London: Wrinkles may be a sign of approaching middle age but younger women now have a reason to worry - the smartphone squint.
Many of them are developing premature wrinkles from staring at their smartphones, says London-based anti-ageing expert Jean-Louis Sebagh.
He said peering at a small screen causes facial strain, around and between the brows.
Sebagh, who treats celebrities like Cindy Crawford, said the phenomenon "can be seen on anyone who has and regularly checks a BlackBerry or iPhone".
"It`s easily rectified with the light use of Botox by an experienced doctor," said an Evening Standard report quoting the expert, according to the Daily Mail.
London beauty therapist Nichola Joss has also noticed the phenomenon among her customers.
Joss said: "I`ve noticed a huge difference over the past 18 months in my clients` faces - it`s the constant peering intently down at that mini screen. It`s the same with an iPhone."
Smartphone-related wrinkles are the latest condition that doctors attribute to overuse of technology. Others include `BlackBerry thumb` - a form of repetitive strain injury caused by excessive texting.
Another is `computer vision syndrome` - dry eyes caused by computer users failing to blink enough when staring at a screen for long periods.
