw, treating the wrong cause may bring little change. Weight gain can enlarge remaining fat cells, so stable weight matters. Assessment decides whether treatment is suitable and which energy is appropriate.

Contact the clinic the same day if
  • Blistering, crusting or an open area on the skin
  • Increasing pain, redness or heat that is not settling
  • Swelling that is increasing or becomes uneven
  • Numbness or weakness in the lower face that persists
  • Fever or signs of infection

See what to do if something feels wrong after a treatment.

Aftercare

First 24 hours

  • Keep the area cool and gently cleansed
  • Avoid heat such as saunas, hot showers and vigorous exercise
  • Avoid pressing or massaging the area unless advised

First week

  • Use a gentle moisturiser and avoid irritating products on the area
  • Avoid facials, peels and other devices on the neck until advised
  • Keep to a stable weight and report anything unusual at review

Sun

  • Apply broad-spectrum sunscreen daily and avoid direct sun on the treated area

Skincare

  • Resume retinoids and exfoliating acids only when the clinic advises

When to call

  • Blistering, crusting, increasing pain or spreading redness
  • Swelling that increases or becomes uneven, or numbness that persists

Before you book

  • Declare any implanted electronic device, metal implants or pacemaker
  • Tell us about pregnancy, breastfeeding and any recent weight change
  • Mention blood thinners, aspirin, fish oil or supplements that increase bruising
  • Avoid fresh sun exposure and pause strong skincare actives on the area as advised
  • Bring side-profile photos, recent weight records and a list of previous neck or chin treatments

What determines the fee

The fee depends on the cause of the fullness, the area treated, the device chosen, the number of passes or zones, and whether it is combined with another treatment such as a lifting or contouring plan. The plan is set after assessment rather than as a fixed course. A written quote is given at consultation, and the consultation also decides whether treatment is advised at all, or whether a surgical opinion or a different approach would suit you better.

How quotes work at this practice: how we quote.

Myths we hear in clinic

“A double chin always means excess weight.”

Genetics, skin laxity, platysma and jaw shape contribute, so even slim people can have submental fullness.

“One treatment suits every double chin.”

Fat, a lax platysma and a receded jaw each produce the same silhouette and need different approaches.

Frequently Asked Questions

What causes a double chin?+

A double chin (submental fullness) is caused by a combination of localised fat under the chin, skin laxity, and sometimes the position of the hyoid bone or platysma muscle. It can occur even in slim individuals due to genetic fat distribution.

How is a double chin reduced without surgery?+

The 4K Body Lift delivers targeted radiofrequency to the compact submental fat, aiming to reduce it while tightening the overlying skin, without surgery. The degree of change varies and is discussed at consultation.

How many sessions are needed for double chin reduction?+

The number of sessions is planned individually at consultation, spaced about 6 weeks apart. Treated fat is cleared by the body gradually over the following weeks.

How long do double chin reduction results last?+

How long the change lasts varies; the body clears the treated fat cells over time. Maintaining a stable weight preserves the result, as remaining fat cells can still enlarge with significant weight gain.

How much does double chin reduction cost in Singapore?+

The cost depends on the cause of the fullness, the area treated, the device chosen, the number of passes, and whether treatment is combined with another plan. A written quote is given at consultation after examination, and the consultation also decides whether non-surgical treatment is advised at all or a surgical opinion would suit you better.

Is double chin reduction worth it?+

It can be worthwhile for compact submental fat with mild laxity in someone at a stable weight who prefers to avoid surgery and accepts gradual change. It is not suited to heavy skin excess, prominent platysmal bands or a receded jaw, where a surgical opinion or a chin filler may suit better. Examination decides which applies.

How long does double chin reduction last?+

No duration is promised. How long the change is noticed depends on the cause of the fullness, the energy used, your skin quality, weight stability and genetics, because remaining fat cells can enlarge with weight gain. Review timing, and whether further treatment is advised, are set at consultation and revisited after assessment.

What are the disadvantages of double chin reduction?+

Change is gradual and varies between people, and treatment cannot address heavy skin excess or a receded jaw. Warmth, redness and swelling are expected, and less commonly contour irregularity, nodules or altered sensation can occur. Weight gain can enlarge remaining fat cells, and treating the wrong cause may bring little change.
