L'Oréal has teamed up with designer Yves Béhar to create a wearable UV sensor that tracks sun exposure, as a way of lowering the risk of skin cancer.
L'Oréal is launching the UV Sense at this year's Consumer Electronics Show (CES) in Las Vegas. It created the wearable device to allow people to take more notice of sun safety, and in turn reduce the risk of them contracting skin cancer.

It builds on a UV patch created by the company in 2016, which similarly tracked exposure to UV (or ultraviolet) radiation.
"The technology within UV Sense is groundbreaking, and has so much potential to impact the future of technology and wearables," said Guive Balooch, global vice president of L'Oréal's research and innovation technology department. "Armed with research and consumer insights from the original My UV Patch, we set out to create something that blends problem-solving technology with human-centred design, offering real-time data and longer wear in a discreet product that fits any lifestyle."
The small UV Sense device works without the need for a battery, so is relatively small in size ? measuring just two millimetres thick, and nine millimetres in diameter.
Users are instructed to place it on their thumbnail, as this is an area of the body that L'Oréal says receives "optimal sunlight".
Once attached, sensors deliver information about the wearer's UV exposure to an app using Near Field Communication (NFC) ? a wireless technology that works using ...
