When appropriately used, dermal fillers and Botox can turn back the clock and get rid of unsightly wrinkles, but clearly skin expert Dr Ben Behnam is in no mood to sing its praises, after he recently launched a scathing attack on France’s First Lady Carla Bruni for her over-indulgence in the treatment.

‘She has had way too much done’ Dr Behnam told The Daily Mail, ‘That’s why she has the surprised look on her face and she looks like a chipmunk.’ But the LA dermatologist didn’t stop there, he went on to say that the 44-year-old appeared to have had a lateral brow lift and dermal fillers injected into her cheeks to reduce wrinkles. ‘The tiny shadows you can just see beneath her nose were probably caused by injectable fillers to get rid of nose-to-mouth lines.’ He said.

The former supermodel is famed for her good looks and flawless skin, but according to Dr Behnam she is in danger of falling into the trap of looking like every other Botox-ed celebrity. ‘A lot of celebrities these days look the same’, he said, before giving Carla and her famous friends some advice on how to maintain a smooth complexion, without overdoing it. ‘What they should do is just do a little bit so it just makes them look like a younger version of themselves, rather than a 50-year-old trying to look 25.’
