This is exactly how long you should be keeping every beauty product you own.

Honestly ask yourself: Have you consistently added to your makeup collection for years, hardly throwing anything out?
Have you built your nail polish stash to include every color and shade under the sun, hardly using most of the colors in your arsenal?
If you've answered yes to any or all of these questions, it's time for a change. All the makeup you've had laying around for years can actually ruin your skin.
And those skin care products you've been stock piling are WREAKING HAVOC. Especially anything in a jar.
