What is EmSlim HIFEM?


Emsculpt is a nonsurgical body-sculpting procedure that builds muscle and burns fat by inducing muscle contractions with electromagnetic energy. It can tighten, tone, and strengthen the large muscle groups of the abdomen and buttocks as well as of smaller body areas, including the upper arms, thighs, and calves—creating more definition and reducing circumference.

So how does it work? Using high-intensity focused electromagnetic energy (HIFEM), the Emsculpt device delivers electromagnetic pulses to the muscle tissue and creates supramaximal muscle contractions, activating more muscle fibers than do the contractions you’d achieve through normal exercise. 

One 30-minute session produces nearly 20,000 muscle contractions. Contracting repeatedly without rest stresses the muscles, triggering rapid changes at the cellular level that make them grow bigger and stronger.

Pros and Cons 


  • Emsculpt is nonsurgical, it doesn’t require anesthesia, and there’s no downtime afterward.

  • While CoolSculpting and similar techniques simply remove fat, Emsculpt primarily tones muscles. It can be a good option for people who don’t have a lot of excess fat but want a more sculpted, defined physique and stronger muscles.

  • It’s a fat-reduction option for people who aren’t candidates for liposuction and nonsurgical body-contouring treatments because they don’t have enough body fat.

  • Having just four treatments yields visible results: RealSelf members who said it was “Worth It” saw an impressive increase in muscle tone. Some also noted a boost in strength that helped them achieve more during their workouts.


  • People with a few extra pounds to lose may not see as much of a change, because the fat can act as a barrier between the magnetic coil and the muscles, reducing the strength of the muscle contractions during treatment. 

  • While it reduces fat, it’s not a weight loss treatment. Even with positive results, you’re unlikely to see a change in weight, as evidenced in a 2019 study in the Journal of Aesthetic & Reconstructive Surgery.

  • A small percentage of RealSelf members who rated it “Not Worth It” said they were disappointed after not seeing dramatic results.

  • You’ll need multiple sessions in quick succession—four within a two-week period—so expect to stack your calendar with appointments.
