After repeated Kybella treatments (like 4 or more treatments), does your body create scar tissue in the chin from needles?

The needles used to deliver Kybella's deoxycholic acid to melt submental fat are very thin and are unlikely to cause scar tissue. The reason no more than six sessions of Kybella are recommended are twofold: 1) Clinical studies didn't follow patients who had more than six sessions and so therefore cannot comment on the efficacy of going beyond that number of treatments; 2) Well-selected Kybella candidates should not need more than three or four treatments to achieve optimal results when dosed appropriately by someone who knows what they are doing.If you have a large degree of submental fat, it would probably be better treated with facial liposuction. If you want to avoid surgery, then several sessions of CoolSculpting could be a better choice than going beyond six Kybella treatments. Or, you could have a combination of CoolSculpting and Kybella treatements. Consulting a board-certified dermatologist that offers multiple modalities to reduce the double chin and letting him or her know what your concerns and desires are will help you choose the best treatment(s) for you.

The original studies on Kybella only went up to 6 treatments thus the limit. Most patients typically only need between 2-4 injections to see results. Schedule a consultation with a board certified plastic surgeon to be examined in person and see if you are a candidate. 

The amount of treatments recommended are based on results for improvement. It is unlikely that Kybella injections will cause a build up of scar tissue that will negatively impact your results. Keep in mind, a combination approach is needed to get the most improvement with non-invasive options like Kybella.  I recommend Kybella with thermage, ultherapy, exilis. VASER liposuction in combination with ThermiRF is the best alternative for contouring the chin. I recommend getting a formal evaluation with a cosmetic dermatologist. Best, Dr. Emer
