If we're honest, most of us are probably using brushes that choose us through circumstance, hand-me-downs, or freebies. But if you're looking to upgrade your application, you're going to need to invest in your tools. Think of it like painting a masterpiece, are you going to knock out your best work finger painting?
Before you run to the department store, it's important to note not all brushes are created equal, and because buying brushes indicates you're ready to make a certain degree of commitment to your makeup bag (read: investment). You want to do it right. Read on as we break down what each foundation brush type does (yes, terrifyingly there's more than one), and what's the best match for your foundation.
Also this isn't to say you have to play by the rules. As any pro knows, if what you're doing is working, stick to it. And if that means you're applying your foundation with a bronzer brush, or your fingers blend best, keep on doing you.
