Most of the attendees at the Consumer Electronics Show, in January, were on the hunt for self-driving cars and improved smartphone cameras, but I arrived at the Las Vegas expo looking for high-tech innovations in beauty. I walked past the AI chemistry teachers and the robot puppy, and headed straight to the at-home lipstick maker and plaque-detecting toothbrush.

But new electric brushes are making this mundane experience more fun, more efficient, and more worthy of 120 seconds. This story originally appeared on Allure.
