Certain fat deposits are determined by genetics, hormones, and body composition, and they don't respond to calorie deficits or extra cardio in the same way as other areas do. The lower abdomen, flanks, inner thighs, and under the chin are the most common examples.
Body contouring treatments exist specifically for this. They use energy-based technology to eliminate fat cells, build muscle definition, or firm skin in targeted areas without surgery or recovery time. But different treatments work in different ways, and the right one depends entirely on what you're trying to address.
Not all body contouring treatments work the same way. Some freeze fat cells, others use heat or injectables to destroy them, and some bypass fat entirely to work at the muscle level. Understanding what each one does makes it easier to figure out which is actually relevant to your concern.
Kybella is an injectable treatment using synthetic deoxycholic acid, a molecule the body produces naturally to break down fat. Injected beneath the chin, it permanently destroys the fat cells in that area. It is FDA-approved specifically for submental fat and is not used on other body areas.
Most patients need two to four sessions spaced about a month apart. Swelling after each session is common and can last several days. Results are gradual and permanent, as long as your weight stays stable, and specific to the chin and jawline.
It’s the only FDA-approved injectable specifically for submental fat.
TruSculpt uses radiofrequency energy to heat and permanently eliminate fat cells while simultaneously stimulating collagen production in the skin. That combination sets it apart from treatments that only reduce fat. Clinical studies show an average of 24% fat reduction after a single session, with results developing over 6 to 12 weeks as the body clears the treated cells.
Common treatment areas include the abdomen, flanks, inner thighs, and under the chin. Sessions take 15 to 60 minutes, depending on the area. There's no downtime, and many patients reach their goal in one to two sessions.
For patients with stubborn fat alongside mild skin laxity, the dual action makes truSculpt a more complete option than fat-only treatments.
Emsculpt uses high-intensity electromagnetic energy to trigger powerful muscle contractions that strengthen and define the treated area while also reducing fat. A clinical study published in Lasers in Surgery and Medicine used MRI to confirm simultaneous muscle growth and fat reduction in the abdomen following four sessions with the Emsculpt device, with results maintained at six months post-treatment.
It's the right fit for patients who want visible tone and definition in the abdomen, glutes, arms, or thighs, not just fat reduction. Sessions are 30 minutes with no downtime. Mild muscle soreness the day or two after treatment is normal and temporary. Most patients complete four sessions over two weeks for optimal results.
Emsculpt works at the muscle layer. No other treatment on this list does that.
For most patients, the decision comes down to what's actually bothering them. Stubborn fat in the abdomen or flanks points to truSculpt. When mild skin laxity is also part of the picture, truSculpt is the stronger choice since it addresses both in a single session.
Concern specifically under the chin? Kybella treats that area. The right fit depends on the size of the deposit and personal preference for injections versus a device.
Muscle tone and definition are different goals entirely, and Emsculpt is the only treatment here that works at that level. For patients who want fat reduction and definition in the same area, combining truSculpt and Emsculpt covers both.
We offer truSculpt and Emsculpt because together they cover the two concerns we hear most: stubborn fat and muscle definition. We've been caring for Marin County patients and the Bay Area since 2003, and every body contouring treatment plan is physician-supervised and built around your specific concerns.
For a full breakdown of how truSculpt and Emsculpt compare, see our guide to non-surgical body contouring.
For fat reduction treatments like truSculpt and Kybella, the eliminated fat cells don't return. Results last as long as the weight stays stable. Emsculpt builds muscle, and maintaining that definition over time requires staying active, the same way any fitness routine does.
It varies by treatment and by person. TruSculpt often produces meaningful results in one to two sessions. Kybella typically requires two to four. Emsculpt is done as a series of four sessions over two weeks. Your provider will outline a realistic plan during your consultation.
Yes. Combining truSculpt and Emsculpt is a common approach when the goal is both fat reduction and muscle definition in the same area. TruSculpt targets fat and skin firmness, while Emsculpt works on the muscle underneath.
No. None of these treatments requires downtime. Mild temporary effects are normal after each one: warmth or redness after truSculpt, muscle soreness after Emsculpt, swelling after Kybella. All resolve on their own.
Someone who is already close to their goal weight and wants to address specific areas that haven't responded to diet and exercise. These treatments aren't built for significant weight loss. The best results come when the goal is targeted refinement.
Most patients who come in for body contouring end up benefiting from more than one approach. Having truSculpt and Emsculpt available in the same practice means we can address fat, skin firmness, and muscle definition in a single, coordinated plan.
