Shocking Truth: Your Makeup Brushes Are Full of Bacteria—Here’s Why You Need to Clean Them NOW!

Makeup brushes are essential tools for a flawless look, but they can also become breeding grounds for bacteria and other harmful microorganisms if not cleaned regularly. Many people neglect cleaning their brushes, but experts recommend washing them at least once a week to avoid skin irritations, acne, and more serious issues like eye infections.

Here’s everything you need to know about how to clean makeup brushes properly, along with expert insights and time-saving tips to make the process efficient.

Why You Should Clean Your Makeup Brushes Regularly

Dirty makeup brushes can quickly accumulate sebum, dust, dead skin cells, and product buildup. As Dr. Anne Chapas, a dermatologist, explains, “Makeup brushes accumulate sebum, pollution, dust, bacteria, dead skin cells, and product buildup,” all of which can cause clogged pores, acne, and even E. coli infections. Brushes used around the eyes or for liquid makeup should be cleaned after every use to prevent the growth of germs, which thrive in moist environments.

A study by Spectrum Collections found that makeup brushes, no matter where they’re stored—on a vanity, in a makeup bag, or in a drawer—harbor bacteria levels equal to or higher than those on a toilet seat. Researchers swabbed both clean and dirty brushes after two weeks of use. Cosmetic scientist Carly Musleh explained that dirty brushes can transfer bacteria, dead skin cells, and oils to the face, potentially causing acne or more serious skin issues like Staph infections. The study also revealed that while 40% of customers clean their brushes biweekly, 20% only wash them once every one to three months, highlighting the need for regular cleaning to prevent bacterial buildup.

What You Need to Clean Makeup Brushes

1. Soap and Water: Any mild soap can work for cleaning, but antibacterial soap is particularly effective for synthetic brushes as it helps remove stubborn buildup. If you’re using brushes with natural hair, opt for a gentle, unscented soap to preserve the integrity of the bristles.
2. Brush Cleaner: For brushes used around the eyes or with liquid makeup, a daily brush cleaner can make cleaning faster and more efficient, especially for sensitive skin.
3. Warm Water: Avoid hot water, as it can damage the bristles and loosen the glue that holds them together. Lukewarm water is the sweet spot to ensure a deep clean without any harm.
4. Brush-Washing Mat: While you can use your hand, a brush-washing mat with grooves helps get into every bristle for a more thorough clean. This accessory makes the process quicker and ensures you’re not missing any product buildup.
5. Drying Rack: After washing, always dry your brushes lying flat or with the bristles pointing downwards to prevent water from seeping into the ferrule (the metal part of the brush), which could cause the brush to fall apart.

How to Clean Your Brushes Step by Step

1. Wet the Bristles: Begin by gently wetting the bristles with lukewarm water. Hold the brush so that water flows downward, keeping it away from the ferrule. This prevents water from damaging the glue that holds the brush hairs in place.
2. Apply Soap: Squeeze a small amount of your chosen soap or shampoo into your palm or onto the brush-washing mat. Gently swirl the brush in the soap for about 15 seconds to dislodge any buildup of makeup, dirt, or oil.
3. Rinse Thoroughly: Rinse the brush under lukewarm water until the water runs clear, ensuring that all soap and debris are gone. Be careful not to let water seep into the ferrule, as this can loosen the bristles or cause shedding.
4. Dry the Brush: Gently squeeze out excess water from the bristles, using a towel if necessary. Lay the brush flat to air-dry on a clean surface, or use a drying rack to keep it upright, bristles facing down.

Expert Tips for Maintaining Your Brushes

1. Frequency: Makeup artist Mario Dedivanovic advises, “For eye brushes and brushes used with liquid makeup, it’s important to clean them after every use. These brushes come into contact with moisture, which can harbor bacteria.”
2. Be Gentle with Natural Bristles: Brushes with natural hair are more delicate, so use a mild soap and consider conditioning them to keep the bristles soft and intact. Dedivanovic suggests, “You should definitely be more careful washing natural brushes. A little conditioner after washing helps soften and detangle the natural hairs.”
3. Avoid Hot Water: Charlotte Tilbury, a renowned makeup artist, cautions, “Avoid using hot water to clean your brushes, as it can damage the bristles and the ferrule.”
4. Store Brushes Properly: Once your brushes are completely dry, store them in a clean, dry place, separate from your makeup. Dr. Chapas recommends storing brushes in a dry makeup bag or on a clean drying rack to avoid cross-contamination.

Studies Supporting the Importance of Brush Cleaning

Several studies have highlighted the risks associated with dirty makeup tools. A 2018 study published in the Journal of Cosmetic Dermatology found that dirty makeup brushes could lead to bacterial growth on the skin, exacerbating conditions like acne and dermatitis. In a similar study conducted by the American Academy of Dermatology, researchers concluded that unclean brushes can cause outbreaks of Staphylococcus aureus, leading to skin infections and other health issues.

Conclusion
