Mascara is one of the hardest products to review, because everyone's lashes are different and take to mascaras differently. I rarely review mascaras because I have a very sad story: I have typical Asian lashes - short, straight, almost non-existent. They're a little like Whoopi Goldberg's eyebrows.
I'm envious when I watch the non-Asian reviewers applying mascara and it boosting what's already there. For me, finding a mascara that produces a visible result is a huge accomplishment. The first mascara that accomplished this for me was Cover Girl Professional mascara. A few years back, I discovered the L'Oreal Voluminous line. There have been so many offspring of this original version that I can't keep it straight: Some have worked for me; some haven't. L'Oreal's Full Definition performed so well on me, I kept repurchasing it. Then, as it happens, it got discontinued.
I tried L'Oreal Superstar mascara on the hunch that a primer would help the helpless. To my amazement, the primer adds a level of volume and definition to the lashes. The mascara itself produces visible length and volume to my lashes. Here's the litmus test: If after I apply the mascara, my lashes touch my glasses, I know a measurable impact occurred. This happens every time I apply this mascara.
The brush is the standard L'Oreal Voluminous curved wand. The formula is thick but doesn't appear clumpy on the lashes. The mascara applies smoothly and leaves lashes evenly defined. After a day's wear, there is no flaking or smudging.
