London, (Agencies): Younger women now have a reason to get worried because the smartphone squint is capable of causing pre mature wrinkles in them.

According to a London-based anti-ageing expert Jean-Louis Sebagh, “many of them are developing premature wrinkles from staring at their smartphones.”

He said looking 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".

Reportedly it can be easily rectified with the light use of Botox by an experienced doctor.

Beauty therapist in London, 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."

Doctors attribute overuse of technology to be the reason for smartphone-related wrinkles. Others ill effect can include 'BlackBerry thumb' - a form of repetitive strain injury caused by excessive texting.
