Using clean makeup brushes is essential for maintaining clear and healthy skin. Here's why dirty makeup brushes can have a negative impact on your skin:
Over time, makeup brushes accumulate bacteria, grime, oils, and dead skin cells. When these substances build up on the filaments, they can be transferred back onto the skin.
If you have exposed wounds or acne-prone skin, using these brushes on your face can increase your risk of infection.
Dirty brushes may contain remnants of previous makeup products, which can contaminate new products. This can affect the color payoff and texture of your makeup.
