Why Cleaning Makeup Brushes Matters
Dirty makeup brushes accumulate a lot of bacteria, dirt, oils, and even dead skin cells. This worsens over long periods, leading to the use of unwashed brushes to result in the following setbacks:
- Triggering acne
- Skin irritation
- Uneven makeup application
- The shortened lifespan of your brushes
Journal of Applied Microbiology published a fascinating study claiming more than 90% of tested makeup brushes contained harmful bacteria after just one month without cleaning, primarily due to neglect. Regular washing reduces this risk dramatically.

Let brush heads rest on a countertop and dry face down for optimal bristle airflow.
