But don’t fret: We consulted makeup artists on how to use these sponges for smooth, velvety skin. Here’s your step-by-step guide for how to use a beauty blender, plus how to clean it (and keep it from becoming an MUA’s nightmare). According to Patinkin, beauty sponges should generally be replaced every three months, but it ultimately depends on how often you wash them. If you’re diligent about cleaning your makeup tools, you should feasibly make it to the three-month mark. Just be sure to notice the tell-all signs when it’s time to toss it: “When you can no longer get the stains out or when they start to feel dry or get frayed, get yourself a replacement,” Patinkin says. Bonus points if you snag a recyclable sponge (like this antibacterial option). To extend the life of your beauty blender, try keeping two sponges at your disposal: one for liquids, one for powders. “Using the same for both wet and dry products will cause buildup, and you’ll lose that smooth, streak-free finish that a beauty blender is designed to deliver,” Frieri explains. You’ll still need to replace them both every few months, but you may get a little more use out of them, especially if you clean them both regularly.
