Stickers that remind you when to reapply sunscreen & seek shade?! You heard right.
Simply apply sunscreen to skin and the stickers to activate. When the sticker begins to turn to a lighter color, this is your reminder to reapply sunscreen.
How is this possible?! There are special patented photo-chromic dyes imbedded in the stickers that change colors when exposed to the UV radiation of the sun. This is the same damaging UV radiation for which we use sunscreen to protect our skin when we go out into the sun.
