Growing numbers of young women are worried about lines in their neck caused by constantly staring down at their phone, according to a cosmetic doctor.
Celebrity aesthetician and star of Body Fixers, Dr Tijion Esho, said he's witnessed a spike in cases of 'tech neck' - deep lines on the throat caused by women frequently lowering their head to look at Instagram or Whatsapp on their smartphones.
He told the DailyMail he's administering fillers to neck lines on increasing numbers of women - and the female clients who come to him complaining of the problem are getting younger and younger.
Dr Esho said former TOWIE star Jess Wright is among those he's treated for 'tech neck', using a two-step treatment, spread out over a month, that involves injecting filler into key areas to plump out deep lines and stimulate collagen production.
A video of the Harley Street doctor performing the procedure on Charlotte Fisher reveals how it works.
Speaking to Femail about the trend, Dr Esho said: 'Lines in the neck used to be a concern for ageing patients over time.
'Now, as a new generation use more and more technology, the position we hold our necks in continuously can bring about the early onset of these lines known as 'tech neck'.
The doctor shared a video in which he was seen treating blogger Charlotte for the lines on her throat, explaining that she had had an initial 2ml of filler injected a month ago, ahead of this her second session.
Dr Esho, who said the effects of the treatment can last up to a year, can be seen drawing three lines along her neck before marking the points the filler should be injected at for maximum effect.
Dr Esho uses Profhilo rather than 'normal' filler, typically hyaluronic acid, which he says absorbed more easily and better improves the skin's quality and texture.
'You need two sessions- one at Day 0 and the second at day 30, and at both sessions the Profhilo is injected into specific points in the neck known as BAP points,' he said.
'These are points where in combination if injected with profhilo give the maximum effect of the benefits.'
Photos of Charlotte's neck before and after her first session show a reduction in the appearance of lines.
The increase in demand for 'neck filler' comes as new research from data analytics firm Nielson shows that the average smartphone users looks at their handset around 150 times a day.
Adults now spend almost half of their waking hours interacting with social media, watching television, or playing video games, according to its report - amounting to some 11 hours of screen time per day.
Young adults aged 18 to 34 reportedly spend the largest percentage of time using TV-connected and digital devices.
