A tiny battery inside the wand powers the motion, which is meant to coat lashes more fully and in fewer strokes. Estée Lauder's TurboLash All Effects Motion Mascara ($30) is designed to separate lashes with its pulsating brush. Lancôme's Oscillation ($34) which comes out later this fall, aims to lengthen.

Holding a wand that shakes like a terrified Chihuahua and subtly hums like a phone on vibrate is strange enough. Maneuvering it gingerly from lash root to tip takes some practice. Do lashes look long and full after using them? Sure. More than they would had a battery not been involved? I'm not so sure. Still, something about the vibration makes the whole enterprise feel more thorough.

The Oscillation's official release isn't till November, but the company is offering a one-day preview sale at select Lancôme counters on July 31.
