Emsculpt and Emsculpt Neo, Explained, Plus Reviews.

If someone told me there was a medical device that could build muscle and burn fat on my body's most stubbornly pudgy spots, I'd think they were nuts. But then I tried it for myself ... and boy, was I wrong. My butt became lifted and round in a way that I was never able to achieve, no matter how many squats or lunges I did, and I suddenly, magically, had abs! Who knew?

And what's the name of this aesthetic device? Emsculpt, and its super-powered next-gen little sister, Emsculpt Neo. Read on to find out what, exactly, they do and the Emsculpt results you can expect.

What Is Emsculpt — And How Does It Work?

"Emsculpt is a non-invasive body contouring treatment that builds muscle and sculpts the body," explains New York City-based dermatologist, Dendy Engelman, M.D., of the trailblazing technology packed into this FDA-cleared device. Launched in 2018, the machine is approved to use on those seemingly immune-to-exercise spots, including the buttocks, thighs, arms, and legs.

By using high-intensity focused electromagnetic technology (HIFEM), Emsculpt deeply and intensely stimulates the muscles, to "allow you to achieve fitness goals that otherwise remain out of reach," says author and cosmetic dermatologist, Paul Jarrod Frank, M.D. He adds that when used, it triggers 20,000 muscle contractions in the targeted area in just one 30-minute session, essentially tricking your body into thinking you just did 20,000 crunches or squats to tone and strengthen the area. (It's no surprise Drew Barrymore and her celeb friends are also fans of the treatment.)

Emsculpt is pain-free, but because of the severity of the contractions, you may feel slightly sore afterward, comparable to an intense workout, experts say. Throughout the treatment, there are five break periods with a tapping sound, which is actually "releasing the lactic acid in your muscles" so, no, you won't actually feel sore the next day like you would if you actually did 20,000 crunches, says Dr. Frank. And the best part? There aren't any known side effects of Emsculpt (like PAH, a known side effect of CoolSculpting), so you can try the treatment worry-free.

What About Emsculpt Neo?

Fast forward to late 2020 with the introduction of the Neo, an updated and slightly more powerful version of Emsculpt, which activates around 24,000 contractions versus Emsculpt's 20,000.

While it retains the OG device's HIFEM technology and still uses a handheld applicator, the Neo also throws in the addition of something called radiofrequency fat reduction. (Think of it as the equivalent of lifting weights plus a crazy intense SoulCycle class.) Here's how radiofrequency works: "The muscle temperature quickly rises by several degrees, which prepares muscles for exposure to stress," explains New York City plastic surgeon, David Shafer, M.D., comparing it to a workout warm-up. "Then, in less than four minutes, the temperature of the subcutaneous fat reaches levels that cause apoptosis, which is when the fat cells are permanently damaged and slowly removed from the body." Over the next two months, the damaged fat cells are naturally flushed out of the body, similar to the way Coolsculpting works.

A typical course of treatment is one session every week for four weeks, which cosmetic dermatologist Kenneth Mark, M.D., says "are the equivalent of 12 to 16 weeks of a high-intensity workout program." We know, it sounds too good to be true, but derms can't stop singing Neo's praises.
