The La Roche-Posay My Skin Track UV—reportedly the first battery-free wearable electronic to measure UV exposure—is available now at and select US Apple Store locations, according to L’Oreal USA in a media release.

My Skin Track UV was developed by L’Oréal’s Technology Incubator and unveiled at the 2018 Consumer Electronics Show. It features a precise sensor that is designed to measure individual UV levels and a companion app that tracks a wearer’s exposure to pollution, pollen, and humidity.

“Our research has long indicated the need for better consumer understanding of personal UV exposure,” says Guive Balooch, Global Vice President and Head of L’Oréal’s Technology Incubator, in the release. “We created this battery-free sensor to seamlessly integrate into the lives, and daily routines, of those using it. We hope the launch of this problem-solving technology makes it easier for people to make smart, sun-safe choices.”

The device measures both UVA and UVB rays, and provides instant status updates while storing up to 3 months of data. The battery-free sensor is activated by the sun and powered by the user’s smartphone using near-field communication.

My Skin Track UV relays stored data to its accompanying app through an easy single-touch function: users simply tap My Skin Track UV against their smartphone to update the app.

In addition to extensive UV data, the app—which integrates with Apple HealthKit—provides insights into humidity, pollen, and pollution levels. The discreet wearable sensor is 12mm wide and 6mm high, waterproof, and has a sturdy wire clip that can conveniently attach to clothing or accessories, the release continues.

My Skin Track UV is now available at and select Apple stores in the U.S. For more information, visit LaRoche-Posay.
