The problem is the body will heal in unexpected ways. All the mega-stars have the best plastic surgeons in the world, don't think they don't. But that's the risk these idiots take by having these procedures done to stay young, fit and healthy and they know this. Look at people that get liposuction and they have weird spots or dents when the fat and fluid comes back. It's not the surgeons fault, it's how their clients bodies respond to everything; nip, tuck, break, etc.. Also blame it on the celebrities friends/entourage/clients who'll say they "look wonderful" no matter what so they don't lose their job or association. This is all commonplace in Hollyweird, everything is fake and full of lies.
Blood work is another BIG procedure. Ever ask yourself why the Rock, Tom Cruise, etc. always look young despite taking boatloads of drugs (and they ALL do)? How does Keith Richards and Mick Jagger live on and on despite all the excess? It's because they get new "young" blood filtered into them every month and their old toxic blood filtered out. Expensive procedure but very common among the rich and elite and works wonders.
Believe me, I know.
