A double chin, medically known as submental fullness, is the accumulation of excess fat beneath the chin in the submental region. This common aesthetic concern can result from weight gain, genetic predisposition, aging, or a combination of factors. Submental fat can be resistant to diet and exercise, and may affect facial profile and self-perception regardless of overall body weight.

At a Glance

  • A survey of 7,322 respondents found that approximately 73% were bothered by excess fat under the chin or neck[1]
  • Deoxycholic acid (Kybella) was FDA-approved in 2015 as the first injectable treatment for moderate to severe submental fullness[2]
  • Clinical trials demonstrated that 43% of Kybella-treated subjects had at least a 10% reduction in submental fat volume compared to 5% with placebo[2]
  • Submental fat accumulation can be influenced by genetics and may be resistant to reduction through diet and exercise alone
  • Even slight amounts of submental fat can be associated with negative self-perception and reduced confidence[1]

Affected Anatomy

  • Submental region
  • Platysma muscle
  • Cervical skin and subcutaneous tissue

What are the symptoms of Double Chin?

  • Visible fullness or convexity beneath the chin
  • Loss of jawline definition
  • Soft tissue laxity in the neck and chin area
  • Skin redundancy under the chin with aging
  • Increased submental volume that may not respond to weight loss

When should you seek care for Double Chin?

  • Submental fullness that persists despite weight management efforts
  • Desire to improve facial profile or jawline definition
  • Skin laxity or sagging in the neck and chin area
  • Concern about appearance affecting self-confidence or daily well-being

If any of these apply to you, don't hesitate to reach out for help.

What causes Double Chin?

Causes

  • Weight gain and increased body fat percentage
  • Genetic predisposition to submental fat accumulation
  • Age-related skin laxity and loss of tissue elasticity
  • Weakening of the platysma muscle over time

Risk Factors

  • Family history of submental fullness or double chin
  • Higher body mass index (BMI) or overall weight gain
  • Aging and associated loss of skin elasticity
  • Sedentary lifestyle
  • Poor posture, particularly forward head position

How It's Diagnosed

  • 1Visual assessment by a dermatologist or plastic surgeon
  • 2Physical examination to evaluate skin quality, fat distribution, and muscle tone
  • 3Use of validated clinical assessment scales such as the Clinician-Reported SMF Rating Scale
  • 4Evaluation of overall facial profile and neck anatomy

Frequently Asked Questions

A double chin, or submental fullness, is the accumulation of excess fat beneath the chin. It can result from weight gain, genetics, aging, or a combination of factors. Many people develop submental fat even at a healthy weight due to genetic predisposition.
Common causes include weight gain, genetic predisposition to fat storage in the submental area, age-related skin laxity, and weakening of the platysma muscle. Some people may develop submental fullness regardless of their overall body weight.
Consider consulting a dermatologist or plastic surgeon if submental fullness persists despite diet and exercise, or if it affects your self-confidence. A specialist can evaluate your skin quality, fat distribution, and overall facial anatomy to recommend appropriate treatment options.
Treatment options range from nonsurgical approaches such as injectable deoxycholic acid (Kybella), cryolipolysis, and radiofrequency skin tightening to surgical procedures including liposuction, chin augmentation, and neck lift surgery. The best approach depends on the amount of fat, skin quality, and individual goals.
Yes, several nonsurgical options are available. Injectable deoxycholic acid (Kybella) can reduce submental fat over multiple treatment sessions. Cryolipolysis uses controlled cooling to reduce fat cells. Radiofrequency and ultrasound treatments can help tighten skin in the chin and neck area.
While genetic predisposition cannot be prevented, maintaining a healthy weight through balanced nutrition and regular exercise may help reduce the likelihood of submental fat accumulation. Good posture and targeted neck exercises may also help maintain muscle tone in the area.
