Before starting treatment, one of Colair’s Nurse Injectors will examine the area under and around your chin to determine if Kybella® is right for you. Then, we will tailor your treatment to the amount of fat under the chin and your aesthetic goals. The injections take approximately 30 mins for each session. Now, keep in mind that this is not a one session process. In fact, it may take anywhere from two to six treatment sessions to get the results you want. The most common side effects have to do with redness, swelling, and discomfort at the injection site. We recommend getting the treatment done at least 4 weeks before an event, to allow swelling to subside and to begin to see results.
