A true testament to a product's greatness is when it elicits compliments every time you wear it. Pixi Endless Silky Eye Pen in Oyster Glow is one of those rare specimens. We trace the pinky-beige gleamy pencil along our bottom lashline no matter what eye shadow, liner (or lack thereof) we're wearing-- it lends an ethereal brightness to tired eyes and distracts from dark shadows. Its eye area-awakening abilities trump all forms of caffeine and any eye cream we've ever used. People are constantly asking us what the magic liner is, and now the secret's out. Tell us: What beauty product always earns you compliments?
