Why is Kybella not working on me? Have had 3 rounds of injections over 6 months.

Thank you for your question. It is difficult to comment without more history and an examination. Appropriate candidates for Kybella injections should certainly see improvement after 3 treatments. Kybella is indicated for treatment of excess subcutaneous fat in the central neck. Reasons for failure of treatment could be that the undesirable neck contour is not the result of subcutaneous fat accumulation but rather some other cause. Sometimes a double chin is caused by excess fat in a deeper tissue plane in the neck underneath the platysma muscle. Kybella should be injected superficial to the platysma and it is not safe to target this deeper fat compartment with these injections. An obtuse chin-neck angle may also result from excessive loose skin. Kybella works by dissolving fat and does not substantially tighten or reduce skin excess. It would be best for you to be under the care of a board certified surgeon who is an experienced injector and an expert in head and neck anatomy, aesthetics and the full spectrum of surgical and nonsurgical treatment options.

kybella dissolves fat in the area injected. It is pretty effective in reducing the fat burden of the area injected. Perhaps there is not as much fat in the area as thought. The fat could also be deep to the muscle; an area not affected by the medicine. Perhaps the injection is not reaching the target area (e.g. The needle isn't going deep enough). I would also recommend looking at your pictures before and after to make sure you haven't become used to your new look and have forgotten what it looked like before injection. 

If it did not work at all the first time the treatment should have been scrutinized for you specifically.  I have had very good results with one and two treatments.  Speak with your provider or go to a Board Certified Plastic Surgeon for an opinion regarding injectables and other facial rejuvenation techniques.
