An increasing number of women are developing peculiar signs of what an expert describes as the 'computer face'.
Michael Prager, a leading cosmetic surgeon, said professionals who worked long hours in front of a screen were ending up with saggy jowls, 'turkey neck' and deep-set wrinkles on their forehead and around their eyes.
The Botox specialist said that, of all his clientele, office workers were most likely to show premature signs of ageing.
'If you are one of the unfortunate people who frown or squint while they are concentrating at the screen then, over time, you will inevitably end up with frown lines,' the Daily Mail quoted Prager as saying.
"What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long.
"If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck," he said.
Prager, who has a practice near Harley Street in London, said he encourages his clients to put a mirror next to their computer so they can see if they are frowning at the screen.
'When people are stressed or thinking hard about something then they will often put on a "grumpy face" without even knowing what they are doing.
"When my clients put a mirror next to their desk they are often shocked by the angry, frowning face which stares back at them," said Prager.
Prager said there were several simple steps, which could stave off computer face such as regular screen breaks and stretching the neck muscles.
And, of course, there was always Botox.
He said that, after a couple of sessions of Botox, the habit of 'grumpy face' could be broken.
