Has Cheryl had the "ULTRA SMILE"?

When Cheryl Cole stepped out last week, for once it wasn't what she was wearing that had everyone talking.

Lip Fillers: The speculation, as she walked through a London airport, centred on whether her plumped up lips were the result of too much lip-gloss or something stronger. One cosmetic surgeon, 

Dr Ayham Al-Ayoubi, said, "Its takes between 24 and 48 hours for lips to go down after an injection, and ive seen this same look on hundreds of my patients after they've had lip fillers."

While Cheryl, 26, was quick to deny any work to her lips, she added that she wouldn't rule it out. "I haven't had surgery anywhere on my body," she said. "I certainly haven't had Anti-Wrinkle Injections, but who know in the future?"

Indeed, Grazia can exclusively reveal that such is the demand now among 20-somethings for anti-ageing procedures, dermatologists are developing treatments especially for younger women. Juvederm Ultra smile – an injectable lip filler – is launching in the uk this month and gives a very subtle plumping and shimmering "lip-gloss" effect. And new "lite" facial fillers are launching all the time for younger patients – these contain lower doses of active ingredients, meaning softer results.

But is this right? Last week, Grazia revealed the worrying trend among Hollywood's 20-something stars turning to plastic surgery to halt the ageing process. The hills star Heidi Montag recently underwent 10 procedures in one day, including an eyebrow lift and Anti-Wrinkle Injections. At only 23, Heidi admits to being "obsessed".
