Want the tan but sunburn easily? A simple wristband might be your solution.
"It works when UV rays react to chemicals inside the material which causes them to change from a yellow to a pink colour," the BBC explains.
The pink indicates that you are at risk of getting a sunburn and therefore damaging your skin.
For the past couple of years, researchers in Scotland have spent more than £50,000 developing the band. It is now the first of its kind in the UK and will hit the market in a couple of months.
