Can Makeup Brushes Cause Acne? Yes—Here’s Why and How to Stop It

Short Answer: Yes, Dirty Makeup Brushes Can Cause Acne.

 

If you’ve been wondering why your skin keeps breaking out—even when you’re using great skincare and quality makeup—the answer might be hiding in your brush holder.

 

At Ana Kay Beauty Academy, we teach all our students this fundamental truth: clean tools = clean skin. Dirty brushes are breeding grounds for acne-causing bacteria, clogged pores, and unwanted irritation.

Here’s Why Makeup Brushes Cause Acne

 

1. They Trap Oil, Dirt & Dead Skin

 

Each time you use your brush, it picks up:

    •    Sebum (oil from your skin)

    •    Dead skin cells

    •    Old makeup

    •    Environmental pollutants

 

If left unwashed, brushes accumulate this gunk—and reapply it every time you use them.

2. They Harbor Bacteria

 

Unwashed brushes create the perfect warm, damp environment for bacteria like Propionibacterium acnes to thrive.

This bacteria can spread across your face, causing:

    •    Whiteheads

    •    Blackheads

    •    Inflamed pimples

    •    Irritated skin

 

And if you’re sharing brushes or using them on clients? You’re also spreading bacteria from person to person.

3. They Disrupt Your Skincare Routine

 

You can invest in the best serums, cleansers, or facials—but if you’re applying makeup with contaminated tools, you’re reintroducing debris that counteracts all that skincare effort.

How to Stop Breakouts from Makeup Brushes

 

1. Wash Brushes Regularly

    •    Foundation/concealer brushes: Clean every 1–2 uses

    •    Powder/bronzer brushes: Weekly

    •    Eyeshadow brushes: Every 3–4 days

 

Use a gentle cleanser or baby shampoo, rinse with warm water, and let them air dry flat.

 

2. Avoid These Mistakes:

    •    Don’t soak brushes upright. This can rot the glue.

    •    Never use dirty brushes on clean skin. It undoes your whole skincare routine.

    •    Don’t store wet brushes in closed bags. This traps moisture and grows mold.
