Not trying to sound like your mom here, but if you're going to be in the sun, you need to wear sunscreen. The sun can do some serious damage to humans, which is why it's so important to protect yourself. But for sunscreen to do its job, you have to apply it and reapply it pretty consistently

Remembering to reapply is easier said than done though. If you're outside in the sun, chances are you're busy doing something that takes your attention away from sunscreen.

Well, L'Oréal seems to have solved that problem. In collaboration with La Roche-Posay, the companies created a wearable sensor that tracks UVA and UVB exposure levels, which was introduced at CES 2018. "UV Sense" is a tiny adhesive electronic sensor that syncs to an app to keep the wearer informed of when it's time to reapply sunscreen or get out of the sun completely.

Along with UV and UVB exposure, the app also informs the user of the current humidity level, pollen level, and air quality.

"We set out to create something that blends problem-solving technology with human-centered design to reach even more consumers who require additional information about their UV exposure," Guive Balooch, Global Vice President of L'Oréal's Technology Incubator, said in a press release.

The device comes with an adhesive back, which allows users to wear it for up to two weeks. At just 9 millimeters in diameter, it easily sticks to a thumbnail, a watch, or a shoelace—anything that is exposed to the sun. The sensor is activated by UV light, so it doesn't need batteries, and it's powered by the wearer's phone (compatible with iOS and Android).

UV Sense will launch in the U.S. this summer and around the world in 2019. Pricing is still being determined, but visit the website for updates.
