Know Before You Book: Everything To Know About Emsculpt, The Beloved Body-Contouring Treatment

There are no quick fixes when it comes to beauty and well-being. Whether you're looking to smooth fine lines, heal breakouts, or build lean muscle, long-term results stem from consistency, intentional effort, and, oftentimes, a great deal of patience. 

So when you hear that Emsculpt can immediately give you tight, toned abs in 30 minutes (while, gasp, lying down!), you might raise a brow—I know I did. 

Emsculpt is a noninvasive, FDA-cleared body-contouring treatment that stimulates your muscles using electromagnetic energy—high-intensity focused electromagnetic (HIFEM) technology, to be specific. Just one session ignites 20,000 muscle contractions within 30 minutes; that's 20,000 crunches or 20,000 squats, depending on where you place the paddles. 

The science was discovered by a physical therapy equipment manufacturer called BTL Industries. "They were approached by NASA to help devise a treatment that would help the astronauts return to function faster after they had been exposed to zero gravity," explains double board-certified facial plastic surgeon Jennifer Levine, M.D. After folks noticed its power to successfully and quickly build muscle, it quickly became a popular noninvasive treatment to tighten and tone. 

As I mentioned, one Emsculpt session is equivalent to around 20,000 muscle contractions. Imagine if you did that in the gym on your own—chances are you'd see some impressive changes to your lean muscle mass!   

"After four 30-minute sessions spaced one week apart, there is a 25% increase in muscle mass, [and] a 30% decrease in fat," notes Levine. 

While anyone who wants to benefit from more muscle is a solid candidate, both Levine and Engelman note it's especially helpful for new moms. "These treatments are particularly helpful for strengthening the core, so it is really beneficial to moms postpartum," Engelman adds. 

After four 30-minute sessions, you'll see a 19% improvement in diastasis recti2, Levine shares, which occurs when the stomach muscles separate during and after pregnancy. It's super common, affecting up to 60% of women3 during pregnancy or postpartum, and it usually results in a noticeable bulge in the middle of the belly. 

"What's great about Emsculpt and Emsculpt NEO is that it requires no pre- or post-treatment care," says Engelman. Levine does recommend drinking lots of water before and after to maximize the results, but other than that, you don't really have to prep for your Emsculpt treatment. 

"Each treatment is 30 minutes with zero downtime required," Engelman adds. Once you lay down on the treatment chair, your provider will place a paddle on the treated area—either your core, glutes, arms, calves, or thighs. 

"There will be a feeling of warmth, and the machine goes through cycles of contractions and then tapping to help release the lactic acid from the muscle so it can be restimulated," Levine explains. 

As for the comfort level? "You can expect to feel slight pressure as the machine is stimulating your muscles, but it really is a painless, and time-effective treatment," Engelman notes. "With Emsculpt NEO, you will also notice a heating sensation in the treated area that many patients compare to a hot stone massage." 

I'll be honest: I really did not know what to expect as I walked into Levine's NYC office. All I knew about Emsculpt is that a bunch of celebrities credit it for their toned, strong bodies. (And if it's good enough for the Kardashians, then it's certainly good enough for me.) 

After chatting with Levine and receiving a brief evaluation, she strapped me into the Emsculpt NEO machine. I swapped my jeans for a pair of stretchy scrub shorts. I kept my own shirt on but hiked it up so the paddle could lie across my entire core. 

The machine powered on, and I started at a medium setting. Again, I had no idea what to expect from the treatment, so when I felt the first contraction, my body did convulse a little (out of surprise or discomfort, I'm still not sure). I wouldn't describe the sensation as painful, but it's definitely not comfortable. 

I will say: It doesn't feel like you're just lounging in a chair doing nothing. My abs were certainly working! It almost felt like doing crunches—just, you know, lying down. 

Every few minutes, the contractions would stop, and the paddle would start tapping for several beats before resuming the treatment. Says Levine, those taps help the lactic acid release from my muscles, which prevents soreness. 

Once my 30 minutes were up, I was unhooked from the machine and stood to assess my results. I was surprised to notice some immediate changes! My stomach definitely appeared less bloated, and the sides of my body looked way more defined. 

My abs themselves were a little red from the radio-frequency, but already I could notice them looking more toned—and that was after just one session. The redness should dial down on its own, but Levine said I could apply a soothing cream on the area to reduce inflammation; she also recommends moisturizing the area regularly with a nourishing, firming cream or oil to enhance firmness (see my product picks below). 

Let's make one thing clear: Emsculpt should not replace a healthy lifestyle. You cannot ignore your diet and exercise plan and expect the body-contouring treatment to perform miracles. 

In fact, most people who see the best results already have a solid workout routine in place. "The ideal candidates are patients who are in good shape but are looking for some extra help to their existing workout regimen," notes Engelman. 

It's the same way we view supplements: No capsule or powder will replace healthy, whole foods, but you can consume additional nutrients and bioactives to help optimize your health. Think of Emsculpt and Emsculpt NEO as supplements to your exercise routine. And as I mentioned up top, it's great for new moms experiencing abdominal separation postpartum. 

In terms of who should steer clear of the treatment, both Levine and Engelman advise against it if you have a pacemaker or metal plates in the area. Engelman adds, "If you have metal implants in your body, such as an IUD, you should steer clear of both versions of Emsculpt. Women who are pregnant should avoid these treatments as well."
