LIPOSUCCION MÉDICALE DU
DOUBLE CHIN

Dernière mise à jour : 16 July 2026

What is a double chin?

A double chin is fullness beneath the chin affecting men and women at any age. Usually caused by excess fat, any chin or neck fullness can create a second-chin appearance with lost jawline and facial contour definition.
Fat accumulation may accompany laxity or insufficient bone projection. Weight is not the only cause: genetics, ageing, reduced elasticity and chin morphology matter. Treatment is personalised and may combine cryolipolysis with hyaluronic acid to project the chin and redefine the jawline.

Key facts about a double chin

  • Definition: submental fat accumulation, sometimes with laxity or an underprojected chin.
  • Main causes: genetics, ageing, weight gain, elasticity loss or chin anatomy.
  • .
  • Treatments: cryolipolysis, chin and jawline hyaluronic acid injections.
  • Session duration: 30 to 60 minutes depending on technique.
  • Results: gradual after cryolipolysis (optimal at 3 months); immediate after hyaluronic acid.
  • Sessions: vary with fat, laxity and selected treatment.
  • Anaesthesia: generally unnecessary.
  • Social downtime: generally none.
  • Activities: immediate afterwards.
  • Price: 500 CHF per cryolipolysis session, 600 CHF per hyaluronic acid syringe (1 to 5 according to anatomy).
  • Sessions: 1 to 3 for cryolipolysis, 1 for hyaluronic acid.

Findings from clinical studies on double chin

  • A study published in Dermatologic Surgery shows significant submental fat reduction with satisfaction above 80% after one or two sessions and lasting neck-face contour improvement.
  • Data published in Lasers in Surgery and Medicine show that radiofrequency or other collagen-stimulating technologies improve submental firmness and results following fat reduction.
  • Publications in the Journal of Cosmetic Dermatology highlight improved chin-neck angle and perceived double chin through chin and jawline hyaluronic acid in underprojected chins, even without fat reduction.
  • Recommendations from the American Society for Dermatologic Surgery (ASDS) stress precise anatomical analysis of local fat, laxity and bone projection to combine appropriate techniques.

What causes a double
chin?

Causes include:

  • Genetics: predisposition to local fat regardless of weight.
  • Skin laxity creating a false double-chin impression.
  • Platysma (neck muscle) flaccidity.
  • Genetic or weight-related fat deposits.
  • Receding chin through insufficient bone projection.
  • Drooping or enlargement of the submandibular salivary gland.
  • Natural ageing reduces skin and muscle tone, contributing to sagging.
  • Posture and lifestyle can increase visibility.

Why do I have a double chin
although I am slim?

Slim people can have a double chin. Although weight is often associated, other causes may be responsible.

Does everyone have a
double chin?

No. It varies considerably with genetics, anatomy and lifestyle. Some are predisposed to submental fat. Diet and exercise also influence local subcutaneous fat.

How can a double chin be removed without surgery?

Method depends on cause.
Removing a double chin without surgery is possible; double chin liposuction is no longer the sole option.
Hyaluronic acid and cryolipolysis are used.

Removing a double chin naturally

Natural elimination is impossible, but daily habits can mildly improve it.

  • Balanced diet, particularly with excess weight.
  • Good hydration to reduce water retention.
  • Facial exercise: regular neck and chin massage can tone tissues and improve definition through lymphatic drainage.
  • Strategic make-up contouring creates jaw shadows to visually slim fullness.
  • Appropriate hyaluronic acid- or collagen-enriched cosmetics improve submental firmness and elasticity.

Double chin treatment without
surgery: hyaluronic acid

Hyaluronic acid suits a receding chin.
Dr Romano restores projection and injects strategic, anatomy-dependent jawline points for additional traction.
Immediate results last one year: less double chin, no added volume and better definition.
This belongs to the 7/9 Points Shape protocol.

What is the best treatment
for a double chin?
Cryolipolysis of the double chin

Cold-based fat reduction suits a fat-related double chin.
Consultation discusses treatment expectations.
Cryolipolysis reduces fat by 30-40%. Complete removal requires surgery, double chin liposuction.
The doctor confirms fat accumulation as the appropriate indication.
Contraindications and unsuitable indications, such as severe associated laxity requiring surgery, are excluded.

What happens during double chin cryolipolysis

The patient rests comfortably. Skin is cleaned and marked for precise placement of a dedicated applicator.
A protective wipe shields skin from cold; the applicator remains for 45 minutes.
Cold and suction sensations fade after minutes.
Gentle massage after removal prevents local inflammation.
Usual activities resume immediately.

Safety of double chin cryolipolysis

Cryolipolysis safely and effectively treats a double chin. Rare, minimal, temporary effects include redness, bruising and tingling.

How does
cryolipolysis work for a double
chin?

A dedicated applicator cools to -10°C, crystallising fat cells and triggering apoptosis (programmed death). Lymphatic elimination over 8 to 12 weeks does not change blood triglycerides or cholesterol.

How effective is
cryolipolysis work for a double
chin?

One session reduces fat by 25 to 40%, visible within weeks. One generally suffices, but numbers depend on severity.
Best results occur with minimal associated laxity.
Fat cells are permanently destroyed. Healthy habits prevent new deposits.

Before and after chin cryolipolysis results

Double chin cryolipolysis results develop gradually, visible at 4 to 6 weeks and final at 3-4 months.
Before/after photographs show reduced fullness, enhanced profile, visible neck-chin distinction, defined jawline and tightened skin.

How long results last

Results last for life unless new causes arise, such as substantial weight gain or salivary gland ptosis.

Double chin treatment prices in Geneva

Treatment depends on morphology, submental tissue (fat or laxity) and goals. Options include hyaluronic acid and cryolipolysis.
Hyaluronic acid costs 600 CHF per syringe. This includes assessment, product selection, aseptic injection and necessary follow-up. Numbers reflect chin-neck angle, jawline definition or receding chin; one to two suffice.
Cryolipolysis costs 500 CHF per session including consultation and generally 45 minutes to 1 hour of treatment. One to three sessions may be needed according to fat and response.
Consultation always provides a personalised quotation. Total varies with a single method or anatomically justified combination.

Patient feedback on double chin cryolipolysis

Feedback is mainly positive, with significant results and satisfactory experience.
Patients describe significantly reduced fullness and notably improved jawline.
They value non-invasive care allowing activities without convalescence.
It is praised for effective, simple, modern non-surgical reduction.

WHAT THE STUDIES SAY
01

In a study involving 60 people, cryolipolysis was used to reduce fat beneath the chin. Twelve weeks after the last session, ultrasound measurements showed an average reduction of 2 mm in fat thickness. Photographs confirmed improved definition of the area beneath the chin, and 83% of participants reported being satisfied. These results concern the device and settings used in this study.

02

In a randomised trial involving 200 adults, hyaluronic acid injections were used to correct a receding chin. At six months, chin projection had improved in 70% of treated patients, compared with none in the untreated group. An improvement persisted in 54.7% of patients at twelve months. By increasing chin projection, injections can better define the profile and make a double chin less apparent when a receding chin contributes to it. However, this latter effect was not directly assessed in the study.

03

A scientific review reports that radiofrequency can improve the firmness and elasticity of facial and neck skin. These results concern skin laxity, rather than the excess fat responsible for some double chins. A medical examination helps distinguish between these two causes and select an appropriate treatment.
