L'Oréal's La Roche-Posay brand has unveiled UV Sense, the first battery-free wearable electronic UV sensor at the 2018 Consumer Electronics Show in Las Vegas.

In 2016, La Roche-Posay launched the first-ever stretchable skin sensor to monitor UV exposure, My UV Patch. Since the technology’s debut more than one million patches have been distributed to consumers in 37 countries free of charge. 

Company consumer studies show that My UV Patch had a positive impact on the sun safety behaviours of consumers, with 34% applying sunscreen more often and 37% trying to stay in the shade more frequently.

The new UV Sense is smaller, and offers longer wear and real-time data, says the company, and can store up to three months of data as well as show trends of exposure over time with instant updates. It is less than 2mm thick, 9mm in diameter and designed to be worn on the thumbnail.

By putting this technology on the thumbnail – an area which receives optimal sunlight - consumers can increase wear time from several days with My UV Patch to several weeks with UV Sense. 

UV Sense has an accompanying mobile app, available on both iOS and Android, which translates and transfers data from the sensor using Near Field Communication (NFC) enabled technology. The app delivers consumer-friendly information detailing when the wearer should be mindful of UV exposure, plus tips of when to spend time in the shade or reapply sunscreen.

“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 Incubator. 

For the design of UV Sense, L’Oréal has collaborated with world-renowned designer Yves Behar. “Design and technology are inextricably linked, and as products become more personalized to individuals, both elements are integral to providing people with seamless experiences,” said Behar.

UV Sense will launch in the UK in 2019.
