Thanks to our very generous friends at Sephora, we're giving away a different product every day throughout the month of June. Congratulations to TammyFir, who won yesterday's giveaway for Dior Diorshow Black Out Mascara.

This week, we're featuring products exclusively available at Sephora, such as Kinerase Ultimate Day Moisturizer ($125). This brilliant potion smooths dry skin, reduces blotchiness, improves tone and minimizes wrinkles because of its high levels of Kinetin. (Kinerase wasn't kidding when it named it the "ultimate" moisturizer!)

To enter the giveaway, leave a comment in the comments section below by 5 p.m. PDT / 8 p.m. EDT Thursday, June 21, and we'll announce the winner tomorrow when we post the next giveaway. Please, only ONE comment per person; duplicate comments will be discarded, so commenting more than once won't up your chances of winning.
