2. Using dirty make-up brushes
It may feel like the last thing you have time for, but washing your make-up brushes, ideally once a week, ensures that you’re not applying dirt and bacteria to your skin with your make-up. First rinse off any residual make-up by holding the bristles under warm, running water, then cleanse with a gentle shampoo and warm water. Rinse again, then lay them flat on a towel to dry.
