Honestly, it all boils down to the brush. All mascaras have almost the same formula. As a makeup artist for 10 years, I can atest to this. The masacra a brush is very flimsy because it's a "360" brush a.k.a. VERY flexible. The brush bristles are great at separating, but because it's so flimsy it's hard for the brush to grab on to the lashes.
