Ask any dermatologist and they'll tell you that the most important product to stop signs of aging and wrinkles is sunscreen. And yet, most of us do not apply enough each day. La Roche-Posay, a French skincare brand now owned by L'oreal, wants to correct that with it's My Skin Track UV sensor.
This tiny sensor -- which looks a bit like a nazar -- attaches to your clothing or a necklace to measure your daily UV exposure. You hold the sensor up to your phone to transfer those measurements to the My Skin Track app to let you know when you've reached your maximum exposure.
When setting up the app, you'll fill out a questionnaire about your skin, and any skin concerns you have. For someone who's fair-skinned like me, the app will warn you when the UV index is high enough to cause skin damage and encourage you to apply sunscreen.
The app also tracks pollen and pollution in your environment and warns you when those factors might aggravate skin issues, such as eczema.
