This is the spiel from the Covergirl website:
"Get 4x brighter eyes* with Exact Eyelights Mascara! Light-reflecting metallics and a hint of tint bring out your blues, browns, hazels and greens, while our patented no-clump brush helps define lashes.
* vs. bare lashes "
Hmm... I should have known better but Rihanna looked so pretty in the promo picture and I was just really intrigued by the concept of a mascara providing 'brighter eyes' on the basis of your eye colour so I gave it a try.
Firstly here's the brush. It's nothing special. I was really underwhelmed when I took it out but I've been proven wrong before by brushes that look normal but work wonders on the lashes.
Apparently there's some light reflecting glitter or something in the mascara that results in this eye brightening effect. I'll let you judge for yourself below:
I can't deny the fact that the mascara seems to give pretty good length and it didn't clump. I didn't like the fact that it just makes your lashes stick straight out without providing a natural curl. In terms of eye brightening though, I'm seeing no effect. My friend pointed out to me that because the flash in the picture where I'm wearing the mascara was a bit brighter, I actually do look like I have brighter eyes but I swear the effect is from the lighting and not the product! That's the reason why I consider it to be a beauty fail. Don't sell me something on the basis of an effect that your product doesn't provide! The only reviews supporting an eye brightening effect seem to be on the Covergirl website which seems a bit biased to me but anyway, that's my rant for the day.
