Since whipers of a revolutionary new mascara from Lancome started a few months ago, the beauty world’s been anxiously awaiting the launch of Oscellation, a vibrating mascara. So far only a few industry insiders and Lancome celebrity spokesmodels Anne Hathaway and Kate Winslet have been gifted with the top-secret stuff. And while most of the world will have to wait to test it out when it launches this fall, at a lunch yesterday with the mascara’s creator, Jean-Louis Gueret, Lancome revealed to PEOPLE that for one day only — today! — they’ll be releasing a limited supply for purchase before the official wide release in the fall. And we can tell you, it’s totally different from anything you’ve ever tried. The softly vibrating brush enables the formula to cloak your lashes, base to tips, in 360 degrees of the lush formula. Just push the button and slowly comb the humming brush in straight, smooth strokes through your lashes, building up with repeated sweeps. Click here now to join the ranks of the lucky few to try it out — today only.
