What's Really Living in Your Makeup Brushes? Why Experts Say Cleaning Them Matters

Beauty experts say, "Dirty makeup brushes are one of the most overlooked causes of breakouts and skin irritation." And if you haven’t washed yours in a while, you’re probably way overdue.

They pick up more than makeup
Every time a brush touches your skin, it picks up more than just product. Natural oils, sweat, dead skin cells,s and leftover makeup get trapped in between the bristles. 

Let that build up for weeks, ks and you've pretty much created a mini petri dish. A damp bathroom environment plus bacteria and fungi equals everything they need to thrive.

It's not just hygiene,” a makeup artist said. That’s what you’re putting on your skin every single day.”

Can dirty makeup brushes hurt your skin?
Using an unwashed brush won’t send most people to the doctor. But it can also lead to clogged pores, acne, redness and irritation. If you have sensitive skin, the response is usually faster.

Eye brushes deserve special care. The skin around your eyes is delicate, and bacteria there can lead to itching, redness, ness or even minor infections if hygiene is not maintained.

How often should you clean those?
The rule depends on the use you will make of the brush.

- Foundation and concealer brushes: Wash at least weekly. Liquids trap more bacteria, and they touch a large area of skin.
- Powder brushes: Usually once a week or every two weeks is enough. 
- Beauty sponges: Rinse after each use, and give a deep clean weekly. They soak up more product and moisture.

Wash with a mild soap or gentle cleanser, rinse well, and lay flat to air dry. The glue can be loosened by wet bristles when dried upright and ruin the shape.

A few simple habits can go a long way
You don’t need a 10-step routine to keep your brushes clean.

1. No sharing of brushes. What works for your friend’s skin may not work on yours.
2. Keep them dry. Store them in a clean container, not loosely in a drawer. When you can, keep them out of steamy bathrooms.
3. Replace as necessary. If the bristles are falling out, bent, or feel rough, it’s time for a new one.
4. Check expiry dates. Old makeup breaks down and contributes to the gunk on your tools.

And clean brushes mean the product applies better. You’ll use less makeup, get smoother coverage,ge and give your skin a better chance to stay clear.

So, clean your brushes before you do your next glam look. You’ll thank your skin.
