One of the best surgeries you can get to improve your attractiveness is actually jaw surgery and it's trendy in some parts of the world. Don't believe me? Google "jaw surgery blog" and look at some before and after photos. It produces some really hot people. Now let me tell you about the surgery. You need braces for about a year then surgery then eat from a straw for 1-2 months with solids 6 months later.
Very painful and very bloody.
You can do it only a few times due to scar tissue. Everyone loses some nerve function and it's not uncommon to be left with: numb chin/lower lip (drooling), numb palate/teeth (wooden, spongy feeling), facial paralysis, twitching muscles, TMJ problems, plates/screws that come loose years later or migrate, infected plates/implants even decades later, foreign body reactions, loss of teeth, shooting pains, and bone resorption. There's usually some relapse and it might only last 1-2 decades. These things happen even from the best surgeons in the world.
