Eliminate Submental Fullness With Kybella And CoolSculpting

Fat, we all have it and many of us battle the under the chin bulge regardless of weight, or how healthy one's lifestyle is. Some can have a genetic predisposition to fat underneath the chin and find that no amount of exercise or dieting will slim down this stubborn fat. Once only surgical options such as liposuction were available to patients, but today REJUV AVE. offers two effective noninvasive treatment solutions from Allergan Aesthetics™ that can help eliminate submental fullness and can be used alone or together. 

How does each one work?

Although both slim the frustrating double-chin, the treatments are totally different in their method of fat-removal and their application.


CoolSculpting or cryolipolysis, is a procedure that uses cold temperatures to freeze fat cells and eliminate them via suction and cooling plates. The applicator is positioned on top of the treatment area, which is then cooled down until the cold temperatures numb the area (this takes only a couple of minutes). Once numbed, the fat cells beneath the surface continue to drop in temperature, bringing them to a point of irreversible damage (eventually, they are naturally expelled by the body). You may feel some coolness, suction and minor sensitivity.

Kybella—an injection of synthetic deoxycholic acid, which is a naturally occurring molecule in the body that helps metabolize fat —is FDA-approved for on-label treatment of submental fullness, aka a double chin. Kybella is injected in 20-30 spots under the chin, which are custom mapped before the treatment. This is done with a very tiny needle (20g), and is tolerated very well. To minimize any discomfort, we also apply a topical numbing cream and ice the area before administering. Once we have injected those 20-30 spots, Kybella will do its work.

Kybella and CoolSculpting both come with advantages and disadvantages when compared to one another that one should consider:

Application- Kybella is performed through a series of injections. So, individuals who don’t like needles may prefer CoolSculpting treatments. However, because Kybella is injected into small areas at a time, it can treat more precise or isolated areas of the chin. CoolSculpting, on the other hand, treats the whole chin area at once, rather than smaller targeted areas. 

Recovery- Following a Kybella injection you will have some swelling and fluid in the chin for a few days. You may also have bruising, tenderness and some numbness, which can last up to 6 weeks. With CoolSculpting, most people can resume routine activity immediately after. In some cases, minor redness or soreness may occur on the chin, but that typically will quickly subside. 

Results- After a fat cell has been broken down by Kybella, it has to be metabolized and processed by your body, so it will be a few weeks before you see the fat melt away. About 4-8 weeks is required for patients to see the full results from Kybella, and the injections can be repeated for an enhanced effect. It’s important to note that most patients need a minimum of 2-3 treatments for the full effect. It takes approximately 8-12 weeks for your body to break down and metabolize crystallized fats after a CoolSculpting submental treatment.  During that time, you'll see the fat beneath your chin shrink, and your jawline become more defined. Multiple sessions are also usually required for ideal results.

How do I know I am a candidate for CoolSculpting, Kybella or both? - Aside from making your decision based on the application or recovery method, the main deciding factor is what treatment plan is best after receiving your consultation. Everyone is a candidate for Kybella, as it's injection based, and we can target any pocket of fat, regardless of the size. CoolSculpting, you have to be a perfect candidate. This is because the application method is precise. Meaning, if your submental fullness is smaller in size, the applicator may not fit. Or may not fit with the shape of your jawline. In this case, Kybella would be recommended. If the applicator does fit, we'd recommend treating the bulk of your submental fat with CoolSculpting, then fine tune your results with Kybella.

Both CoolSculpting and Kybella can produce amazing results. So which is the better option? CoolSculpting, Kybella or a combination?
