Don't clean your makeup brushes regularly? You might wanna start being a bit more routine about it.

Why? The side effects can be more dramatic than a smoky eye! Brace yourselves gals -- it turns out your favorite go-to beauty solution could actually be your skin's worst enemy. OMG!

A recent survey of women just released by Anisa International found 39% of women who use makeup brushes don't clean them even once a month. Even worse, 22% admitted never cleaning them at all.

So why are women avoiding the makeup brush cleanse? Check out the statistical reasons:

• 22% of women say they take too long to clean or dry
• One in five (21%) weren't even aware they needed to clean their makeup brushes
• 17% say they don't know how to clean them properly -- ask Millennials and that number jumps up all the way up to 31%

"Today's consumers are spending a significant amount on cosmetic brushes in order to achieve desired makeup looks, but they're not protecting their investment or their skin by properly caring for these tools," said Telwar-Kaicker.

"This survey indicates that there's a need for beauty brands to educate consumers about the importance of cleaning, the proper techniques and the revolutionary new products available that minimize the amount of time it takes."
