Am I candidate for Vanquish or liposuction? (photos)

I had an liposuction for my belly and love hands 5 years ago but now my dress size is 8 or 10 again as it was 5 years ago before the liposuction. I want to wear my 6 size dresses again. I am now wearing 8 size dresses. 36 year old, no child, my height is 155 cm/61 inches and weight is 58 kg/127 ibs. And I am not sure which is better for me. is another liposuction for belly and thighs necessary or will vanuquish be enough for dropping from 8 size to 6 size, just 4-5 cms?
