8 Makeup Mistakes That Are Making Your Acne Worse

You most likely wash your shower towels at least once a week (if not, you certainly should!) so why should your makeup brushes be any different? They harbor tons of dirt, oil, grease, grime and all sorts of bacteria that you inevitably reapply on your skin with each use. According to Hadley King, MD, dermatologist at Skinney Med Spa and clinical instructor of dermatology at the Weill Medical College of Cornell University, this will increase your risk for more pimples and skin irritations. For this reason, she recommends washing your brushes at least once per week with warm water and a gentle cleanser or using the BeautyBlender Liquid Blendercleanser, $18, which easily does the cleansing for you.
