Can Dirty Makeup Brushes Cause Dermatitis?


Makeup brushes are an essential tool for achieving flawless beauty looks.

This accumulation of grime on makeup brushes not only affects their performance but also poses a potential risk to our skin health. In this article, we will explore the connection between dirty makeup brushes and dermatitis, a common skin condition. We will discuss the causes, symptoms, prevention, and treatment of dermatitis caused by unclean makeup brushes. So, if you want to maintain healthy and radiant skin, read on to find out more!

What is Dermatitis?

Dermatitis, also known as eczema, is a skin condition characterized by inflammation, redness, itching, and the formation of rashes or blisters. It can develop due to various causes, such as allergies, irritants, genetics, or even stress. When it comes to makeup brushes, certain factors can trigger dermatitis, making it essential to maintain clean brushes.

The Dangers of Dirty Makeup Brushes

When makeup brushes are not cleaned regularly, they accumulate oil, dead skin cells, makeup residue, and bacteria. These buildups create an ideal environment for the growth of harmful microbes, which can lead to skin infections and allergies. If you have sensitive skin, your risk for developing dermatitis from dirty makeup brushes increases significantly. The constant contact between dirty brushes and your skin can trigger an immune response, leading to inflammation and irritation.

Symptoms of Dermatitis Caused by Dirty Brushes

Dermatitis caused by dirty makeup brushes may manifest in several ways. Common symptoms include redness, itching, dryness, and a burning sensation on the affected area. In some cases, you may also notice small bumps, blisters, or swelling. These symptoms can appear immediately or after a few hours of using contaminated brushes. Additionally, dermatitis can spread if you continue using the same brushes without proper cleaning and maintenance.

Preventing Dermatitis: How to Keep Makeup Brushes Clean

Preventing dermatitis caused by dirty makeup brushes is relatively simple if you follow proper cleaning techniques. Here are some steps you can take to ensure your brushes remain clean and free from harmful bacteria:

1. Regular Cleaning: Make it a habit to clean your makeup brushes at least once a week. Use a gentle cleanser or a mild shampoo to remove all traces of makeup, oil, and dirt. Rinse thoroughly and let the brushes air-dry.

2. Disinfecting: To further eliminate bacteria, consider disinfecting your brushes by soaking them in a mixture of water and a small amount of vinegar or tea tree oil. This helps kill any remaining germs effectively.

3. Avoid Sharing: Sharing makeup brushes is a common practice, but it can increase the risk of spreading bacteria and infections. Make sure to use your own brushes and avoid borrowing or lending them.

4. Replace Regularly: Over time, makeup brushes wear out and the bristles may become less effective at distributing products evenly. As a general rule, replace your brushes every six to twelve months, or sooner if you notice signs of wear and tear.

Treating Dermatitis: How to Soothe Irritated Skin

If you suspect that your dirty makeup brushes have caused dermatitis, don't panic. There are several ways to alleviate the symptoms and promote healing:

1. Cleanse the Area: Gently wash the affected skin with a mild cleanser and lukewarm water. Pat dry with a clean towel.

2. Moisturize: Apply a fragrance-free, hypoallergenic moisturizer to the affected area to soothe dryness and minimize itching.

3. Topical Treatments: Over-the-counter creams containing hydrocortisone can help reduce inflammation and relieve itching. Be sure to follow the instructions carefully and consult a dermatologist if the symptoms persist.

4. Avoid Makeup: Give your skin a break from makeup until the dermatitis clears up. This will prevent further irritation and allow the skin to heal faster.


Dirty makeup brushes can indeed cause dermatitis, an uncomfortable and irritating skin condition. By regularly cleaning and maintaining your brushes, you can help prevent the accumulation of dirt and bacteria. Additionally, taking proper care of your skin and using hypoallergenic products can further minimize the risk of developing dermatitis. Remember, healthy and clean makeup brushes are essential not only for achieving flawless makeup looks but also for keeping your skin healthy and radiant. So, make it a priority to clean your makeup brushes regularly to say goodbye to dermatitis worries!
