A double chin can develop even when the rest of the body is slim and fit. Whether caused by genetics, age, or stubborn fat storage, under-chin fullness often lingers despite diet and exercise. At Manhattan Aesthetics, the most effective non-surgical approach to reducing and tightening this area combines two advanced technologies that target different aspects of submental fullness.
Why is Under-Chin Fat so Hard to Get Rid Of?
Fat under the chin, also known as submental fat, is notoriously resistant to traditional fat-loss methods. This is because:
- The area has a high concentration of fat cells influenced by genetics and hormones.
- The fat is often small in volume but strategically located, making it noticeable.
- With age, skin loses elasticity, which can contribute to a sagging appearance along with the fat.
Even those in excellent shape can notice that this pocket of fat doesn’t budge with cardio, clean eating, or weight training. That’s where targeted aesthetic treatments become invaluable.

Best Non-Surgical Treatment for Under-Chin Fat
For those ready to address under-chin volume without surgery or downtime, Manhattan Aesthetics recommends TruSculpt® ID followed by Sofwave™. This combination addresses both components of the double chin: the excess fat and the loose skin.
TruSculpt® ID uses radiofrequency energy to heat and permanently destroy fat cells. It’s a quick, comfortable treatment that targets fat under the chin without needles, incisions, or recovery time.
Sofwave™ uses ultrasound energy to stimulate collagen and elastin production in the skin, leading to firmer, tighter contours over time.
Together, these treatments deliver sculpted definition and smoother, more youthful skin beneath the jawline.
How Do TruSculpt® ID and Sofwave™ Work Together?
TruSculpt® ID and Sofwave™ are powerful on their own, but when paired, they create a comprehensive under-chin transformation:
Step One: TruSculpt® ID heats the submental fat layer using monopolar radiofrequency. The damaged fat cells are naturally eliminated from the body over several months. Most people notice a visible reduction in under-chin fullness after just one session.
Step Two: Sofwave™ is scheduled once initial fat reduction is underway or complete. It targets the mid-dermis with focused ultrasound, encouraging collagen regeneration. This helps to tighten and lift the skin for a smoother and more defined jawline.
When Will I See Results After Double Chin Treatment?
Results vary depending on the individual and their unique anatomy, but here’s a general timeline:
TruSculpt® ID: Noticeable fat reduction usually begins around 6 weeks after treatment, with optimal results appearing at the 12-week mark.
Sofwave™: Collagen remodeling takes time. Most start seeing skin-tightening effects around 4 to 6 weeks after treatment, with continued improvement over 3 months.
Am I a Good Candidate for Under-Chin Fat Treatment?
You may be a good candidate if you:
- Struggle with stubborn under-chin fullness
- Maintain a stable weight and a healthy lifestyle
- Want to avoid surgery or liposuction
- Have mild to moderate skin laxity under the chin
- Prefer a gradual, natural-looking transformation
A consultation at Manhattan Aesthetics can determine whether TruSculpt® ID, Sofwave™, or a combination of both is the right solution. These treatments can be customized to meet your unique aesthetic goals and deliver a more contoured jawline—without needles or downtime.
