I have been asked a number of times about treatment for double chin other than surgical intervention or liposuction and there are some available. Ultherapy, utilizing radio waves, was recently approved by the FDA and does a pretty good job.
Other Double Chin Treatments
Thermage, which has been around longer, uses a different wavelength and also works, but more slowly. The most recent FDA approval for this condition is called ATX101, which is an injection of an enzyme that destroys the fat and produces a little inflammation so that the skin might tighten. It takes a few treatments and is somewhat uncomfortable.
All of these methods are rather expensive with costs over $1000 and don’t forget if the skin is very loose it will not go up and give you a normal line. All these things should be considered and discussed with your dermatologist or plastic surgeon.
