I'm a 58 year old female who had liposuction done on my knees 3 years ago. Too much fat was removed above knee leaving me with sagging skin, poor contours and a bulbous look to my knees. Then I had Ultherapy which made it look worse. It caused more fat loss on my thighs, worse contours and uneven pockets of fat around my knee. Is Kybella a good option for these pockets of fat surrounding and in front of knee cap? Should I consider skin tightening treatment at same time? Renuvion?
