Are SunSignals® Sensors Waterproof?
Yes, of course they are! You want to be active in the water, so we created our sensors to be self adhesive and waterproof!
How Long Do the Sensors Last?
Because of the self adhesive formula we use, our sensors will stay on and continue to detect UVB rays for as long as you need it. Once it reaches the danger zone and you reapply sunsceen, be sure to use a fresh sensor to continue detection.
