London: A DIY laser wrinkle buster has been invited by reserachers at the UK’s University of Sunderland.

The device, which has been called Restorelite, looks like a computer mouse, and uses infra-red light, which is held over the area to be treated for a few minutes at least twice a day. Tests have shown the device has a 90 per cent success rate in zapping facial wrinkles and bags. It is hoped the device will go on sale next year at a price of about $80.

The invention was developed as a result of tests to treat cold sores. It was discovered that certain wavelengths of infra-red light kept white blood cells alive in adverse environmental conditions, speeding up the healing process.

To treat wrinkles the device is used twice a day for several minutes.
