Prescriptives has just introduced the first 24-Hour Longwear Mascara ($19.50). This ultra-comfortable, smudge resistant and waterproof mascara lifts, separates and defines lashes for up to 24 hours. An added bonus is that when it's worn over your favorite Prescriptives mascara, it becomes water-resistant. I really like the 360 degree plastic bristled comb, it reminds me of the one in the Cover Girl's Volume Exact Mascara. It lifts and combs each lash without clumping. Available in 2 colors: Black and Brown.
