The Bobbi Brown Intensifying Long-Wear Mascara produces really natural looking lashes and is a mascara that cant really be built up to look more intense. The small brush is great as you can get really close to the lash line. The formula is fantastic - lasts all day with no smudging or flaking but easily removed with warm water on a cotton pad.
I've just started using this inside my top lid, as invisible eyeliner. It gives drama and emphasis to my eyes, without looking too harsh. My colour is Black Smoke, and I run it backwards and forwards, right next to lashes. Lasts all day, even with watery eyes.
