But in addition to narcissism, the desire to have multiple plastic surgeries often ties in to borderline personality disorder, where sufferers have difficulty maintaining relationships, and body dysmorphic disorder, where a person becomes obsessed with a minor or imaginary flaw with their body.
"They have a real false sense of what they see in the mirror," said Seppinni.
"Many of them will tell you that when they look in the mirror, they won't look in the mirror unless it's from the neck down," she said, with the person only looking at the part of their body they need to.
"Even though, physically, they've changed [after surgery], they don't see the change, and that's why they continue to move forward with other surgery. They really have a distorted body image."
But the bigger issue, said Seppinni, is how narcissism and an addiction to drama that is common in reality television, affects viewers. It shows, she said, a lack of concern for the message to young women.
"That [a reality TV star] is a person where you have to ask what would you do if your life was productive? What would you replace the drama with?" said Seppinni.
Pamela Noon looks like a woman 20 years her junior. But it took Noon, who is in her early 60s, over 20 year to complete the transformation -- and she says it's not over.
Noon has had over 26 cosmetic operations on her face and body, as well as over 80 maintenance procedures, such as botox injections. Some of the procedures she has undergone include liposuction, multiple face lifts, brow lifts and rhinoplasty.
"I think [cosmetic surgery] is fairly addictive, because if you do something that turns your life around a little bit, particularly the way you look, you automatically feel better about yourself and are on to yourself every time you see something you should attend to. I'm definitely a work in progress," Noon told the New Zealand Weekend Herald in 2003.
But plastic surgery experts say there could be underlying psychological forces driving people who go to extremes with plastic surgery procedures.
Matarasso pointed out that people who feel they need to constantly perfect themselves physically through surgery could be showing signs of obsessive compulsive disorder, a need for perfection, or an inability to deal with aging.
"No matter what, they're never happy," Matarasso said. "But if [plastic surgery] is minimized to the point of going shopping, they are no longer looking at it as medicine. ... This is real-life surgery with health, welfare and safety complications. You can't take this lightly."
