Volumizing mascaras are hit or miss for me. I wouldn't say I have thick lashes, but volumizing mascaras tend to make my lashes clump up, even with the most practiced application. I end up having to comb some of the mascara out with a lash comb. This is one of those mascaras.
I think it's a great product from a great brand, but this one didn't work for me. I need something that separates lashes more than this one. For reference, my favorite mascara is smashbox superfan. To date, I haven't found a mascara that separates my clumpy lashes any better than this one. I also have in my collection benefit's "They're Real" in brown, and a handful of others not worth mentioning that don't make the cut for me .
I recommend this benefit product for those who really want to add some volume and chunkiness to their lashes. It's probably not a great choice if you have lashes prone to clumping like mine.
