Many moms would love to be mistaken for their 20-something daughter's twin. But Janet Cunliffe went as far as Croatia and $14,700 to make sure it happened.
Just four hours of surgery on her eyes and nose, plus a couple of lip injections and a diet, and 50-year-old Janet says she's now regularly mistaken as the sister of her 27-year-old daughter, Jane Cunliffe, according to reporting by the Daily Mail.
"I envied Jane's crinkle-free eyes, full lips and luscious, long blonde hair," Janet told the Mail. "I was desperate to look more like my daughter, but knew no wrinkle creams could ever wind back the clock that far."
From foot binding, to piercings and heels, humans have always gone to great lengths to alter their appearance. But with the relatively low price of modern plastic surgery, people can, and do, go much further today.
One woman's quest for a bigger bosom hit the legal limit; at a gallon of silicone in each breast, any more would have broken Texas state law. Last fall a Korean woman's compulsion for silicone injections led her to try a homemade injection of cooking oil.
Experts say compulsive, severe and risky plastic surgery can belie an underlying psychological problem, but not always.
The following is a list of notable cosmetic procedures compiled by ABCNews.com, as well as reflection by reputable plastic surgeons and doctors on what the medical profession should do about patients seeking extreme plastic surgery.
Cunliffe was not the first woman to ever ask for another person's face. So-called "octomom" Nadya Sulemen reportedly wanted to look like actress Angelina Jolie.
But plastic surgeons say Cunliffe's request to look like a family member is very rare.
"Certainly it's not the usual day in my office," said Dr. Malcolm Roth, director of plastic surgery at Maimonides Medical Center in Brooklyn, N.Y.
"To say, 'you're 50 years old, I'm going to make you 20 years old' -- that's not reasonable," said Roth, who is also the vice president of the American Society of Plastic Surgeons.
However, Roth said in Cunliffe's case, the request to make her look like her daughter might be more reasonable than a request like Sulemen's to look like a total stranger.
"It's her daughter -- they have the same genes, probably a lot of the same facial structure and architecture," he said.
But just because something is possible doesn't mean Roth will always comply with a patient's request.
"Over half of the patients who come into my office for plastic surgery I would not operate on," said Roth, who listed both medical concerns and concern over the idealism of his patients as reasons he'd not operate.
Cunliffe's case might be a drastic request, but Roth said he'd be more wary of her choice to try medical tourism.
"We're seeing, unfortunately, a lot of people who are looking for good deals, going to medical tourism and then they come back with problems that cost them more than they would have paid in the first place," he said.
It would be hard to miss Sheyla Hershey if she were walking down the street. She has record-setting breasts after years of plastic surgery.
