Essentially a miniature dishwasher for your brushes, BrushPearl Cosmetic Brush Cleaner and Cleanser, $99, is the first product of its kind. Utilizing ultrasonic technology, the tiny machine sends -- wait for it -- sound waves through the water and the brand's signature cleanser, essentially vibrating and shaking leftover makeup from your brushes. The machine may cost a pretty penny, but can you really put a price tag on the peace of mind you get from squeaky-clean brushes?
