Make-up brushes collect natural oils from your skin and some residue of make-up products like foundation and compact. The oily surface then attracts a lot of dust. Moreover, the foundation bits begin to rot on the brush fibres. Now, you wouldn’t want to expose your skin to a grimy make-up brush. You do not need to wash the brush after every use. But, once a month (based on how frequently you use the brush) is highly recommended.
