How Often to Clean Your Makeup Brushes: The Basics

Makeup brushes are tools that hold onto product residue, bacteria, and dead skin cells with every use. Understanding how often to clean them is important for maintaining healthy skin and extending the life of your brushes. The general recommendation from makeup artists and dermatologists is to wash brushes used on the face at least once per week. Brushes used around the eye area should be cleaned even more frequently—ideally two to three times per week—since the eye area is more sensitive and prone to infections like conjunctivitis.

However, the actual cleaning frequency depends on several factors. If you have acne-prone, oily, or sensitive skin, you may want to wash your brushes more than once weekly. People with these skin types are more susceptible to bacterial buildup that accumulates on brushes. Similarly, if you use cream or liquid products rather than powders, your brushes will hold onto product longer and may need more frequent washing. Environmental factors matter too—if you live in a humid climate or exercise regularly, sweat and moisture on your skin can promote bacterial growth on brushes more quickly.

The type of brush also influences cleaning frequency. Foundation brushes, which come into contact with larger surface areas of your face and pick up more bacteria, benefit from weekly or twice-weekly cleaning. Powder brushes can sometimes go longer between washes since powder products are less likely to harbor bacteria than liquid formulas. Eyeshadow brushes, which touch the delicate eye area, should be cleaned at least twice weekly. Concealer brushes that target blemishes or problem areas should be washed frequently to avoid spreading bacteria.

• Face foundation brushes: clean weekly
• Eyeshadow and eyeliner brushes: clean 2-3 times per week
• Powder brushes: clean weekly to bi-weekly
• Concealer brushes for blemishes: clean 2-3 times weekly
• Lip brushes: clean after every use or several times per week

Practical Takeaway: Start with a baseline schedule of washing face brushes weekly and eye brushes twice weekly. Adjust based on your skin type and the products you use. If you notice breakouts or irritation appearing in places where you use brushes, increase your cleaning frequency.

What Happens When You Don't Clean Your Brushes Regularly

Neglecting to clean makeup brushes creates an environment where bacteria thrive. Brushes that go unwashed accumulate layers of old makeup, oils from your skin, sweat, and environmental debris. A study published in the American Journal of Infection Control examined makeup brushes and found that they can harbor significant levels of bacteria, including Staphylococcus aureus and other pathogens. These bacteria multiply rapidly in the warm, moist environment created by leftover product and natural skin oils on brush bristles.

When dirty brushes contact your skin repeatedly, they transfer bacteria directly onto your face. This can lead to acne breakouts, even in people who don't typically have acne-prone skin. The bacteria can also cause folliculitis, an infection of the hair follicles that appears as small red bumps, or more serious conditions like staph infections. People with compromised immune systems, existing skin conditions, or those prone to infections face higher risks from unwashed brushes. Additionally, if you share brushes with others without cleaning them first, you risk transmitting skin infections between people.

Beyond skin health concerns, unwashed brushes deteriorate faster. Dried product buildup in the bristles causes them to become stiff and clumpy, making application uneven. The bristles can separate or break off more easily when caked with product. Over time, the bristle structure weakens, and the brush loses its ability to pick up and distribute product smoothly. Brushes that cost $15 to $50 or more can be ruined prematurely by skipping regular cleaning, making cleaning an economical practice as well as a health one.

Visible signs that your brushes need immediate cleaning include discoloration in the bristles, a noticeably stiff texture, visible product crusting at the base of the bristles, or an unpleasant odor. If you notice any of these signs, wash your brushes right away rather than waiting for your scheduled cleaning day.

Practical Takeaway: Regular brush cleaning prevents skin infections, breakouts, and premature brush deterioration. Even if your schedule is busy, dedicating 15-20 minutes weekly to brush cleaning is an investment in both your skin health and your makeup tools.

The Right Way to Clean Your Makeup Brushes

Cleaning makeup brushes effectively requires using the right cleanser and technique. While some people use regular shampoo, a dedicated brush cleanser or gentle soap works better. Many professional makeup artists recommend using a solid brush cleaner—a small circular disc with grooves that you wet and rub your brush bristles against. Popular solid cleansers include the Beautyblender Solid or Cinema Secrets Professional Brush Cleaner. These products are specifically formulated to break down makeup product while being gentle enough not to damage delicate bristles. If you don't have a brush cleaner, baby shampoo or a gentle clarifying shampoo works reasonably well for occasional cleaning.

For a basic cleaning method, wet your brush with lukewarm water and apply cleanser directly to the bristles. Using a circular motion in the palm of your hand, gently work the cleanser through the bristles. The goal is to work the cleanser in from the tip toward the base without being too aggressive. Pay special attention to the base of the bristles where product buildup occurs most heavily. Rinse thoroughly under running water until the water runs clear and no soap residue remains. Repeat if needed for brushes with heavy product buildup. After rinsing, gently squeeze out excess water without wringing or twisting the bristles.

The solid cleaner disc method is slightly different. Wet the disc and your brush, then rub the bristles against the grooved surface using a circular motion. This works well because the grooved texture helps lift product from between the bristles. The disc method is efficient for cleaning multiple brushes in succession. Some people prefer to use both methods together—using the disc first to remove heavy product, then finishing with a gentle soap wash for a thorough clean.

After cleaning, proper drying is essential. Lay brushes flat on a clean towel or on a brush drying rack, with bristles hanging slightly over the edge if possible. Never stand brushes upright in a cup while wet, as water running down to the ferrule (the metal part holding bristles) can damage the glue holding bristles together and cause them to shed. Allow brushes to air dry completely before using them again, which typically takes 4-8 hours depending on humidity. Some people prefer to clean brushes before bed so they dry overnight.

• Use lukewarm water, not hot
• Use a brush-specific cleanser or gentle soap
• Work cleanser in with a gentle circular motion
• Rinse completely until water runs clear
• Squeeze gently to remove water—don't wring
• Lay flat to dry, not standing upright
• Allow 4-8 hours for complete drying

Practical Takeaway: Invest in one solid brush cleaner disc (usually $8-15), which lasts months and makes weekly cleaning quick and effective. Dedicate 15-20 minutes once or twice weekly to wash and lay out brushes to dry overnight or during the day.

Cleaning Schedules for Different Brush Types

Different brushes serve different purposes and come into contact with different areas of your face, which means they require different cleaning schedules. Foundation and powder brushes apply base makeup to large areas of your face and pick up significant amounts of bacteria and skin oils. These should be cleaned weekly at minimum. If you use a foundation brush daily and have acne-prone skin, washing twice weekly is reasonable. Stippling or buffing brushes used for foundation can be washed weekly but may benefit from twice-weekly cleaning if you notice breakouts.
