WHAT IT IS:
Not all eye shadow primers are created equal. But this primer makes promises it can keep--long-lasting shadow wear and vibrancy, with absolutely no creasing.
WHAT IT DOES:
The silky-smooth, waterproof formula holds pigment in place and delivers nude, barely-there color that evens out eyelids and leaves them with a natural, matte finish.
HOW TO USE IT:
Apply with fingertips under your favorite Lancôme shadow.
