Looking to lose a little belly fat? Monica Harris-Broome is anxious to find out how many inches she’s lost since having Liposonix three weeks ago.

“Oh my goodness, 4 inches,” she exclaimed while being measured around her waist.

“There wasn’t any surgery involved – no cutting, nothing invasive. That was the number one reason I was looking into it, and the second thing is there is no downtime,” Harris-Broome said.

Baumann Cosmetic and Research Institute on Miami Beach is one of only a handful of places in the country offering Liposonix since it was recently approved by the Food and Drug Administration.

On Tuesday Alexandra Briand was being treated with the new device, which uses high-intensity focused ultrasound to melt fat.

“So imagine when you put butter in the microwave and it gets all liquified. That’s what happens to the fat and your body absorbs it,” explained dermatologist Dr. Leslie Baumann.

Right now Liposonix is only approved for use in the abdomen and the flanks. That’s the area where you get love handles or muffin tops.

It took a while to get approval in the U.S. because of concerns over what happens to the liquified fat, which takes about eight weeks to get absorbed.

“Does it go into your bloodstream? Does it go to your heart and raise your cholesterol or raise your triglyceride levels? And it does not,” Baumann said.

The procedure takes about an hour, and it's not painless.

Briand winced several times while being treated.

“It’s not intolerable, it’s just uncomfortable,” she said.

This one-time treatment is not for people who have a lot of fat. Patients are told they can expect to lose one clothing size.

The cost ranges from $3,000 to $5,000.
