Beauty shouldn’t be bad for you — and no one knows that better than Tarte. So the earth-loving brand joined forces with Lauren Conrad‘s charming blog, thebeautydepartment.com, to create a limited edition kit just in time for Earth Day. The $49 bag — available on tarte.com through the end of the month — includes four fabulous picks chosen by Amy Nadine, Conrad’s collaborator and makeup artist: LipSurgence lip tint in “Enchanted,” Amazonian clay smart mascara, Amazonian clay 12-hour blush in “Blissful” and “multiplEYE” lash-enhancing liquid liner. Tarte will donate 20 percent of proceeds from each sale to Wine to Water, an organization that provides clean drinking water to countries in need. It’s a beautiful way to give back!
