Pour the brush cleanser into an appropriate case for the brush to soak.
Leave the brush in the cleanser for a few minutes and then softly agitate in a circular motion.
Rinse thoroughly with tepid running water.
Lightly dry with tissue and lay the brush down to maintain its original shape for complete drying.
A makeup brush should be cleansed at least once a week as it can cause skin problems if it is not cleaned enough due to dust or sebum in the brush when makeup is applied.
