Be honest with yourself.
If you don't use a product or you haven't used it in the last year, toss it. Purge anything you wouldn't purchase again if you could do it over. Getting rid of excess clutter will make you feel good about yourself. "You're just using what you love and using it up," Morgenstern adds. If you only use part of a palette, consider depotting the shades you love into a magnetic palette like Z palette. Don't save 90 percent of the palette that you aren't using.
