When is the last time you cleaned your makeup brush? Cleaning makeup brushes should be a regular part of your beauty routine. However many of us forget this important step, so we clean them when they look visibly dirty. Brushes can harbor bacteria that may result in skin problems. It becomes counter-productive applying makeup because each time we do so with these brushes, we are introducing bacteria onto our skin, which results in breakouts, rashes and rough skin. Since the goal is beautiful healthy skin, using clean brushes is nearly as important as washing your face. Also, clean makeup brushes last longer and perform better. The frequency of cleaning depends on how often you use them. If you rarely use makeup, then you can get by with once or twice a month. If you use your makeup daily, wash them once or twice a week.
