4.25 How to Washing Makeup BrushesNo matter how busy your schedule or minimalist your makeup routine, the one step you should never skip is cleaning your makeup brushes. Brushes provide a great area for bacteria to grow, as they accumulate dirt and dust. This, in turn, can lead to infections, acne, and other skin problems.

If you want an efficient routine, these step-by-step instructions will teach you how to clean makeup brushes in less than five minutes:

1. Turn on your faucet and let the water run until it is warm. Meanwhile, set aside all your dirty brushes, get a cleansing agent (a mild shampoo, liquid hand soap, or brush cleanser), and lay out a clean towel or paper towel on your counter.

2. For face brushes (e.g., large powder brushes, buffing brushes, bronzer brushes, blush brushes, and foundation brushes), wet the hairs of the brush with warm water. Apply the cleansing agent, making sure to use your fingers to press the product through the hairs of the brush. Add a little water while you work, so that the product foams, and be sure to keep the hairs of the brush pointing down.

3. Rinse and repeat the process of wetting the hairs of the brush and applying product until the water runs clear.

4. After the brushes are properly cleaned, pat them down on the towel and let them lie on their side. It is important to not place the brush upright to dry, as residual water can run down the handle and loosen the glue that is holding the brush and the handle together.

5. For eye brushes (e.g., a flat eyeliner brush, eye shadow brush, or smudge brush), repeat steps two to four but make sure to use less product and rinse the brush under the water for 20 seconds longer, as residual chemicals in eye brushes can irritate your eye.

6. For cleaning a lash and brow groomer brush, which has a comb on one side and a brush on the other, use a paper towel with water and a drop of cleansing product to wipe out the comb side of the brush. Then repeat steps two to four for the brush side.

Now that you know how to clean makeup brushes, it’s crucial to know the recommended frequency. While dermatologists recommend that you clean your brush at least monthly, most advise cleaning them on a weekly basis. How often do you clean your makeup brushes?
