Would I be a better candidate for CoolSculpting or Ultrasonic Cavitation?

Without photos it is not possible for me to give you a thought on your question. Make sure you seek a consult with a great practice with an experienced Cool Sculpting Provider. Most places don't measure before and after for cool sculpting as a measure for improvement, it's based on having pinchable tissue that the applicator can improve. Usually small areas of stubborn fat look great after cool sculpting so it all depends on how you look and what area they can treat. Good Luck. 

Than you for your question. An in person assessment is needed  to determine if you are a good candidate. Please consult with a board certified plastic surgery.Regards,

I agree that you need to be seen and examined however I think in general I have seen better results with cryolipolysis machines that US machines. that means Coolsculpting in my experience. Best Dr. Gharagozlou

Between the options you had listed , coolsculpting removes more subcutaneous fat (20-25% after one session) verses ultrasound (11%... or 32% after 3 sessions) Coolsculpting is a more comfortable and virtually a painless treatment.  At 118 lbs and 5'3, I would not expect to lose 3 inches. Even liposuction would not likely reduce 3 inches from your waist, as this is seen more with larger individuals. It's best you seek consultation to see if any non invasive treatment can render your treatment goals. 

Hello and thank you for your question. Coolsculpting is a great treatment to get rid of stubborn fat that is not going away with diet or exercise. There needs to be at least 2 inches of "pinchable" fat in the area you want treated. My recommendation would be to seek a consultation in a practice with a board certified physician. Hope this helps, Dr. S.
