If we had to put it in a category, we’d file learning how to wash makeup brushes with meal prepping for the week and working through that pile of handwashing you’ve been ignoring in the corner of your wardrobe. It’s not fun, but you’ll feel suitably smug (and reap the benefits) when you do.
Before we dive head-first into the how, let’s recap why it’s so important to be regularly washing our best makeup brushes, from the best foundation brushes to the best eyeshadow ones. “Makeup brushes are notorious for harboring sebum, dirt, dust, product build-up and dead skin cells, all of which provide the ideal environment for bacteria to thrive,” says Benjamin Moffat, MD of brush cleaning brand ISOCLEAN. “This bacteria is then transferred to your face and has been shown to contribute to acne and other unwanted skin complaints.” So far, not so good.
