I definitely don’t wash mine enough. I probably do them once a month but I would like to purchase a good cleaner and do them more often to help with bacteria etc

I dont really have a set time or routine.
I tend to wash them when I feel that they need it and when I have time.
I do however have several brushes so I easily sideline ones that need a clean until im ready to have a brush cleaning morning,.

I try to at least once a month. I find if I wait too long in between my skin makes it very clear that the brushes aren’t in the beat condition
