Sunburn Alert UV monitoring body stickers

These sun smart stickers change color when you need to reapply sunscreen. Sunscreen is applied TO THE STICKER as you apply to the rest of your body. When the sticker turns blue, it's your reminder to reapply sunscreen as it has begun broken down and letting UV through. When you reapply sunscreen (again to the band and your skin) it will reset to white! They are waterproof and work with all types of sunscreen! Use a new one each day you go out in the sun! Perfect for vacations! New in retail box.
