2. Stickers that keep your sunscreen in check
These UV detection stickers turn purple when it's time to reapply sunscreen.
When it comes to sunscreen application, one of the biggest quandaries can be knowing when it’s time to reapply. Now thanks to SPOTMYUV Detection Stickers, you no longer have to guess. The purple stickers, which are water- and sweat-resistant, are worn on the body and turn clear when you apply sunscreen. As the day goes on, the stickers eventually turn back to purple to let you know it’s time to reapply. Stickers can be re-used for up to 12 hours, or a total of six sunscreen applications.
