Recycle: You should only keep concealer, lipstick, eye and lip liners, fragrances, powders, blushes, and shadows for a year and a half to two years. But there are still ways to practice sustainable beauty. One good way is to reusable compact cases for eyeshadows, blushes, and powders, and then just buy the refills when you run out. Stila makeup sells cheek and eye colors separate from their refillable compact case ($2). All of M.A.C.'s plastic packaged cosmetics are recyclable. Return six used items at any M.A.C. counter and receive a free lipstick in return.

Did you know that? Cargo's PlantLove lipsticks come in a compostable lipstick case made from corn. This revolutionary bio-plastic is not only made from a renewable resource, it's also greenhouse gas neutral, which helps us fight global warming. What's more, you can plant the box the lipstick comes in and it will grow wildflowers!
