We're teaming with Sephora to celebrate the Best of Sephora. Sephora's clients have voted and now we reveal the results of what they thought were the best products. Each day represents a different best of category from concealer to shampoo, eye treatment to tools. Congratulations to all of the brands!

Today's winners are all eyeliners, and the one that came out on top is Sephora's own Slim Pencil for Eyes. Other top picks are Urban Decay 24/7 Glide-On Eye Pencil in Zero, Smashbox Cream Eye Liner in Caviar, Stila Smudge Pots in Black, and Make Up For Ever Aqua Eyes in Mat Black 0L.

To enter today's giveaway, leave a comment in the comments section below by 5 p.m. PDT / 8 p.m. EDT Monday, September 10, and we'll announce the winner tomorrow. Please, only ONE comment per person; duplicate comments will be discarded, so commenting more than once won't up your chances of winning.
