Here is what MAC's website says about this mascara:
Creamy formula builds glossy, natural-looking volume. Quickly coats lashes from root to tip. Keeps them light and flexible. The soft fibres of the football-shaped brush deliver maximum payoff. No smudging.
So, I really want to like this mascara. So much so that I keep using it over and over (probably used it for a good week a half after taking pics and writing most of this review, hoping I was wrong), but really it's a no go.
I like the brush of this mascara quite a bit. It easily grabs lashes for application, I don't have to push the mascara on to my lashes nor did I have issues with clumping. Really, it gives good volume that is natural looking, adds a bit of length and I love the look. Right after application.
About the 10-12 hour mark, things just seem to go down-hill fast. I develop flakes and smudges, which you can't see in the pic above because the mess is actually down on my cheekbone and then below. Strange. I also lose volume and length. It just looks... blah. Like I slept in my makeup, but I haven't been to bed yet.
So, I like this mascara for short time periods. More than that and I'd search for a different mascara to wear.
