HOW OFTEN should you clean makeup brushes?
For concealer and foundation brushes, at least once a week to prevent a build-up of product. And because these brushes are used on your face, the cleaner, the better. Brushes that are used around the eyes should be cleaned at least twice a month, while all others can be washed once a month.
How do you do it?
The best and most thorough method for cleaning your makeup brushes requires only water and either a gentle soap or brush cleanser. Wet the bristles with lukewarm water, place a drop of soap or cleanser into the palm of your hand, and gently massage the tips of the bristles in your palm. Rinse the bristles, squeeze out the excess moisture with a clean towel, reshape the brush head, and let the brush dry with its bristles hanging off the edge of a counter.
How do you know when a brush is just kaput?
When the bristles start to fray, shed, or lose their shape. If your brushes become too pinched or squashed, then they simply will not be up to the job.
