How often?
How often you clean your brushes depends on how often you use them and what type of product they are used for. For a powder brush used for bronzer, blush, and highlighter, the following guidelines may be helpful:
Weekly: For brushes used with powder products such as bronzer, blush, and highlighter, cleaning them once a week is sufficient.
Every other day: If you use your brush for cream products or liquid makeup such as foundation, you may want to consider cleaning it more often, perhaps every other day, as cream products tend to stick to the bristles more.
Regular cleaning helps keep your brushes fresh, reduces bacterial growth, and ensures even application of the products.
