Clear Signs It's Time to Toss Your Makeup and Skin Care Products

Both liquids and powders are apt to change in consistency, though they do so in different ways. Liquids and creams tend to separate or become thicker/thinner. Powder products often get harder, drier and have less color payoff.

"When you see your powder products drying out, it's time to replace," says Moor. "Signs of that are that you can't pick up as much pigment on your brush or sponge and the application is not as smooth as it was previously."

If the product is relatively new and it has a hard "shell" or "coating" on top, this doesn't necessarily mean it's bad adds Patinkin.

"In the case of powder products like blush, bronzer and shadow, when you see a hard, speckled appearance on the surface and it's hard to get any color payoff, it means that oils from makeup brushes have transferred to your product," she explains. "In this case it's an easy fix. Simply use a dull knife to scrape the hardened bits away."

If the product seems super flaky or dry after doing this or has clearly dropped in quality, then move on.
