New beauty products show up on the shelves all the time -- who can keep track? While some can be instant classics that really change how we look (like these), many others aren't note-worthy enough for a re-purchase.

That's why we're so glad that there are these products -- the ones that stand the test of time and are always there to give us gorgeous skin and hair (and the ones we'd shed more than a few tears for if they ever discontinued them, are you listening beauty brands?!). Have you tried all these classic products? What are your beauty staples -- the products you can't live without?
