I had been using MAC Fluidline for over a decade now. I love the pigmentation, its staying power, the fact that I don't look like a raccoon later in the day... However, as I grow into my almost-30s, I've noticed that my trusty Blacktrack was starting to look a little *harsh. Thank goodness for Lowlights! It's everything I love about Blacktrack, but subtler and more mature. LOVE! New staple in my makeup bag :)
