Honestly it sounds like the same procedure to what they do when I donate blood with an apheresis machine. Only they put the plasma back in my arm where they got it from in the first place, rather into my chest.
People unhappy with their looks will do almost anything to correct it. This is just another procedure. Probably a lot better than implants, considering it is their own body. Soon, you'll be able to customize your body top to bottom, and then people will be really weird looking! Give it 50 years. .
