Summary: I loved the DiorShow mascara as I have fine, non-existent lashes that came to life with one coat, but I should warn that after a few hours there is a little flaking that can occur with their formulation. The challenger, Lancome's Hypnose, is a decent mascara but I didn't see the same volume as with DiorShow and found the formulation weighed down my lashes. Though my lashes appeared full, they looked quite a bit shorter which was an issue for me as I love getting the look of thick, long lashes with the use of only one mascara (as oppose to layering volumizing and lengthening mascaras as some pros reccomend).
