Today on Channel KENS5 in San Antonio, Sonterra Laser Med Spa demonstrated Kybella. This recently FDA approved treatment is helping patients who have a stubborn double chin or a saggy neck that just won't go away, even with diet or exercise. After numbing her neck, Sonterra Laser Med spa's medical director Dr. Sanjiv Kumar pointed out dots on the patient's neck. Those mapped out exactly where the injections will go. The injection is a solution that will yield a slimmer contoured jaw line within four weeks. "You're basically injecting a naturally occurring substance that you have in your body to help you dissolve fat," he said. In fact, Kybella is similar to the body's natural deoxycholic acid produced in the stomach. Now, it can be inserted to dissolve fat and can have a lifetime effect. "That particular fat patch should be gone permanently, because you've actually killed those cells," said Kumar. Some patients may experience common side effects of temporary bruising and swelling. The FDA's website reports that serious side effects can include nerve injury in the jaw that can cause an uneven smile, facial muscle weakness and trouble swallowing. Those are not common side effects. Kybella treatments at Sonterra Laser Med Spa start at $1,500 dollars.
