Now you see it…now you don’t. Paint your kids’ faces (and other sensitive areas) in blue, white, or pink with this 100-percent natural mineral sunblock; the colors fade when it’s time to reapply. It is water-resistant, offers UVA/UVB protection, and has a nice, citrusy scent. Kiss My Face SPF 30 Sun Stick, $10.99 at Whole Foods Market.
