Ohh I just saw this thread! I'm finding that because my best friend has been a MAC fan since like 2000 that she has a ton of old goodies that I love going through. Most recently, she gave me some old lipsticks, including Isabella Blow. I think that's 2005? She has a few of the screw pot style eyeshadows, in which I inherited Riot from her. Shrugs, I thought bacteria isn't likely to live on the powder products right? I did sanitize the lipsticks by dipping and wiping about 3x in rubbing alcohol though, and they still smell vanilla...ish. I don't think I'd throw away my make up for a long time! I take it out sometimes and sanitize products I haven't used in awhile, anyone else do this?
