So far, the main characters are still in pursuit of that. More importantly for them, they are in pursuit of some kind of stability.
As for the clients, each one is different. Some are there for cosmetic surgery to correct either a horrible accident or an error of nature (a gentlemen had a huge growth on his neck removed, about the size of a softball). And they come away looking, and feeling, like much more normal people.
In fact, not too many of the clients they show are what you would call 'routine' plastic surgeries. And those that are of the 'routine' kind, are glossed over and completely forgetable.
Your answer would be yes, but with a caveat.
Many of them come away happy, or at least satisfied with the results, but not all.
An example from Season 1, an extremely overweight woman wanted them to miraculously transform her into a sexy model type. The doctors inform her that before they even begin planning the surgery, she would need to lose some weight, change her lifestyle, etc., because she was not healthy enough to undergo such radical body alterations. They laid out the realities for her, as kindly as possible.
They've dealt with 1 plastic surgery 'junkie' already, and I believe there is another one in an upcoming episode.
A pair of identical twins wanted to look different(already gorgeous girls, in my opinion), and when the procedure was finally done, they shared a mental breakdown because they were not prepared for the shock of being different.
And there's plenty more....
As for the sex aspect?
One of the Doctors tried to go to Sexaholics Anonymous for a while, and it turned into an even greater mess for his life(it's always bad when 2 recovering sex addicts meet for drinks).
The Swan (on FOX), glamourized their contestants far more than anything on Nip/Tuck does. And those were real women subjecting themselves to the tortures of body manipulation in front of the world. And yes, I realize the same company runs both networks, but the same people didn't create both shows, so I feel justified in degrading one and not the other
