What type of brush cleaner you should use depends on how many brushes you have in your collection and your personal makeup habits. From DIY options to instant brush cleaners to deep-cleaning shampoos and fancy tools, there are a ton of makeup brush cleansers on the market.
If you have an effective makeup brush cleaner, you'll be less likely to put off the task. Having a good cleansing method takes a lot of the stress and guesswork out of the situation. The American Academy of Dermatology recommends a full cleaning of your makeup brushes every seven to 10 days in order to wash away any harmful bacteria and buildup that could irritate your skin.
But please, don't take that as your signal.
