It's pretty much just a gimmick.





It has a little tinted shimmer/sparkle, doesn't actually do much though.








If you're looking for a good mascara... try CoverGirl Lashblast... it's amazing. Skip CoverGirl Volume Exact though, not so great.
More a gimmick than anything else. But there is a little bit of research in this. The metallics won't really help much but the colour tint suggested for your eye colour MAY help enhance your eye colour by providing a complementary colour as a backdrop against your irises.
