My eyelashes tend to massacre any mascara. I usually get smudges wearing mascara hence I always skipped using mascara. However, I decided to give this a go since I heard rave reviews about it. Now, I can second the good reviews. I love how natural and defined my lashes looked after an application. If I want to make my eyes look more dramatic, I just applied more layers. The formula is on the dryer side (not sure whether this is just mine or the original texture) but that doesn't bother me. I think that's why it didn't smudge on my lids too. So far, I love this mascara and recommend this to those who sweat a lot or live in humid areas.
