If my lashes look a little fuller and longer these days, it's thanks to the magic of Givenchy's Mister Lash Booster ($33, available exclusively at Sephora). Ingredients like extract of Artemia Salina and polymers help boost lash growth, prolong the growth cycle, and add curl and shine. The plastic bristle applicator and turn-click dispensing mechanism ensure the product can be applied precisely with minimal waste. Although Mister Lash Booster is suited for use as a lash serum at night and a pre-mascara primer during the day, I've been applying it before bed almost exclusively. Nevertheless, the results are (pardon the pun) eye-opening. It's not Latisse, but it's a pretty decent over-the-makeup-counter alternative.
