By now, you’re probably using a homemade scrub for your body. But what about your…
Makeup brushes are some of the most valuable products in your makeup bag. Obviously, it’s important to have quality foundation, blush, and a nice eye shadow palette to highlight your peepers — but having dependable makeup brushes to apply those products is absolutely crucial. Makeup brushes are truly essential to any good beauty routine, and it can actually be quite fun to collect and maintain a solid group of these applicators.
However, when you use makeup brushes every day to apply your powder, blush, eyeshadow, bronzer, highlighter, or any other products you may use daily — the bristles on those brushes tend to become, well, dirty. And while you might not be able to see it with your naked eye, makeup brushes are usually much more filthy than you could ever imagine.
Just like your cell phone is crawling with ugly bacteria, your makeup brushes are full of stuff you definitely don’t want on your face. Even though they’re supposed help you look and feel your best, your makeup brushes can actually wreak absolute havoc on your skin. Here’s a look at the dirty truth about your makeup brushes.
Some makeup brushes get dirty enough to call for a daily wash
Makeup brushes may be more high maintenance than you probably realize.
If you are someone who wears makeup every day, it’s safe to say that makeup brushes are a necessity for you. And even if you only wear makeup a few times a week, your makeup brushes probably see quite a bit of action. Because of that — and because they can get really dirty — you makeup brushes should be washed regularly. In fact, Stowaway Cosmetics founder Julie Fredrickson told The Fashion Spot that she recommends people clean their makeup brushes after every single use, even if that means you have to wash them daily.
“Dab some on a cotton swab, twirl the brush and that is enough,” Fredrickson told the publication, explaining how to clean the brushes. She continued, saying, “Then, once a week, do a thorough cleaning with a cleanser that isn’t too harsh.” Added Fredrickson, “I personally use Dr. Bronner’s.”
Makeup brushes are loaded with fungi and other harmful bacteria
Obviously, your makeup brushes can get pretty dirty — especially if you’re a person who wears makeup every single day. But just how dirty do your brushes actually get?
Well, as it turns out, there’s a reason experts recommend regularly washing your makeup brushes — and it’s not just to remove old makeup products that are stuck on the bristles. According to the American Academy of Dermatology, makeup brushes that aren’t regularly cleaned can actually cause fungal infections, such E.coli — or even a life-threatening staph infection.
As reported by Insider, a study published in the Journal of Applied Microbiology looked at the presence of bacteria in makeup products and found that “70% to 90% of all of these products” contained fungus and bacteria, including E. coli — which can cause diarrhea, urinary tract infections, and respiratory illnesses (via CDC). Since you probably don’t want to just spread that all of that bacteria around your face, cleaning your makeup brushes is of utmost importance. No one wants E. coli on their cheekbones, no matter how much glow your favorite bronzer gives you.
Dirty makeup brushes can cause acne breakouts
Aside from makeup brushes just being plain dirty and gross, they can cause a lot of other issues for your skin, such as acne.
Even if you wash your face regularly — and even if you use clean makeup products that claim they don’t clog up your pores — your makeup brushes can still cause breakouts. Laramie, a professional makeup artist and the founder of Book Your Look, told Good Housekeeping that dirty makeup brushes are to blame for a lot of skin issues. “If you don’t wash your makeup brushes enough, you spread dirt and bacteria from your face, to your makeup, then back to your face,” they said. “If you’ve been breaking out and you’ve tried or ruled out everything else, your makeup brushes could be at fault.”
When you think about it, spreading dirt and even old makeup around on your skin really is cause for concern. And it’s safe to say that no one wants to revisit those old breakouts from their hormonal high school years – like, ever.
Makeup brushes can carry pink eye-causing bacteria
Makeup brushes are helpful when trying to make your eyes pop with the right eyeshadow combo. However, if you’re not careful, your makeup brushes could accentuate your eyes in a completely different way.
When you think of pinkeye, you probably picture red, watery eyes caused by a disease that really only affects schoolchildren. But as it turns out, your unwashed makeup brushes could potentially be carrying pinkeye bacteria, which means you could be just one smokey-eye look away from contracting the nasty disease — even though your school days are long behind you.
Now, while it’s unlikely that you’ll get pinkeye from just not washing your makeup brushes, your chance increases when you share makeup brushes with other people. The dirty truth about makeup brushes is that they can hold on to pinkeye bacteria and transmit it from one person to another. In fact, the Missouri Department of Health and Human Services even warns that sharing your dirty makeup tools with friends could result in a nasty case of pink eye. “Do not share eye makeup, face make-up, make-up brushes, contact lenses and containers, or eyeglasses,” the department’s website warns
Makeup brushes can even attract bugs
As if makeup brushes carrying around bacteria and fungus isn’t gross enough, we’re here to tell you that it gets even more disturbing.
As it turns out, your makeup brushes can also attract an entirely different kind of disgusting creatures: bugs. That’s right, the bristles that you use every day to apply your makeup can have tiny bugs hidden amongst them, and if that doesn’t freak you out, then keep reading — because, unfortunately, it gets worse.
Lynne Sanders, a cosmetic scientist and the founder of Cosmetics a La Carte, told Glamour that even though you can’t see them, there are probably bugs hiding out within the bristles of your makeup brushes. “Under the microscope, you may see the remains of mites on your brushes,” Sanders said. She continued, explaining, “Most of us have these tiny creatures, about a third of a millimeter long, residing at the base of our eyelashes and nose hairs, living off old skin cells and sebum.” Added Sanders, “They’re generally considered harmless, but they may be implicated in acne.” Harmless or not, we’d definitely rather avoid having bug remains spread all over our faces.
The dirtier the makeup brush, the less effective it is
Your makeup brush is supposed to provide full coverage; however, most people likely don’t know their makeup brushes are serving up a full face of germs.
Still, while most can agree that the germs, bacteria, fungi, and sometimes even bugs hiding out in your makeup brushes are disgusting, some folks might not think that it’s really necessary to wash their handy brushes every day. However, there’s another side effect of using dirty makeup brushes that just may make you want to invest in a good brush cleaner like, yesterday.
The dirtier your makeup bush is, the less effective it becomes. Not only are you spreading around germs on your face by using a makeup brush that hasn’t been properly cleaned in months, but you’re also not getting your money’s worth out of your go-to applicator. “A dirty brush doesn’t perform as well [when] distributing product,” Artis founder Matthew Waitesmith told The Fashion Spot, comparing the usefulness of a dirty brush to a clean one. Waitesmith continued, saying, “When a brush is dirty, many people try to push harder on the brush to get a result.”
Makeup brushes may irritate your skin if they aren’t cleaned regularly
Makeup brushes are meant to be a tool you can use in your quest to make your skin appear flawless. However, if you’re using a dirty makeup brush, you can expect to see blemishes and other skin spots appear due to irritation.
If you have sensitive skin, then you know how awful it can feel when something irritates your face. Unfortunately, that might become the new normal for you if you never wash your makeup brushes, as these applicators can seriously irritate your skin when they’re dirty.
Not only does not washing your makeup brushes cause them to become dirty, but it dries out your brush’s bristles, which can seriously hurt your skin the next time you go to powder your forehead (via Byrdie). Shawn Towne, global educator for jane iredale told New Beauty that a brush with dirty, dry bristles “also pushes the makeup into the skin, which can clog pores and irritate.” So, make sure you wash your makeup brushes regularly, especially if you have sensitive skin and want to avoid further irritation.
Makeup brushes aren’t meant to last forever
Makeup brushes may seem to be quite durable; however, even the highest quality brushes aren’t meant to last forever.
If you’re the type of person who stays on top of their makeup brushes’ cleansing routine, good for you! But, regularly cleaning your brushes doesn’t mean they’re going to last forever — nor should they. Sure, you might have spent a large amount of money on your beloved makeup brushes, but if you don’t replace them when needed, those expensive brushes aren’t doing you (or your skin) any good.
Expired makeup brushes make expired makeup that much worse
Makeup brushes aren’t the only items in your makeup bag that need to be thrown away and replaced from time to time.
Beauty and skincare products like foundation, eye shadow, mascara, eyeliner, and even sunscreen (just to name a few) all have expiration dates — and if you choose to apply expired makeup with old, dirty makeup brushes, you’ll only be worsening the negative effects old makeup can have on your skin.
