Makeup brushes are the unsung heroes of any beauty routine—blending, buffing, and perfecting every look. As the ultimate workhorses of beauty tools, they also collect the most dirt and buildup. But let’s be honest—when was the last time you gave them a proper wash? If you can’t remember, it’s been too long.
By now, your brushes might be holding on to more than just leftover foundation. FYI, dirty brushes are a breeding ground for bacteria, oil buildup, and even breakouts. That’s why regular cleaning isn’t just a suggestion, it’s a must for healthy skin. The good news? Keeping them fresh is easier than you think—all it takes is the right technique. A small effort for a big payoff. Shall we?
Are dirty makeup brushes such a big deal?
Yes (side eye). It’s easy to keep dipping into your favorite bronzer or concealer without thinking about the buildup lingering on your brushes. But over time, that product accumulation mixes with oil, dead skin cells, and environmental debris. The result? A brush that’s less effective, rougher on the skin, and potentially teeming with bacteria.
Using dirty tools can clog pores, trigger breakouts, and cause irritation—or worse, infections. Those tiny red bumps on your face? They might not be from your skincare routine but from your neglected brushes.
Beyond the impact on your skin, dirty brushes simply don’t perform as well. A brush caked in old products won’t blend smoothly, leaving streaky or uneven makeup. Plus, the bristles wear down faster, becoming rougher and more prone to shedding. If you’re investing in quality brushes, regular cleaning is the key to keeping them soft, effective, and long-lasting.
The dirty truth: How often should you wash your makeup brushes?
How often you should clean your brushes depends on the type of product you use. If you’re working with liquid foundation, cream blush, or concealer, aim to wash those brushes at least once a week—wet formulas create a stickier breeding ground for bacteria. Powder brushes can go a little longer, around two weeks. But anything that touches your eyes (like eyeshadow or eyeliner brushes) should be cleaned weekly to prevent irritation or infections.
As for beauty sponges? They need a wash after every use. Since they absorb both product and moisture, they’re even more prone to bacteria buildup than brushes. If you’ve ever squeezed out a sponge and seen foundation oozing from the center, consider it a sign. You’re waiting way too long between cleans.
Check out how to clean your makeup brushes correctly…
Cleaning your brushes isn’t complicated, but technique matters. The goal is to remove buildup without damaging the bristles or weakening the glue that holds them together. While regular dish soap might seem like a quick fix, it can be too harsh. Instead, opt for a gentle shampoo, baby soap, or a dedicated brush cleanser. If your brushes have stubborn product buildup, pre-treat them with a small amount of olive or coconut oil to break down the residue before washing.
Next, pour a small amount of cleanser onto your palm or a textured brush cleaning mat, then swirl the bristles in circular motions. Keep massaging until the water runs clear, ensuring no residue is left behind. When rinsing, always hold the brush under running water with the bristles facing downward. This prevents water from seeping into the ferrule (the metal part that holds the bristles), which can loosen the glue and lead to shedding over time.
Once the soap and makeup are completely gone, give the brush a final rinse under clean water. Instead of twisting or pulling on the bristles, gently squeeze out excess water with a clean towel. To maintain their shape, never store damp brushes upright, as water can drip into the handle and weaken the adhesive. Instead, lay them flat on a towel with the bristles slightly hanging over the edge of a counter. Since brushes take about 8-12 hours to dry completely, washing them before bed ensures they’re fresh and ready for use by morning.
Extend the life of your makeup brushes with proper care
A high-quality brush set can last for years—if you treat it right. While regular cleaning is essential, proper storage is just as crucial. Instead of tossing brushes loosely into a makeup bag, where they can get crushed, pick up dirt, or have their bristles bent out of shape, store them in a brush holder or protective case to keep them in top condition.
If you’re searching for how to clean makeup brushes, chances are they’re already in good hands. That said, avoid relying too often on alcohol-based sprays as a quick fix. While they’re great for disinfecting, frequent use can dry out the bristles and shorten their lifespan.
Finally, know when to let go. If a brush starts shedding excessively, feels scratchy, or loses its shape despite careful washing, it’s time to replace it. At the end of the day, clean, top-condition brushes do more than just prevent breakouts—they enhance makeup application, making blending smoother and your overall routine more effortless. A little extra care goes a long way in keeping both your tools and your skin in top shape.
So if you’ve been putting off washing your brushes, take this as your sign to finally do it—your face will thank you.
