Is it time for more drastic plastic, Anne?

But after three years, perhaps the warranty is about to run out.

As she left a London hairdressing salon at the weekend, Anne Robinson, 62, was looking a little less polished than usual.

Eagle-eyed observers suggested her surgically smoothed complexion could be starting to feel its age again.

There was a hint of sagging skin under her chin, along with the pitter patter of tiny crow's feet.

According to experts, these are classic signs of the limitations of cosmetic surgery.

"She doesn't look as good as she used to when she first had the facelift," said Apostolos Gaitanis, a Harley Street cosmetic surgeon.

"I think at this stage she does not need another facelift but in the next two or three years she will. She could benefit from Botox around her eyes which will improve the appearance. Her eyebrows are also slightly low.

"Also she could have lost weight in the last few years which could account for the loose skin around her chin. I would also recommend for her to use fillers to improve the appearance of her top lip."

The presenter of BBC2's The Weakest Link quiz show had her £9,000 facelift in 2004.

At the time, she declared: "I think anything that allows women to feel better about themselves is worth the money.

"I did look like a car crash for a couple of weeks. But it was soon over and I feel much better for it.

"It wasn't a fortune - it cost me the price of one and a half Hermes handbag."
