Makeup brushes should be cleaned regularly to prevent bacteria build-up that can cause breakouts and other skin issues. The frequency of cleaning depends on the type of brush and how often it is used. Here are some general guidelines:
-
Brushes used with liquids or creams: These should be cleaned daily or at least once a week to prevent product and oil build-up, and a general clogging of the brush bristles.
-
Brushes used with powders: These can be cleaned less frequently, about once or twice a week.
-
Sponges: These should be washed after every use to prevent bacteria growth.
Its important to use a proper cleanser when cleaning makeup brushes. A gentle, slightly foaming cleanser is recommended to lather into the nooks and crannies of the porous brush bristles as you wash. There are also cleansers specifically made for cleaning makeup brushes that can be used.
In terms of replacing makeup brushes, its recommended to replace them every three to six months, depending on how often they are used and how well they are cared for.
