Coolsculpting or Lipo on a petite 34 year old?

Hello. Great question. Thank you for your pictures. Based on your images, you can benefit from liposuction. Please schedule a consultation with a board certified plastic surgeon for a detailed surgical plan to achieve your desired results.

Thanks for the question. 
In this regard, I recommend you waist and back Liposculpture, getting better curves especially in the waist, improving your body contour.
Finally, I suggested take the fat we get and transfer to the buttocks and hips, to mold them and get better volume, contour and butt projection, is that we know as "Brazilian Butt Lift" (BBL).Kind regards
