A double chin can be one of the most stubborn concerns to address without professional treatment. While diet and exercise can help improve overall body shape, some people may still struggle with submental fat that lingers beneath the chin.
In this blog, we’ll explain what can cause excess fat under the chin, what submental liposuction is and how it works, and which other chin fat removal treatment options may be worth considering based on your anatomy, skin quality, and goals.
Common Causes of Excess Fat Under the Chin

If you’re wondering why your double chin seemingly won’t go away despite eating well, staying active, or maintaining a stable weight, it’s not because you’re not doing enough. There are multiple factors that can contribute to fullness under the chin, and some of them have very little to do with lifestyle. A few common causes include:
- Genetics: For many people, submental fat is simply something they are more likely to develop because of genetics. If double chin fullness runs in your family, your body may naturally store more fat beneath the chin, even if the rest of your body is relatively slim. This is one reason some people notice under-chin fullness at a younger age or continue to struggle with it after weight loss.
- Weight Changes: Weight gain can increase fat throughout the body, including the area under the chin. However, this does not mean a double chin is always caused by being overweight. Some people lose weight and still notice fullness beneath the chin because that area can be resistant to change. When fat is concentrated in the submental area, targeted chin fat removal treatment may be more effective than relying on general weight loss alone.
- Aging: As we age, the skin and soft tissues around the jawline and neck begin to change. Skin can become looser, collagen levels decline, and the natural support under the chin may weaken. This can make submental fat look more noticeable or create the appearance of heaviness under the chin, even if the amount of fat has not changed dramatically.
- Facial Anatomy: Your bone structure and facial proportions can also affect how the chin and neck area looks. A smaller chin, weaker jawline, or shorter chin-to-neck angle can make fullness under the chin appear more prominent. In these cases, the issue may not be fat alone. A consultation can help determine whether submental liposuction, skin tightening, or another chin contouring procedure is the better fit.
- Skin Laxity: Loose skin can sometimes be mistaken for excess fat. If the skin under the chin has lost firmness, the area may look soft or undefined even without a large amount of fat present. Submental liposuction can remove fat, but it is not designed to correct significant sagging on its own. Patients with more advanced laxity may need a different treatment approach, such as skin tightening or a neck lift.
What Is Submental Liposuction and How Does It Work?

Submental liposuction is a targeted procedure that removes excess fat from beneath the chin. This area is known as the submental area, which is why the treatment is often called submental liposuction. It may also be referred to as chin liposuction or neck liposuction when the treatment helps improve the upper neck and jawline contour.
At Derma Laser Center NJ, double chin lipo treatment is planned around your natural chin, jawline, and neck shape. Before treatment, the provider looks at whether the fullness is caused by fat, loose skin, facial structure, or a mix of factors.
The procedure uses small entry points and a thin cannula to remove unwanted fat under the chin. SmartLipo may also be used to help liquefy the fat before removal, while Derma Laser Center’s TOPAL™ technique combines tumescent anesthesia, power-assisted liposuction, and laser liposuction for more precise contouring.
For the right candidate, this can reduce stubborn double chin fat, sharpen the jawline, and create a smoother chin-to-neck profile with minimal visible scarring.
Other Submental Fat Reduction Options for Double Chin Fat
For patients who want an option other than double chin liposuction, there are several treatments that may help improve fullness under the chin. The right choice depends on what is causing the concern.
Some patients have mild to moderate fat, while others may be dealing with loose skin, reduced skin firmness, or more noticeable neck sagging. Here are some double chin contouring procedures that may be worth discussing during a consultation:
Fat-Dissolving Injections

Fat-dissolving injections are a non-surgical option for patients with mild to moderate submental fat. The treatment uses injectable medication to gradually break down fat cells beneath the chin, allowing the body to process them over time.
This option may appeal to patients who are not ready for liposuction or prefer a treatment that does not involve incisions. However, results are gradual, and multiple sessions may be needed to achieve the desired improvement. It is also important to note that injections are best suited for fat reduction, not loose skin or more advanced neck laxity.
Skin Tightening Treatments

Skin tightening treatments may be recommended when the main concern is mild looseness under the chin rather than excess fat alone. These treatments are designed to help firm the skin and improve the appearance of softness in the chin and neck area.
They can be a good option for patients who have early skin laxity or want subtle improvement without surgery. However, skin tightening treatments do not remove fat the same way liposuction does. If the double chin is caused mainly by a pocket of stubborn fat, skin tightening alone may not create enough contour.
Neck Lift

A neck lift is a surgical option for patients with more advanced loose skin, sagging, or visible neck bands. This may be recommended when the issue is not just double chin fat but also skin and muscle laxity that affects the entire neck profile.
Compared with non-surgical treatments, a neck lift is more involved and usually requires more downtime. However, it may provide a more complete improvement for patients whose concerns cannot be corrected with fat reduction alone. For this reason, a consultation is important to determine whether the problem is mostly fat, skin, or a combination of both.
Schedule a Consultation to Learn If a Double Chin Liposuction Procedure Is Right for You
When a double chin does not improve with diet, exercise, or lifestyle changes, the cause may be more than general weight gain. A personalized consultation can help identify whether the fullness comes from submental fat, loose skin, facial anatomy, or a combination of concerns.
At Derma Laser Center NJ, your treatment plan is based on your anatomy and your goals. If you are curious about what this type of contouring can look like, you can also view our neck liposuction before and after pictures to see examples of real patient results.
