Locate the concern
Look at the jawline and neck both at rest and in profile. Loose skin, deeper folds, and fullness below the chin can look similar in a photograph but call for different discussions. The clinic presents XERF as a lifting and tightening service. Ask whether your specific issue is one that radiofrequency treatment can plausibly address.
Ask how much change to expect
Request an explanation of the expected area and degree of change, not just a statement that the jawline will be lifted. Ask how many visits might be needed before a fair assessment and what a modest result would look like. If comparison photographs are used, confirm that head angle and lighting match, since a small change in posture can alter the neck line.
Plan around alternatives
Marie Jé also lists Radiesse contouring and fat-reduction injections. These are not interchangeable with XERF: contouring addresses shape with an injectable, and fat treatment raises separate product and safety questions. Have the clinician explain why their proposed option matches the cause of your concern and what each alternative would leave unchanged.
Questions and answers
Can XERF remove under-chin fat?
The clinic describes it as a lifting service. Ask for an assessment of the fullness before treating it as skin laxity.
