Perhaps you've heard the buzz. Maybelline is joining the vibrating mascara craze with the release of its newest mascara, called Pulse Perfection ($15). The latest addition, the first of its kind in the drugstore variety, won't be available until July. However, Maybelline's offering up a chance for you to preview the battery-powered mascara for today only. Just follow this link to be one of the first people to give the Maybelline Pulse Perfection a spin; and be sure to look for my review on the new product tomorrow.
