We all know it, but we’re often too lazy to do it on a regular basis. We use our makeup brushes daily, and it comes into direct contact with our skin. While it picks up our makeup, it’ll pick up bacteria and our dead skin cells too. Imagine using that to brush against our face every day, it’ll definitely irritate our skin and cause acne to appear. Make it a habit to wash your brushes fortnightly, or at least when your brushes are no longer soft and there is visible residue on them.
