New injection which zaps away double chin approved in the US
US regulators have approved an injection which could prevent the development of double chins.
The US drug regulator has approved an injection designed specifically to reduce unsightly double chins.
The drug, called Kybella, is injected into the fat below the chin and destroys the fat cells, according to the Food and Drug Administration (FDA).
But authorities also warned that Kybella can also kill skin cells if inadvertently injected into the skin, according to Bloomberg.
Kybella is a version of deoxycholic acid, a molecule that occurs naturally in the body to help destroy fat.
Patients may receive as many as 50 injections in a single treatment, the FDA said.
“It is important to remember that Kybella is only approved for the treatment of fat occurring below the chin, and it is not known if Kybella is safe or effective for treatment outside of this area,” Amy Egan, deputy director of the Office of Drug Evaluation III at the FDA, said in the statement.
Kythera’s shares jumped by almost 8 per cent on the back of the announcement.
However would-be patients are warned that serious side effects include nerve injury in the jaw that can cause an uneven smile or facial muscle weakness and trouble swallowing.
The most common side effects of Kybella include swelling, bruising, pain, numbness, redness and areas of hardness in the treatment area.
The treatment involves injecting a specially-formulated chemical – known as ATX-101 – into the skin to kill off fat cells known as “submental fat”.
While injectable drugs such as Botox and dermal fillers can plump and smooth the face, tackling a double chin has previously required more radical surgery.
