Didn't wear compression garment after thigh liposuction. Now I have sagging skin. Would coolsculpting or a laser help? (Photo)

I had buttock implants last fall (2013) along with lipo to thighs. I got a life threatening infection that required hospitalization, etc.. I could no longer wear my compression garments because of risk of further infection to my wounds. Now, my thighs are so very flabby. I am not interested in a body lift. I have done radio frequency at least 20 sessions. Is there a laser that could possible help me? Or if I did coolscuplting and then wore a compression garment, would the skin reattach?
