Sephora Collection Liquid Eyeliner is a great find for any beauty buff. It's on the low end of the price range of eyeliner you'll find on the shelves of a Sephora store. But does it perform? That all depends on what you're looking for in a liner.
Lately a bunch of brands have come out with new formulations and colors of liquid eyeliners. I'm not sure exactly how long Sephora's version has been around, but I don't think they're newbies. When I wear these I get lots of compliments on the colors.
