I've been using Lancome mascara for years, Definicils being one of my very favorites. Tried Hypnose and was not so excited, but now I am thrilled with Grandiose. The brush is actually fun to use and makes it so easy to apply mascara and really lengthens my lashes because I can access every lash so easily. I just bought my second one. I haven't experienced any smudging at all and suggest it might be another factor causing this problem other than this mascara. Just sayin'
