We’ve already told you about Lancome’s revolutionary new mascara, the vibrating Oscellation. And while stars like Lindsay Lohan, Christina Ricci, Maggie Gyllenhaal and, of course, the brand’s own model Anne Hathaway have already lengthened their lashes with it, the rest of us have had to wait to try it out. Over 21,000 women have added their names to the wait list since we first reported on it — quite possibly an industry record — and your patience is finally being rewarded. The mascara launches today, and as one of the lucky few who have tried the stuff, we recommend that when you finally do get your hands on it, practice using slow, straight and steady strokes — no zig-zagging — to get the full, lash-lengthening effects. Click here to check out a video demo of the best techniques then — if you’re not one of the 21,000 who are already signed up — snag a tube for yourself.
