Last year, Botox was the No. 1 most performed cosmetic procedure in the U.S., with 5 million treatments recorded, according to the American Society of Plastic Surgeons. There were a total of 11 million minimally invasive procedures done in 2009, the ASPS said.
But most 18-and-under pop tarts aren't looking to get Botox to erase wrinkles, since they don't have any yet. They want the injections for other reasons.
"I have teenagers [in Hollywood] who come in seeking Botox to change the shape of their face or the arc of the brow," said Stevens, whose practice is in Marina del Rey, near Los Angeles. "It can change the smile, making it softer and friendlier or more menacing. They're also coming in to ask about cheek implants, chin implants and neck liposuctions."
Nose jobs are common procedures in Hollywood too and usually happen before celebrities become household names, when they're in their teens.
"Unfortunately, the media and the makeover shows have made it look so darn easy, like going to get a hair cut," Stevens said. "So they just don't understand the gravity of plastic surgery."
It also can be blamed on the excessively nipped and tucked celebs idolized by young up-and-comers, like Lohan, Kim Kardashian and Heidi Montag, to name a few.
"A lot of girls in Hollywood have nose jobs before we know who they are," said Youn. "About 1 out of every 3 or 4 celebrities appear to have had their noses done, but most before they made it big."
The number of 13-19-year-olds who get plastic surgery is still relatively small -- only 2 percent of the total in 2009. But the uptick in teen stars going under the knife and getting cosmetic injections stems in part from an influx of media attention on plastic surgery and TV shows that glorify it, like 'Extreme Makeover.'
"The people who are popular right now have these overly exaggerated, Barbie-doll type bodies," said Youn. "These are the role models."
Stevens says he counsels teenstars to make sure they're aware of the risks and it's not their mothers or agents who are forcing them to get something done.
"I think the surgeon and the patient should be very circumspect about embarking on this alteration of their body or face at such a young age," he said. "It is my preference to postpone most of these procedures."
