It is essential to keep makeup brushes clean to maintain good hygiene and ensure the longevity of your brushes. The frequency with which you should clean or change your makeup brushes can depend on several factors, including how often you use them, the types of products you use, and your skin type. Madina Nabunya, a make-up artist gives some general guidelines:

1. Foundation brushes and sponges: If you use foundation brushes or sponges daily, it’s a good idea to clean them at least once a week. If you have acne-prone or sensitive skin, you may want to clean them more frequently.
2. Eye makeup brushes: Brushes used for eye makeup, such as eyeshadow and eyeliner brushes, should be cleaned regularly, ideally once a week if you use them frequently. Cleaning these brushes prevents the buildup of bacteria and ensures the colors applied remain true.
3. Blush and powder brushes: Brushes used for powder-based products like blush, bronzer, and setting powder can be cleaned less frequently, perhaps every two weeks or once a month, depending on use.
4. Lip brushes: If you use a lip brush, it’s best to clean it after each use to prevent color contamination.
5. Natural vs synthetic brushes: Natural hair brushes tend to hold onto product more, so they may need more frequent cleaning than synthetic brushes.
6. Disposable brushes or applicators: If you use disposable applicators, like those that come with some eyeshadow palettes or lipsticks, you should use them only once and then dispose of them.
7. Spot cleaning: In addition to regular deep cleaning, you can use a brush cleaner or alcohol-based spray to spot clean brushes in between uses. This is particularly useful for eyeshadow brushes when you want to switch between colors.

When to replace

Brushes should be replaced when they start shedding bristles, lose their shape, or no longer perform as effectively. High-quality brushes can last for several years with proper care.

To clean your brushes, you can use a gentle brush cleaner or a mixture of mild soap and lukewarm water. Be sure to rinse thoroughly and reshape the bristles before allowing them to air dry. Avoid soaking the brushes in water for extended periods, as this can damage the bristles or the adhesive that holds them together.

Remember that keeping your makeup brushes clean is essential not only for the health of your skin but also for achieving the best makeup application results.
