This weekend, I tried Benefit's Roller Lash Mascara and LOVED it.
The brush: pink, plastic with the little short 'spikes', and curved. Gives really great control - I could get right against the lid and in the outer corner. Also, an advantage of the curved brush is that you can really push the lashes up and out. This helps to open up your eyes and make 'em pop.
The formula: smooth, wet, but dries fast. Easy to spread equally on the lashes and also layers really well. One downside: a little tough to add more layers on once it has dried. Some mascaras are more malleable than others later in the day - this one dries right up so you can't be lazy and add more if you're going out at night (my style). This one is also long-lasting - doesn't flake or smudge throughout the day...yes! In the fist pic above, the eye on the left is wearing mascara and the right is not. Also, all the pics in the post have NO liner, and NO shadow - JUST mascara.
