Out With The Old, In With The New

Style.com just posted guidelines for the shelf-life of cosmetics that I think is extremely helpful. I've been known to keep foundation and sponges for waaaay too long. Seriously, though, I think it's fine if you keep your items longer than posted below, but that's just me.

Powders and shadows: Two years
Cream shadows: 12-18 months
Foundation: One year
Lipstick/lipliner: One year
Mascara/eyeliner: Three months
Makeup brushes: Clean weekly using a mild detergent
Makeup sponges: Replace weekly, or when sponge becomes completely covered
