La Roche-Posay first launched its stretchable skin sensor to monitor UV exposure, My UV Patch, in 2016. Since the technology's debut, the La Roche-Posay brand has distributed more than one million patches to consumers in 37 countries free of charge to encourage sun safe behaviors.
Through consumer studies and feedback of My UV Patch users, L'Oréal learned that although users changed their behaviors, they wanted a smaller wearable with longer wear and real-time data. Building on the architecture of the original patch, UV Sense allows further monitoring of UV exposure, to show trends of exposure over time with instant updates.
UV Sense is the first battery-free wearable electronic sensor to measure individual UV exposure and can store up to three months of data. The wearable is less than two millimeters thick, nine millimeters in diameter and designed to be worn for up to two weeks on the thumbnail. The sensor can be reapplied to the nail with additional adhesives, which come in the packaging. By putting this technology on the thumbnail – which receives optimal sunlight – consumers can increase wear time from several days with My UV Patch to several weeks with UV Sense. .
"Beauty trends show that adoption of wearable nail art accessories is on the rise, with a more than 65% increase in nail art trends over the last five years. Our innovation taps into this growing trend, while illustrating our deep commitment to sun safe behavior and protection,” said Guive Balooch, global vice president of the group's Techology Incubator.
