Concern

Double Chin Treatment in Campbell

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]

Signs & symptoms

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

What causes Double Chin

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

How it's assessed

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

Maintaining a stable weight can help sustain treatment outcomes
Results may vary based on skin elasticity, age, and amount of submental fat

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. Targeted neck exercises and posture changes do not reduce or prevent submental fat. They may improve neck muscle tone, but they do not remove or change the underlying fat tissue that creates the appearance of a double chin.
