Get rid of double chin concerns are one of the most common reasons patients visit Nusbaum Medical Centers for a body-contouring consultation. Submental fullness, the medical term for a double chin, can result from genetics, aging, weight, or skin laxity — and today there are several effective non-surgical options that address it without an incision or significant downtime.

What Actually Causes a Double Chin
A double chin, or submental fullness, isn't always about body weight. Genetics play a significant role in how much fat accumulates under the chin regardless of overall body composition, and aging naturally reduces skin elasticity in the neck and jaw area, which can create the appearance of fullness even in otherwise fit individuals. Posture and muscle tone in the neck can also contribute. Understanding the underlying cause is the first step in choosing the right non-surgical treatment.
Because multiple factors can contribute at once, many patients are surprised to learn that diet and exercise alone haven't resolved the issue, even after significant weight loss elsewhere in the body — this is a common and completely normal experience, not a sign that something is being done wrong.
The submental area is also one of the first places many people notice early signs of aging, since the skin here is thin and the underlying muscle (the platysma) can begin to loosen earlier than skin in other facial areas, contributing further to the appearance of fullness.
Aging, sun damage, and long-term weight fluctuation can all compound these factors over time, which is part of why patients in their 40s and beyond often notice a more pronounced double chin than they had in earlier decades, even without significant weight change.
CoolSculpting for Submental Fat
CoolSculpting uses controlled cooling to freeze and permanently destroy fat cells under the chin, which the body then naturally eliminates over several weeks. It's a well-established, FDA-cleared option specifically for submental fat, with no incisions and no downtime. Most patients need one to two sessions, spaced weeks apart, to achieve a visibly slimmer profile.
The treatment itself takes about 35 minutes for the chin area, and most patients describe the sensation as an intense cold that fades to numbness within the first several minutes, making the remainder of the session comfortable.
Because there's no downtime, most patients return directly to work or errands after their appointment, with any mild swelling or firmness typically resolving within a few weeks as the treated fat cells are gradually cleared.
Because the applicator is specifically designed for the submental area, treatment can be precisely contoured to your unique jawline shape, helping avoid an unnatural or overly hollowed appearance in the final result.
Injectable Fat-Dissolving Treatments
Injectable deoxycholic acid treatments work by directly breaking down fat cell membranes in the treated area, with the body clearing the resulting debris naturally over the following weeks. This option typically requires a series of sessions spaced about a month apart, with visible improvement building gradually. It's a good option for patients with a moderate, well-defined pocket of submental fat and no significant skin laxity.
Temporary swelling, numbness, or firmness in the treated area is common in the days following injectable treatment and gradually resolves as the body clears the affected fat cells over the following weeks.
When Skin Laxity, Not Just Fat, Is the Issue
For patients whose double-chin appearance comes primarily from loose skin rather than excess fat, fat-reduction treatments alone may not fully address the concern. In these cases, a skin-tightening treatment like Morpheus8, which combines microneedling with radiofrequency energy, can stimulate collagen production and visibly tighten the jawline and neck area. Some patients benefit from combining fat reduction with skin tightening for a more complete result.
A numbing agent is typically applied before injectable or skin-tightening treatments to keep the session comfortable, and most patients describe the sensation afterward as mild tightness or tingling rather than significant pain.
Because skin-tightening results build gradually over several months as new collagen forms, patience is an important part of the process, and most patients see their best results appearing well after the initial treatment series is complete.
Combining Treatments for the Best Results
- CoolSculpting or injectables to reduce fat volume
- Morpheus8 or similar treatments to tighten remaining skin
- Dermal filler along the jawline to enhance definition in select cases
- A consistent skincare routine to support skin health throughout treatment
A layered approach, chosen based on your specific anatomy, often produces a more refined result than any single treatment alone. Your provider can sequence these treatments over several months for a coordinated, natural-looking outcome.
Posture and neck-strengthening exercises are sometimes recommended as a complementary habit alongside these treatments, since improved posture can subtly enhance jawline definition on its own and support the results of any in-office treatment you pursue.
Maintenance is also part of a thoughtful long-term plan — fat-reduction results are generally permanent for the treated cells, but skin-tightening benefits and filler placement may need periodic refreshing over the years as natural aging continues.
How to Choose the Right Treatment for You
The best way to determine the right approach is an in-person evaluation, since fat volume, skin quality, and jawline anatomy vary significantly from patient to patient. The American Society of Plastic Surgeons notes that non-surgical submental fat reduction has become one of the most popular minimally invasive treatments in recent years, reflecting both its effectiveness and appeal for patients who want results without surgery. Our Cedar Knolls team offers a personalized consultation for patients throughout Morristown, Livingston, and all of New Jersey. Explore our body sculpting and Aveli treatment options as well.
Because the neck and jawline are such a visible, expressive part of the face, we take extra care to ensure any treatment plan looks natural and proportionate rather than overdone, which is a central part of every consultation for this area.
We're proud to offer patients throughout Cedar Knolls and New Jersey a full range of non-surgical options under one roof, so your treatment plan can be built around your specific anatomy rather than limited to whatever single technology a smaller practice happens to offer.
