SANITATION IS ALWAYS KEY
After you've cleaned your makeup brushes with your favorite brush cleaner or soap, it's also important to sanitize them as well. In addition to your makeup bag, brush holder, vanity area and any surface you may use during makeup application with 70% alcohol.
Disinfecting with 70% versus 91% or higher has more germ killing power compared to something more concentrated. Plus anything higher evaporates too quickly to be effective.
Here's How:
Pour a small amount of the rubbing alcohol into a glass bowl and quickly dip the brush several times.
Squeeze, blot and gently wipe dry with a clean paper towel.
Dry your brushes upside down to prevent the brush hairs from falling out. Because laying them flat can cause the glue holding the brush hairs inside the ferrule can become loose.
