This is the most dramatic mascara I've ever come across, which I consider a good thing. Not that you HAVE to make it dramatic, but it has that possibility. It makes my lashes quite long and thick and is very black, and you can keep layering it until it's almost ridiculous, but I don't find it to be too clumpy or spidery. I really do like this mascara a LOT. I'm one of those girls who doesn't think your eyelashes or hair can ever be big enough; when people say they want a natural mascara I'm like, Uh, WHY? Of course, you don't have to layer this on til it's almost like falsies, but my point is, you CAN! <3
I haven't had trouble with it flaking or smudging, but that's not a problem I typically have, either. Because it isn't waterproof, its one downfall is that it isn't the best at holding a curl, IMO. For that reason, I sometimes put a coat or two of L'oreal Voluminous Waterproof under it, let it dry, then use this.
