I have long lashes that curl naturaly with good volume, so it's perfect for me. Most mascara today have special volumizing, lenghtening or curling formulas there are almost no "ordinary" formulas. I also have very oily skin, even the waterproof formulas end up creating dark circle under my eyes after a few hours. But this mascara lasts all day, does not smudge even in extreme humid weather, I even slept with it on once and it looked as great in the morning as when I put it on the day before. It's extremely easy to remove if you use a lot of warm water. It does have a tendancy to clump my lashes together a bit.
