Spending too long in the sun can damage your skin. By the time you have a painful sunburn, it’s too late; you’ve already overdone it. You can plan your day based on the UV forecast in a weather app, but forecasts are no guarantee of the actual conditions and can’t account for how long you’re exposed to harmful UV-A and UV-B rays.
The awkwardly-named My Skin Track UV sensor by La Roche-Posay is designed to pick up where forecasts leave off by measuring your actual exposure to harmful UV rays throughout the day without needing to be charged. It’s a remarkably small wearable sensor with a companion app that reports other environmental data too.
The My Skin Track UV sensor performed well in my testing, and I felt like it provided useful, actionable data about potentially harmful conditions that would be hard to judge without the device. The lack of charging and diminutive size makes the My Skin Track UV sensor easy to carry with you all day too. The trouble is, the My Skin Track UV is so small and light, and the clip is just slippery enough, that it’s easy to misplace or lose altogether, which I promptly did. Here’s what happened.
