Kybella injections for the chin, are they really safe?

Thank you for your question about Kybella. Kybella is FDA approved for treating submental fullness, and as far as I am aware there have not been any links to cancer, autoimmune diseases, etc.  A few of the more severe risks with Kybella is nerve injury resulting in paralysis or uneven smile (all reported cases resolved with no permanent damage) or infection.  Other symptoms that are more common would be pain, bruising, swelling, and numbness.  Kybella is amazing and our patients have had great results.  Kybella works great at dissolving fat as well as offering mild skin tightening as well. 
To be sure, see two or more experienced, licensed and board-certified providers in your area for a complete evaluation to make sure you are a good candidate and that it is safe for you to have treatment. I hope this helps

Thank you for your question. As has already been mentioned, Kybella has been FDA approved and therefore been deemed safe for use. 

Yes, Kybella is FDA approved and safe. Both Kybella or neck liposuction are good options and will improve the double chin. It depends on your lifestyle and personality which would be better for you. 
Kybella is best for patients that:
1)  Do not want surgery 
2)  Are not surgical candidates 
3)  Not willing to wear a compression dressing around the face for 1 week 
4)  Patient-  The results of Kybella will take months
Kybella take 1-3 treatments every 6 weeks.  Patient will develop swelling and possible bruising after each injection that may last a few days.  The benefit of Kybella is each treatment is quick and completed in the office. However, some patients need more than one treatment to get desired results. 
Neck Liposuction is best for patients that:
1)  Want a single treatment 
2)  One recovery time-  Downtime for neck liposuction require wearing a wrap around face for 1 week. 3)  Less painful 
4)  Quicker results 
5)  Cost is a concern
Neck liposuction is a quick surgical procedure that can be complete while the patient is awake.  It cost around the same price a Kybella and can be less in patients with heavier necks.  The single recovery of neck liposuction may be a better option for some patients.
