These Are the 16 Beauty Launches You Need to Know For October

"There's nothing I love more than a bold cat eye, so a potent liquid eyeliner is always an essential part of my makeup bag. I've been achieving even wings with the Revlon ColorStay Liquid Eye Pen ($9) in Blackest Black. Unlike most liquid eyeliner pens, this one comes with a rounded ball tip to make drawing on precise lines a breeze. Its long-wear formula lasts up to 16 hours so it won't budge if you have oily eyelids or frequently work up a sweat." — Aimee Simeon, editorial assistant, Trending
