Double Chin Eliminator Injection: What to Know
This drug company says an injection can get rid of your double chin.
— -- A new drug promises to get rid of double chins without surgery, and it's nearing federal approval.
The drug, an injectable substance that dissolves fat under the chin, was unanimously recommended for approval this week by a Food and Drug Administration advisory committee, but it's still awaiting final approval from the agency.
"Options at the moment for submental fat [double chins] are [to] cut it out or suck it out," said Dr. Susan Weinkle, a dermatologist in Florida who has been working with the drug in trials since 2007. "However, this is going to be a noninvasive in-the-office procedure that can be performed by your dermatologist and excellent results."
Here's what you need to know:
What is it?
It's a version of deoxycholic acid, "a naturally occurring molecule in the body that aids in the breakdown of dietary fat," according to its manufacturer, KYTHERA Biopharmaceuticals, based in Westlake Village, California. They're calling it ATX-101 right now.
How does it work?
"It disrupts the fat cell," said Dr. Derek Jones who gave Kythera's presentation to the FDA on Monday. "When it disappears, it disappears permanently."
Jones explained that the drug destroys the fat cell's membrane, causing it to burst. What remains of the fat cell is absorbed back into the body "via normal metabolic pathways," he said.
How much is needed?
Weinkle draws a grid of tiny dots beneath her patients' chin, she said, and injects .2 cubic centimeters into each dot.
"I actually mark the area that I see the max amount of fat," she said.
How long does it take?
It takes her five minutes to do the injections, she said, adding that she applies a little ice beforehand.
What's recovery like?
It takes two or three days to heal, Weinkle said. And no bandages are required.
How thoroughly has it been studied?
According to Kythera, it's been the subject of 19 clinical studies involving 2,600 patients.
Dr. William Stebbins, a dermatologist at Vanderbilt University Medical Center who was not involved in the studies, said he has seen Kythera's presentations at various dermatological meetings.
"I've been hearing about this for years and I'm actually really glad it's coming out," he said.
Who isn't a good candidate for it?
"This is not necessarily a silver bullet that will solve the problem for every patient, but it certainly is a good option for appropriate candidates," said Dr. Joshua Zeichner, a dermatology professor at the Mount Sinai Hospital in Manhattan. He has not been involved in the drug's development.
People with a lot of excess skin under their chin and neck aren't good candidates for this drug, he said.
"That's not a fat problem," he said. "It’s a skin problem."
Are there side effects?
Yes, side effects were bruising, swelling and temporary numbness, Stebbins said.
Will insurance cover it?
Insurance will not cover this procedure, and it's too soon to say how much it will cost, Zeichner said. In trials, patients received the injections once a month for up to six months before reaching the desired effect.
Why can't we use this in other areas of the body?
Jones said it would take significantly more product to remove fat from other areas of the body, and liposuction and other options would be more efficient.
