Whether it's a day at the beach or an afternoon on the trail, always remember to reapply your sunscreen. SPOTMYUV prompts you so you don't forget. Get a Free 2-Pack of SPOTMYUV UV Detection Stickers with Free Shipping for a limited time. Each time you cover your SPOTMYUV sticker with sunscreen, your SPOT will turn clear, showing you that you're protected from the sun's harmful UV rays. When your sunscreen wears off, SPOTMYUV turns purple again to remind you to reapply your sunscreen. Each SPOT lasts one day, 12 hours in outdoor sun.
