L’Oréal releases wearable UV exposure tracker with NFC

Measuring your personal UV light exposure hasn’t historically been easy, as UV sensors aren’t built into typical wearables, smartphones, or other items people tend to carry around outside. That’s about to change thanks to L’Oréal, which today announced availability of My Skin Track UV — a wearable accessory that gathers personal UV exposure data to share with Android phones and iPhones, notably without requiring either Bluetooth or a battery. With its components inside a circular, shirt button-sized housing, My Skin Track UV will typically be clipped to a shirt in a position where it can measure both UVA and UVB rays.
